At April 08th 2018, R&D Software Solutions srl [] revealed to the public the announcement of the xyz-mIoT by shield - the first, and the most compact, IoT board that combines the versatility of ARM0 micro-controller (Microchip/Atmel ATSAMD21G in Arduino Zero compatible design), the comfortable use of the embedded sensors bundle with connectivity provided by LPWR LTE CAT M1 or NB-IoT long-range & lowpower modems or legacy 3G / GSM modems.

Driven by the power and versatility of the embedded ARM0 (ATSAMD21G) core and by interfaces [I2C, SPI, UART, 13 digital I/O – 1WIRE and PWM capable, 5 analog inputs and more], “xyz-mIoT by” provides multiple interfacing with devices, sensors and actuators and enables. The xyz-mIoT shield may have up to 5 integrated sensors, as: THS (temperature and humidity sensors) – HDC2010, tVOC & eCO2 (air quality sensor - CO2 total volatile organic compounds- CO2 equivalent) - CCS811, HALL (magnetic sensor) – DRV5032 sau or IR (infrared sensor) KP-2012P3C , secondary IR (infrared sensor) – KP-2012P3C, TILT (movement vibration sensor) or REED (magnetic sensor) – SW200D. The embedded sensors that populates the xyz-mIoT shield are dependent on PN ordered. In order to highlight the advantages given by advanced design and sensors integration, take a look at brief comparative chart with other LTE CATM1/LTE NB-IoT:

Step 1 ▶ connect Vusb with Vraw, solder over SJP6

xyz-mIoT by design was driven by two strategic directives: • IOT for everybody – one IoT platform that may be used in natural manner but having the power and versatility in order to be used by both professionals and hobby and do it yourself enthusiasts. Obvious Arduino programing was the best choice available; in addition, the professionals will be more than satisfied regarding about multiple hardware and software setup capabilities. • IOT democracy (Democrația IOT) – anyone to be able to set (in around 15 minutes*) his own IOT sensor with CLOUD data logging. Bellow, I will show to you how can be done temperature and humidity CLOUD data logging using the xyz-mIoT shield (xyz-mIoT board used must have HDC2010 embedded, select PN as: XYZMIOT209#BG96-UFL-1100000, or GSM only variant XYZMIOT209#M95FA-UFL-1100000), Arduino board programming support and Robofun CLOUD.

Solder over the two pads of SJP6 (connect USB 5V with Vraw) Enable 5V from USB to be as primary power supply for the board as described up here. Alternative: solder both connectors rows, place the board into one breadboard and connect between Vusb and Vraw using one male-male breadboard wire

Step 4 ▶ Let make a new account on Robofun CLOUD (available at: Add two new sensors (xyzmIOT_temperature and xyzmIOT_humidity). For each sensor, retain the "Tocken" id value (scroll-down in sensor page to find it).

Press twice (fast) the xyz-mIoT shield RESET button [the board will switch into programming mode]. Select " xyzmIoT" programming port in Arduino menu. Compile and upload the code. The xyz-mIoT shield will start to sample the temperature and humidity data (at 1min. rate) and to upload sampled values to the CLOUD.

Those values will be used, next, to set sensors id[token id] in Arduino code. In the same page, a little bit above, you will find the public Internet address where you will find the sensor data (observe marked in above picture). Step 5 ▶ Open in Arduino ( v >= 1.8.5) the xyz_mIoT_v41_temp_humidity.ino project. Set tempTocken and humiTocken values with the one retained in previous step [created in the CLOUD]. If you use xyz-mIoT shield equipped with BG96 module you can select network registration mode as "GSM mode" or as "LTE CATM1 mode" (mobile network used and SIM card must support LTE CATM1*) by calling client.setNetworkMode(GSMONLY), respectively client.setNetworkMode(CATM1ONLY) function,



In order to visualize the debug output use the Arduino Serial Monitor or other terminal by selecting the debug port with following settings: 115200bps, 8N, 1. The temperature logged data can be visualized in Robofun cloud sensor page or, in public (shared) page as we specified in Step4.

The SCALE-iDriver™ from POWER INTEGRATIONS, which is available at CODICO, is an innovative IGBT gate driver, and brings many benefits to a motor drive inverter. This document discusses the feasibility to reduce costs on system level by using this gate driver from POWER INTEGRATIONS™. SWITCHING OFF AN IGBT WITH NEGATIVE VOLTAGE BY USING A UNIPOLAR POWER SUPPLY The idea to work with a unipolar power supply to switch the IGBTs isn’t new. The problem so far was that the turn off voltage is 0V and not negative. Many designs failed in the past, because of parasitic turn on due to dV/dt in the system. The typical threshold voltage of an IGBT is around 6V. If a parasitic Voltage between Gate and Emitter occurs in the range of 6V the IGBT can turn on and lead to a system stop. The SCALE-iDriver™ has an integrated voltage regulator for the turn on voltage. This means the supply voltage can be a unipolar

and unregulated 22V-30V supply (Vtot). The SCALE-iDriver™ generates a regulated +15V voltage to turn on the IGBT. The turn off voltage is the difference of the supply voltage and the regulated +15V. Example: Vtot = 22V → Voff = -(22V-15V) = -7V COST SAVINGS • Using Simple Transformer (will be available from Power Integrations soon) • Less Rectifiers for DC/DC needed • No external voltage regulator needed • No need of suppressor Diode for Gate Emitter protection (simple diode from Gate to +15V).

REDUCING ISOLATION BARRIERS OF SENSORS WITH AN REINFORCED ISOLATED GATE DRIVER (acc. to VDE0884-10/17) Most motor drives use engine speed sensor or current sensors to get a feedback of the motor state. From a cost perspective these signals shouldn’t be transferred over an isolation barrier to a Microprocessor which is connected to a high voltage. For cost optimization – and in most cases also technical wise – the best solution is a Microprocessor on SELV level (earth potential) like shown in the picture on the right side. But therefore a reinforced isolated gate driver is needed. 9


SCALE-iDriver™’s reinforced galvanic isolation is provided by Power Integrations’ innovative solid insulator FluxLink™. FluxLink™ is a magneto inductive technology to transfer the PWM command signals from the primary (IN) to secondary side. Thanks to this technology the SCALEREDUCE iDriver™ is providing safe isolation between primary side (LDI) and secondary-side also after the secondary side chip (IGD) has blown up due to an IGBT fail.

COST SAVINGS • No further isolation barrier for driver and feedback signals needed • Less costs for isolation barriers for other sensors • Reduce qualification and certification efforts • Higher quality of inverter possible

LESS COMPONENTS NEEDED TO GET THE NEEDED PEAK CURRENT VALUE The SCALE-iDriver™ is available with 2.5A, 5A and 8A output so far. The 8A output is the highest output current for gate drivers available in the market. Until 8A no external booster is needed. This 8A are regulated and available over the full temperature range of -40°C to 125°C ambient temperature. For turn on and turn off current two separate Pins are provided. No external diode for splitting 10

turn on and turn off current is needed. Regarding the internal current regulation over the full temperature range even no external gate resistor is needed. COST SAVINGS • No need of external booster up to 8A • No diode to separate RGon and RGoff needed • Possibly no gate resistor is needed

USE OF SMALLER IGBT The SCALE-iDriver™ has an N-ChannelMOSFET output stage which leads to a very low output impedance. The output current can be higher by using the same gate resistors compared to another driver with same current rating. Measurements have shown that this can reduce the turn on (Eon) losses of an IGBT up to 70%. At the same time the turn off losses (Eoff) are still the same. Depending on the switching frequency and the design criteria for selecting the IGBT current this reduce of switching losses can lead to a smaller and so more cost efficient IGBT. COST SAVINGS • Use of smaller IGBT

INTEGRATED OVERCURRENT PROTECTION: LESS CURRENT SENSORS AND ELECTRONICS NEEDED Protecting the IGBT against overcurrent is a must have of every motor drive. In most IGBT applications the usage of a gate driver with De-saturation detection (DESAT detection) protects the IGBT against high current that would lead to a destruction of the IGBT. The principle is that an IGBT desaturates at roughly four times of the nominal current. Then the IGBT is getting high impedance and the Collector – Emitter voltage (Vce) will rise up to the DClink voltage. DESAT detection can detect this voltage and the driver will safely shut off the IGBT. Unfortunately typical DESAT detection can lead to false tripping due to forward recovery - especially in applications with dynamic loads like servo motor drives- after the so-called blanking time. Therefore, most of the inverter manufacturers designed out the DESAT function and use other solutions like measuring the current with costly current sensors. A current sensor for every phase leg is needed, so three current sensors are required for a three phase inverter. Ideally, design should help to turn off IGBT before reach two Electronica Azi International | 3/2018


times nominal current. This means a lot of engineering effort and also a software adaptation for every different motor drive is needed. The DESAT detection of the SCALE-iDriver™ provides a response time instead of a blanking time. Short voltage spikes are ignored and the DESAT detection can be used again for overcurrent protection also in servo motors. After a DESAT event is detected, SCALE-iDriver™ will turn off the IGBT with its patented Advanced Soft Shut Down (ASSD) function. This ASSD principle is a closed loop Gate feedback which is working without any addi-

tional external components. The short circuit event will be reported by the SO pin to primary side. By handling the overcurrent with the driver it isn’t needed to know the current of each phase. The current of the three phase system could now be measured with the Aron measuring circuit which needs only two current sensors. COST SAVINGS • Using resistor chain instead of high voltage diodes • Less effort for current sensing/signal processing

• Only two current sensors for AC current needed • No software adaptation for different currents OTHER BENEFITS OF SCALE-IDRIVER™ • FluxLink™ as transformer based insulation technology • 5V CMOS input, Open Drain Failure Output • Under voltage lockout for primary and secondary side • Operation ambient temperature -40 to 125°C • Maximum Case Temperature 150°C • Design ready for 2-layers board • UL certified (E358471) • High Switching frequency of 250kHz • High EMC robustness If you wish to receive more information in the product, please get in touch with your CODICO contact or Mr. Ivan Mitic, Regional Sales Manager at CODICO.

SIMO SwItchIng RegulatORS extend BatteRy lIfe In SMall devIceS By Cary Delano, Distinguished Member of Technical Staff, and Gaurav Mital, Principal Member of Technical Staff, Mobile Power Solutions, Maxim Integrated

Portable battery-powered devices such as earbuds, smartwatches, and gaming controllers are expected to deliver long-lasting performance for a better user experience. The challenge for designers lies in extending battery life when battery capacity is limited by the small form factor of these electronic products. The right power management architecture can make all the difference in delighting or disappointing end users. This article takes a look at how a single-inductor multiple-output (SIMO) power converter architecture balances battery life versus space constraint demands of products like hearables and wearables. SMALLER FOOTPRINT, HIGHER EFFICIENCY Let’s consider a typical power management system for a hearable device. Such systems usually have a power management IC (PMIC) that offers a battery charger, a buck converter, and low-dropout regulators (LDOs). For example, a dual LDO may power the Bluetooth and audio. In a typical implementation, overall efficiency is under 70% because the LDOs are used for multiple rails. To improve efficiency, one option is to use switching regulators instead of LDOs. However, each switching regulator would require a separate inductor for each output in order to service each voltage rail. Considering how large and expensive inductors are, this implementation isn’t practical for very small electronics. Conversely, a SIMO architecture provides 12

much greater efficiency, particularly for products powered by small lithium-ion batteries. Consider a SIMO buck-boost regulator provided by Maxim as an example (MAX77650). Maxim’s SIMO buckboost regulators have a single inductor that regulates up to three output voltages

over wide output voltage ranges. This approach results in a smaller total footprint compared to the traditional architecture by eliminating multiple discrete components. It also delivers high efficiency. Figure 2 depicts a diagram of the SIMO buckboost regulator.

• Reduced cost and footprint • Quantization of available component values • Time multiplexing when different features in the end device aren’t used at the same time, allowing them to share their required ISAT − a useful benefit for events that occur sequentially using different rail voltages • Averaging − even when channels aren’t time-multiplexed, peak power consumption of different features does not occur simultaneously, which can lower the total inductor ISAT requirement TACKLING SIMO ARCHITECTURE TRADEOFFS A well-thought-out design illustrates the tradeoff benefits inherent in the SIMO architecture. Ripple voltage tends to be higher with SIMO devices, for example, because a single inductor is providing buckets of energy to alternate outputs. Also, the output voltage ripple may increase because when the SIMO is heavily Figure 1: loaded, it becomes time-limited and there Portable electronics such as fitness trackers can be a delay in servicing each channel. must offer long battery life for a pleasing You can offset the sources of output voltuser experience. age ripple by implementing larger output caps, which would allow you to maintain a net footprint/BOM advantage. A SIMO architecture may also exhibit more In Table 1, you can see a comparison of the crosstalk than its traditional counterpart. SIMO architecture versus a traditional Maxim has several SIMO PMICs that can power management solution. The SIMO is help you manage these tradeoffs. Two of able to deliver high efficiency on each out- them are the MAX77650 and MAX77651, put with this architecture. The converter which integrate a battery charger and regumaintains the low loss of a traditional induc- lation for powering the sensor, the microtive switching converter by still turning on controller, Bluetooth, and audio. Overall switches with near-zero volts across the system efficiency is 8.9% higher compared devices, which keeps the dissipation low. to the alternative solution presented in The SIMO device also time-shares the Table 1. The devices feature micropower inductor to each output using low-loss SIMO buck-boost DC-DC converters as switches, a technique that allows it to keep well as a 150mA LDO, which provides ripthe same high-efficiency benefits that would ple rejection for noise-sensitive applicabe expected from a buck-boost converter. tions like audio.

Table 1: Comparison of SIMO architecture with traditional power management solution. Inductor saturation current (ISAT), which provides an electrical current measure when the inductance drops to 70% of its value, is based on the inductor’s core size for a given core material and construction. Compared to using separate DC-DC converters, the SIMO architecture with a single inductor provides many advantages:

undershoot on bus signals, while also protecting device inputs from high-voltage spikes on the bus lines, there are optional resistors in series with the serial data line (SDA) and serial clock line (SCL). To further minimize crosstalk and also prevent oscillation, the devices always operate in discontinuous conduction (DCM) mode, so the

inductor current goes to zero at the end of each cycle. The PMICs also help extend battery life for the end applications as each of their blocks has low quiescent current (1μA per output). Since the devices offer highfrequency operation, they can use a small inductor. The devices are available in a 2.75mm × 2.15mm × 0.7mm WLP package. Compared to a buck-only SIMO, a buckboost topology makes good use of the inductor because it needs less time to service each channel. With a buck-only SIMO, operation suffers when an output voltage approaches the battery voltage, as the device would require the inductor for too much time, thus affecting other channels. Generally, solutions that need at least one boost voltage are better served with a buck-boost SIMO. HEARABLE USE CASE: NO SACRIFICES WITH SIMO Designing hearables, in particular, involves addressing some unpleasant tradeoffs. Many hearable devices integrate one or more optical or inertial MEMS sensors and also utilize LEDs. Using photoplethysmography (PPG), an integrated optical sensor can measure health parameters such as pulse rate and blood-oxygen saturation. In order to generate the light intensity needed in these types of devices, the LEDs must run at a higher voltage range (4V to 5V) than lithium-ion batteries typically provide. As a result, designers are left with a few choices. They can add a buck-boost to their system, which means another device. They can add another inductor and additional capacitors, which also takes up valuable real estate. Finally, they can opt to live with the higher power dissipation, not an ideal scenario when it comes to small electronics since the battery size is important. SIMO buck-boost technology, however, allows designers to use one of the outputs, set to the desired voltage (up to 5.2V) to drive the LED and also enhance sensor performance. SUMMARY When an electronic device is as small as an earbud or a medical patch, you can imagine how limited the battery capacity is. Yet, longlasting performance is important for the user experience. Traditional power management architectures, with their use of large inductors, aren’t suitable for these types of devices. A SIMO architecture, on the other hand, offers advantages in efficiency and extended battery life in a much smaller footprint. Maxim Integrated 13


WHO NEEDS A TRANSFORMER? Kansal Mariam Banu Shaick Ibrahim from Microchip Technology discusses how to save costs by adopting a transformerless design when Ethernet devices need to communicate over a known distance. Applications that are sensitive to cost use short distance PCB connections, or even operate in extreme environmental conditions may benefit from operation without the use of a transformer. A magnetic-less design could be applied anywhere when two known fixed Ethernet devices need to communicate over a known distance. An example is when the devices are communicating on the same PCB board or across a backplane, as in a VME chassis. To appreciate non-typical transformerless application development constraints, it is first necessary to understand physical network services and signalling, and the functions that transformers provide in typical applications. A typical network configuration consists of a point-to-point connection, through a cable, between two physical layer devices. Figure 1 shows a schematic for a typical transformer interface for PHYs that employs current-mode drivers. The transmitter and the receiver of each node are DC isolated from the network cable by 1:1 transformers. Transformers provide the functions of DC isolation from the cable and DC biasing at the physical layer device. Isolation is necessary to meet IEEE 802.3 AC and DC isolation specifications for cabled configurations. Similarly, figure 2 shows a schematic for a typical transformer interface for PHYs that employs voltage-mode drivers and on-chip terminations. CONFIGURATION To meet the operational requirements of non-typical transformerless network applications, it is necessary to implement physical layer component transmit and receive separation and biasing as well as high-voltage DC isolation to meet the specific safety requirements of the application. For non-typical applications, the isolation the transformer 14

provides in typical configurations can be realised using non-polarised capacitors. A typical network configuration provides

the services of auto-negotiation, auto-MDIX, 10Mbit/s operation and 100Mbit/ s operation. Auto-MDI-X refers to versions

of the medium dependent interface (MDI) that detect if the connection would require a crossover, and automatically chooses the MDI or MDI-X (with crossover) configuration to match the other end of the link. Auto-negotiation and auto-MDI-X should be disabled in a transformerless application and a current controlled PHY. This can be done because both PHYs are under local control. With a voltage controlled PHY, it does not matter if auto-negotiation is disabled or enabled. The system designer can configure a specific speed and duplex on both devices to ensure proper communications. Based on lab testing at Microchip, two PHY devices can link and communicate successfully with both auto-MDI-X and auto-negotiation enabled, but there are a few seconds of delay from reset to link. Disabling autonegotiation and auto-MDI-X will prevent this time delay during system start-up. The IEEE 802.3-2008 specification requires the TX and RX lines to run in differential mode. The TXP and TXN lines form a differential pair and need to be designed to 100立 differential impedance for long distances and 50立 differential impedance for short distances. The RXP and RXN lines also form a differential pair and need to be designed to appropriate differential impedance targets.

link-partners and automatically selecting the highest performance mode of operation supported by both sides. The Microchip LAN and KSZ product lines of Ethernet PHYs, controllers, switches and EtherCAT controllers have been tested successfully for auto-negotiation. Auto-negotiation can be disabled by clearing the auto-negotiation enable bit of the PHY basic control register. The transceiver will then force its speed of operation to reflect the information in the PHY basic control register speed select LSB and duplex mode. These bits are ignored when auto-negotiation is enabled. AUTO-MDI-X Auto-MDI-X facilitates the use of Cat-3 (10baseT) or Cat-5 (100baseTX) UTP interconnect cable without consideration of the interface wiring scheme. If a user plugs in either a direct connect LAN cable or a crossover patch cable, the transceiver can configure the TXPx/TXNx and RXPx/RXNx twisted pair pins for correct transceiver operation. The internal logic of the device detects the TX and RX pins of the connecting device. Since the RX and TX line pairs are interchangeable, special PCB design considerations are needed to accommodate the symmetrical magnetics and termination of an auto-MDI-X design.

PHYSICAL CONNECTION Figure 3 shows the physical connections for the Microchip LAN9XXX devices which have integrated PHYs with current-mode drivers. The LAN8XXX products and the KSZ88X1 also have current-mode drivers. The transmitter output is designed to sink current into a transformer. When the transformer is not used, load resistors must be connected at each device to develop the output voltage. The RX pins are configured with 50立 to the supply for auto-MDI-X operation where they may be configured as TX pins. If auto-MDI-X is disabled and RX pins are for receive mode only, then the external termination can be tied in any way possible as long as there is 100立 differential across the pins.

AUTO-NEGOTIATION The purpose of the auto-negotiation function is to configure the transceiver automatically to the optimum link parameters based on the capabilities of its link partner. Autonegotiation is a mechanism for exchanging configuration information between two

Software based control of the auto-MDI-X function can use the auto-MDI-X control bit of the PHY special control and status indication register. When the auto-MDI-X control bit is set to 1, the auto-MDI-X capability is determined by the auto-MDI-X enable and auto-MDI-X state bits of the PHY special control and status indication register.

Figure 4 shows the physical connections for the Microchip KSZ8081/KSZ8091 Ethernet PHY transceivers with voltage-mode drivers and on-chip terminations. With the voltage-mode implementation, the PHY transmit drivers supply the commonmode voltages to the two differential pairs. 15


With on-chip terminations, no external load resistors are needed. DISTANCE CONSIDERATIONS When designing a system to connect two Ethernet devices without transformers, the distance between the two devices impacts the hardware required. As a general guideline, any distances less than approximately one meter would fall into the short distance category, and any distances over one meter would fall into the long distance category.

For short distances, the 50Ω resistors can be combined to give a single 25Ω resistor. For long distance communications, both Ethernet devices should have terminating resistors on each analogue pin. Examples of long distance configurations include backplane-connected devices or long cable connected cards. Proper laboratory validation should be performed to provide optimum resistor placement. Cable connections over very long distances without transformers are not encouraged due to

KSZ8041 − Employs Current Mode Drivers and does not have On-chip Terminations − Requires external 49.9 Ohm pull-up termination resistors for 3.3VA (transceiver supply) KSZ8081/91 − Employs Voltage Mode Drivers and On-chip Terminations − Requires no termination resistors for Capacitive Coupling (Transformerless PHY-toPHY connection) Figure 6: Connections between current-mode drivers and voltage-mode drivers with on-chip termination

the risk potential for high voltage build-up and noise effects. EXAMPLES The LAN9XXX devices do not require DC blocking capacitors at the RX pins. When connecting to another Ethernet device, it may be necessary to include capacitors. An example of connecting to the LAN9115 single-chip 10/100 Ethernet controller is shown in figure 5. A PHY with voltage-mode drivers and onchip terminations can be connected to a PHY with current-mode drivers and external terminations Figure 6 shows the physical connections between Microchip KSZ8081/KSZ8091 and KSZ8041 Ethernet PHY transceivers. CONCLUSION The Microchip LAN and KSZ devices may be configured in non-typical transformerless network applications to transmit and receive reliably. Recommendations include the use of non-polarised capacitors for DC isolation from a network cable, with a minimum DC isolation rating that suits the individual application. Microchip provides various products to support next generation Ethernet PHYs, switches, EtherCAT industrial controllers and a 10/100 Industrial Ethernet MAC and PHY controller. Microchip Technology

Cyber security in automotive applications

TPM security controllers cover a standardized spectrum of security functions. Protection already begins in the production process as the security controllers have an individual personal key allocated to the chip. In particular, TPM controllers as the main memory for security-critical keys and certificates enable the secure transfer of new keys.

Author: Martin Motz, Product Manager CPU

The importance of vehicle cyber security is growing due to the increasingly dominant role of the Internet and remote applications as well as the trend towards fully autonomous vehicles. Although cyber security is well known as a part of daily routines in the traditional IT sector, it is not yet widespread practice in the automotive industry. At first glance, this appears to be a minor problem as there is an array of solutions from other sectors that could possibly be used for vehicle safety. However, the automotive-specific environment makes this further use somewhat difficult. Today, customers expect the unlimited availability and networking of smartphones and other personal mobile devices in automobiles, as well as the application of cuttingedge satellite navigation systems with a high

demand on the quality of the display and the density of information - in short, complete networking. A constant data connection with an external infrastructure or external devices will also be needed in the future.

Networked automobiles demand a high level of cyber security. 18

Vehicles will thus become a target for cyberattacks and other manipulation. The focus is therefore certainly on guaranteeing confidentiality, integrity, and authenticity - which will ultimately require additional protective measures. The various communication units - from OEM backend system to the vehicle and within the individual control units (ECUs (Electronic Control Units)) - demand secure authentication and protection against data manipulation. To guarantee this, encryption key-based cryptographic methods are used for communication. An encryption process is basically a cryptographic method that uses an encryption key to convert plain text into cipher text which can then be translated back into plain text using a cipher key. The non-disclosure and protection of these encryption keys are - besides other factors a fundamental requirement for the security architecture. Because if the availability and confidentiality of the keys are breached, overall security is compromised. The impacts on the automotive industry might be disastrous - and potentially fatal to its finances and extremely damaging to its reputation. If attackers know the relevant keys, they can influence the communication. In other words, the vehicles would need to be taken to a secure environment (workshop or even factory), which is stressful and costly in terms of both time and money. Electronica Azi International | 3/2018

CYBER SECURITY Against this background, the non-disclosure and protection of the archived keys are essential for cyber security and fully functional security (pursuant to ISO 262262) in cars. TRUST ANCHORS Hardware-based trust anchors can be used to protect archived encryption keys. In this case, measures must be taken to ensure only the authorized entity has sole access to the encryption service of the trust anchor. The trust anchors represent a secure, isolated environment in which the keys and certificates are saved and processed. A number of hacker attacks have clearly demonstrated that implementation of these trust anchors in software (as part of the microcontroller operating system) is inadequate. Implementation of dedicated hardware offers more effective and better protection. Based on these facts, SHE (Security Hardware Extension) modules and HSMs (Hardware Security Modules) were developed and integrated into microcontrollers. The Infineon AURIX™ microcontrollers have, for instance, an integrated HSM, with second generation HSMs (TC3xx) additionally supporting asymmetric cryptography (key pair consisting of a private and public key). Particularly efficient protection, especially for security-critical areas, such as outward vehicle communication or the infotainment sector, is offered by special security controllers like OPTIGA TPMs (Trusted Platform Modules). The TPM guarantees secure authentication. To achieve this, it stores utilized certificates and relevant keys

long-term in a protected environment. Various functions are implemented in the hardware-based trust anchors to protect security-critical processes and, for example,

The HSM (Hardware Security Modules) in AURIX™ microcontrollers are used as trust anchors and isolate security functions from the other functional units of the microcontroller.

These analyze, e.g., the runtime of the algorithm, the electric power being consumed by the processor during the calculations or the electromagnetic emanation to divulge information about the keys. The following principles apply to data security in automobiles: • The integrity of electronic keys is a major factor for the data security of an electronic system. • It is impossible to achieve a sufficient level of data security with manipulated or easyto-manipulate electronic keys. • Cloned electronic keys do not leave any traces. • Secure handling of electronic keys must be guaranteed throughout a product’s entire life cycle. • Trust anchors enable key administration and application in an insecure environment (e.g. during vehicle operation).

Product portfolio for security-relevant vehicle applications

Integrated on MCU (HSM) ▶ Onboard security ▶ Protected com. & debug interfaces ▶ High-speed/real-time critical tasks Discrete Security Controller ▶ Protected external communication ▶ Certified hardware security ▶ Protecting critical keys & certificates Hardware-based trust anchors and their range of applications in cars

the transfer of keys. In this respect, the functional complexity (the code) is, in comparison to the controllers being protected, relatively small. The reduced complexity enables comprehensive testing of the hardware and software, which is not financially feasible for an entire system. The use of microcontroller (HSM), TPM or SIM-based solutions as trust anchors in cars is determined by the respective application. Implementation via HSM (integrated in the microcontroller) is basically aimed at in-vehicle communication, which demands a high level of computing performance and a robust real-time behavior. Conversely, special TPM controllers secure the external communication, which poses a higher risk for cyber security. Furthermore, they can be used as the main storage for security-critical keys and certificates. They also offer protection from so-called side-channel attacks.

EFFICIENT PROTECTION THROUGH STANDARDS In the meantime, carmakers classify data in terms of their security relevance. The respective classification also impacts the required measures or the justified protection for the corresponding keys. The lifespan of electronic keys is relevant as well. Electronic keys with a higher demanded lifespan offer greater protection than electronic keys that can only be used for a limited period (session keys). The actual reuse of established, widespread algorithms and procedures for security mechanisms and implementation reduces the level of specific effort related to vehicle data security. After initial negative experience using in-house developed proprietary algorithms, standardized encryption techniques, including AES, RSA, and ECC, have become the norm in the automotive industry. 19

EMBEDDED SYSTEMS Although the re-application of existing and proven security technologies is desirable, cars have other specific requirements that need to be addressed: Cars need to meet higher quality standards under robust operating conditions, offering greater reliability and above average life expectancy. Data security solutions from the world of chipcard technology are already in widespread use. In terms of their application in vehicles, an extended temperature range and common qualification standards also need to be considered – an example of security controllers in this respect is SIMs. The automotive industry therefore relies on robust, solderable SIM technologies to meet requirements in terms of vibrations, extended temperature range, and the automotive standard AECQ-100. FULL LIFE PROTECTION The encryption keys used in cars must, depending on the key management and techniques, be protected throughout the vehicle’s entire life cycle, from production and use through to disposal. Production is a particularly critical phase within this process. As this is the point where keys must be transferred in plain text. If this process is not protected adequately, attackers can gain access to a large number of keys. Further, key injection may be performed at several locations and by subcontractors, which puts greater pressure on security processes and resources. An efficient solution is the application of a personalized security controller. Personalized in this case means the security controller has an individual personal key allocated to the chip which was stored by the semiconductor manufacturer during a certified manufacturing process. Seeing as these security controllers are protected from hardware attacks, they can be supplied without any special logistic requirements. Since they can only be manipulated using the personalized key. A personalized security TPM controller additionally facilitates the personalization process of the control devices, as the protected private key in the controller can be used to transfer further keys via secure communication. The safety of a product depends on the quality of the security processes and should play an integral part in the product development and production phases. For instance, the development and production process of the OPTIGA TPMs is certified to Common Criteria. The current version of the Common Criteria was issued in 1999 as the international standard ISO/IEC 15408 and specifies the criteria for evaluating and certifying the reliability, quality, and trustworthiness of IT 20

products. Furthermore, the TPMs are produced and personalized using manufacturing processes that are also fully audited and certified. This strict monitoring of security processes by independent or stateapproved certification bodies is the foundation for the high level of security quality provided by Infineon’s TPMs. Another critical factor is the long life expectancy of vehicles of up to 20 years or more. A further demand is that the implemented crypto algorithms are also secure throughout the vehicle's entire service life. To enable this, the security architecture should facilitate simple crypto functionality switchover, possibly support both old and new algorithms in parallel, and offer sufficient hardware resources (buses, memory, etc.) for new, longer keys. This socalled “crypto agility” is supported, e.g., by the TPM 2.0 standard.

Microcontrollers with HSM and TPM security controllers offer, for example, hardware-based security mechanisms for the various functions of a SOTA application within the vehicle. EXAMPLE OF SOTA APPLICATION Costly recall actions to eliminate software problems in vehicle control units have forced carmakers to increasingly consider the opportunities that would arise from performing software updates over the air (SOTA). Besides the saved callback costs, the mobile connection to the vehicle and the option to download new software via this communication interface enable new functions and applications. Dedicated security solutions provide hardware-based security mechanisms for various functions in a SOTA application within the vehicle. In addition to end-to-end communication between OEM server and target control unit, the vehicle architecture for SOTA can be

implemented via three control units (ECU blocks) where different security solutions assume the respective security functions: Telematics control unit, central gateway, and target control unit. The authentication and encryption services are activated in the telematics unit using the wireless connection and the transmitted data (from the OEM) are then received and decrypted using a secure protocol. The implementation of a dedicated TPM security controller is recommended for this critical authentication function to protect the security-critical keys and certificates. Subsequently, the software update is stored in the vehicle’s main memory. After OEM authentication and verification (in the central gateway), the respective data packages are unpacked for the control units. The actual update process with programming then commences and the data packages are sent in small blocks to the ECUs. Within the ECUs, the data blocks are decrypted, decompressed, and a new code is written in the flash memory of the target control unit via the secure flash bootloader. The secure flash bootloader is a key element for the SOTA process within the control unit. The main security functions are, for instance, executed by the HSM in the AURIX™ microcontroller: Secure booting, authentication, decryption and encryption, key management, and integrity check. Authentication for flash access prevents unauthorized read and write access to the flash memory. Flash access is only enabled by the HSM after successful authentication of the central gateway and after sending a respective programming command. After successful verification of the update, this is reported to the update server. At the end of the update mode, the vehicle is rebooted or started with all the ECUs. CONCLUSION State-of-the-art semiconductor solutions enable vehicle security systems with high functional security and cyber security that protect the vehicle as well as car and road users. Optimized for specific applications, 32-bit microcontrollers with integrated hardware security modules (HSM), SIM controllers, and special TPM security controllers, as well as corresponding software packages are available. This way it is possible to adapt the respective security mechanisms to the security requirements of a particular application. Utilization of proven crypto algorithms, e.g. AES and ECC, as well as adherence to standards, e.g. SHE, EVITA, and TPM, minimize the risk and the integration effort for OEMs, their suppliers, and sub-suppliers.

RUTRONIK PRESENTS THE NEW ACCELEROMETER FROM BOSCH SENSORTEC Rutronik is adding the BMA400 accelerometer from Bosch Sensortec to its portfolio. It features ultra-low power consumption without compromising on performance. The sensor is available to order on The BMA400 allows continuous, low-noise measurement of motion on three axes with 12-bit digital resolution and several selectable bandwidths. The ultra-efficient sensor detects tilting movements, linear motion, and tapping / double tapping. It also tracks the level of activity and counts the number of steps taken, making it ideal for a number of applications in various areas, including the smart home / IoT, wearable devices, industry, and energy management. The integrated step counter and embedded activity tracking function consume just 4 μA of power in total. In ultra-energy-saving mode, the power consumption can be reduced even further to 800 nA. An automatic wake-up function can then return the sensor to normal operating mode when required. In terms of power consumption and noise suppression, the BMA400 is highly configurable and can work in two operating modes. Therefore, the greatest possible flexibility is ensured when integrating the sensor into always on low power systems. With standard data capture, the acceleration data is continuously read out via the sensor’s digital interface and processed by a microcontroller or processor. An integrated 1kB FIFO buffer as well as an auto wakeup mode and an auto power-saving mode are also available. During normal operation, a current consumption of significantly less than

4μA is possible. With the plug and play function, data processing takes place in the chip itself. If the sensor detects predefined situations, it triggers an interrupt signal. Both the cause of the interrupt signal and other recorded data can be read out later on. The sensor is compatible with a wide range of VDD and VDDIO supply voltages; the output and power consumption remain constant at all times. With digital I²C and SPI interfaces (three- or fourwire) and dimensions measuring 2 mm × 2 mm × 0.95 mm, it can be easily integrated into various designs. Rutronik |

HARWIN EXPANDS BREADTH OF ROBUST SURFACE MOUNT 3-POINT PCB SOCKET SERIES High-reliability connector supplier Harwin has announced further additions to its Sycamore Contact ( product offering. While this series was initially capable of accommodating 1mm and 1.5mm diameter contact pins, it now covers pin sizes from 0.80 to 1.90mm. There are a wide variety of scenarios where electronic devices/modules will require replacement over time (such as depleted gas sensors or worn-out energy harvesting transducers). In addition, initial exposure of these modules to soldering temperatures can introduce the risk of early failure due to heat damage. Both these risks show that direct soldering onto the PCB is clearly unadvisable. Removal of a failed or damaged module will prove difficult, and could result in scrappage of the whole board. The Sycamore Contact series of surface mount PCB sockets allow odd-form devices/modules that are not suited to regularly-spaced socket strip arrangements to be attached without any future inconvenience, should removal be required at a later stage. Whereas other contact solutions of this kind only comprise 2 points of contact to the mating pin, making them vulnerable to exposure from vibrational forces, the patent pending design of the Sycamore Contact gives engineers access to 3 contact points. This markedly improves operational stability, as well as delivering stronger pin retention and heightened levels of signal integrity. Available in both top-entry and bottom-entry configurations, these sockets have a current rating of 6A and a 15mΩ (maximum)

contact resistance. Their sturdy construction, which uses beryllium copper with gold plating, means that they support 500 mating cycles and exhibit an operational temperature range spanning from -50°C to +125°C. As these components can be supplied in a tape-and-reel format, they are highly suited to automated production processes, with the surface mount placement feet also serving as the pickup areas for pick-and place machinery.

Martin Warmington, Global Sales Manager

Martin Warmington, Global Sales Manager microchipDIRECT, outlines procurement initiatives which help OEMs and CEMs to optimise inventory management by identifying lead-time trends and using rolling 30-day cancellation windows. INTELLIGENCE-LED LEAD-TIME PLANNING They are a vital part of keeping the production lines rolling but the conventional approach to lead-times can be open to misinterpretation and even mismanagement. The problem with the conventional approach to managing leadtime lies in the different interpretation of the information which is published by semiconductor manufacturers. From the OEM customers’ perspective, the lead-times quoted by the manufacturer at the start of a project’s procurement phase are typically used as a fixed time-scale. This means that the original lead-times are


entered into the manufacturer resource planning (MRP) system and often remain unchanged throughout the pre-production and production stages of the project. The semiconductor manufacturers’ perception of this lead-time information is, however, very different. The lead-times that they publish are correct at the time that they are quoted but they are also subject to change as fluctuations in demand affect factory loading. All it takes is one or more customers to place high-volume orders for the same semiconductor to change the factory loading and to push an 8-week lead-time out to 14 weeks.

Electronica Azi International | 3/2018


It is more realistic, therefore, for OEMs to treat lead-times as changeable trend indicators rather than as fixed time-scales. For example, if a lead-time which was originally quoted at 8 weeks is extended to 12 weeks, the customer should update their MRP system with the new lead-time to ensure that they are always working to the most accurate lead-time. If the change is leadtime is very large over a short space of time the high volume OEM customer should also start to ask questions of their supplier to understand why the lead-time is extending so that they can get a clearer indication of the future lead-time trend. Of course, requesting updated lead-times from multiple manufacturers at regular intervals would stretch procurement resources. This is why microchipDIRECT offers its customers the opportunity to receive a weekly lead-time update on the parts that they are buying and also provides sales order history and invoices which the customer can find in their online account. Used in conjunction with back-log reports, these weekly lead-time updates enable customers to take a more intelligence-led, trend-orientated approach to lead-time management. This approach to monitoring lead-time trends is a vital tool in the procurement of any semiconductor, regardless of whether it is a high or low runner. 30-DAY ROLLING CANCELLATION WINDOWS At the other end of the supply-chain, there is the industry-standard practice of suppliers holding buffer stock. This helps OEM customers to balance the cost of holding inventory against fluctuations in demand from their own end-customers. Whilst this system has many advantages, in the current climate of sharp market volatility, OEMs are finding it increasingly difficult to get visibility of future demand from their end-customers. This is particularly difficult with

new designs where the OEM may not want to commit to inventory until the success of the design has been proven in the field. To help OEMs to overcome the risk of forward inventory planning without clear visibility of future demand, microchipDIRECT has created the 30-day rolling cancellation window. This 30-day window effectively allows a customer to cancel or push out a delivery placed on any standard semiconductor, at any time up to 30 days before the parts are scheduled to be shipped. So, for example, an order placed on the microchipDIRECT website on September 19, for delivery on November 19, could be cancelled or pushed out at any time before October 19. As each new shipment date is reached, the 30-day window is rolled forward, enabling OEMs to lower inventory costs whilst also reducing the risk that their continuity of supply could be compromised. This not only helps microchipDIRECT customers, it also allows them to help their own end-customers by ensuring greater flexibility and responsiveness to market demand. To help customers to manage the rolling 30-day cancellation window, microchipDIRECT can at customers request issue a weekly back-log report showing which products are scheduled for shipment within the cancellation window. This allows customers to focus their attention on imminent shipments and to adjust their schedules to reflect any changes in demand. The management of lead-times and buffer stock has been an important part of industry best-practice for optimising inventory costs for decades. These initiatives provide OEMs with the procurement tools which take inventory management to a new level by delivering greater visibility and tighter control of their semiconductor orders.

Aurocon COMPEC supports the future generation of engineers With a head start in 2010, it already became a tradition that in România, once a year to be organized the competition “The Days of Mechatronics Education”, which brings together teams of students from the great university centers that have Mechatronic domain in their study program. This year, the organizer was the University Lucian Blaga from Sibiu. At the event, the most important university centers in Romania, that “Zilele Educaţiei Mecatronice 2018 - România” are providing mechatronic training, (The days of Mechatronics Education 2018) Internal competition for mobile robots - Qualifying for ZEM 2018 were invited. Those universities are: University of Politehnica Bucharest, Technical University of Cluj-Napoca, University of Craiova, Technical University Gheorghe Asachi of Iasi, University of Politehnica Timisoara, University Lucian Blaga of Sibiu, University Stefan cel Mare of Suceava, University of Oradea, Transilvania University of Brasov. In the competition, the Mobile Robots section is raising a great interest among students. The teams compete in the contest with line follower robots built by students, according with a rules list. The task consists in running on two tracks, one of speed and one of obstacles. The speed track consists in following the line with maximum speed, and the obstacle one consists in the passage of areas where the lines are intersecting, interrupting for a certain distance, areas where a wall type obstacle appears. The contest shows the capability of students to design mechanical systems, to build electronics circuits and to develop and implement robotic control programs. From the desire to be close to the students, the future engineers, Aurocon COMPEC sustained the Mobile Robots team from University of POLITEHNICA Bucharest. 24

Mobile robot solutions of participating teams from the internal qualification contest Electronica Azi International | 3/2018


Thus, at the University of POLITEHNICA Bucharest, 12 teams of students joined the internal selection contest for the Days of Mechatronics Education. Aurocon COMPEC has provided hardware support for the developing of robotic structures (electrical motors, PCB and electronic circuits, microcontrollers, cables, connectors, 3D printing filaments, etc.). Internal competition tracks have also been made by Aurocon COMPEC.

Robot qualified for national competition ZEM 2017 Each team designed a mechanical structure of a mobile robot on wheels, complying with the regulations which limited the dimensions to a volume of 200mm × 200mm × 200mm. Some of the solutions consisted in 3D printed platforms, on which the motors, wheels,

electronic parts and battery were placed. Other solutions started from the idea that the PCB itself can be used as the chassis, considering that the general idea was to keep the structure as compact as possible. It may seem trivial, but a major problem was the optimal distribution of the weight on the wheels, due to which the battery positioning, as a heavy component, played a very important part. In addition to that, a structure that is too light presents the risk of wheel slipping at a certain acceleration, while a heavier one required better motors. The chosen motors were attached to the designed chassis. As for the wheels, some teams purchased some from the market, while others designed them for optimal dimension and maximum adherence. As a result, the solutions were different, all complying to the regulations. Afterwards, the teams chose the microcontroller platform, mainly revolving around the Arduino area. Their choices were based on the number of necessary I/O for the motors, sensors etc. The regulations stated that the drivers for the motors' command must be designed by the students, using embedded circuits, as the solutions already available on the market would not be accepted. For the circuit board, there were two options: a PCB (Printed Circuit Board) or a Perfboard on which you can place the components. The L298 circuit, which is often used in motors' command, turned out to be very successful in this type of project. For the line following part, certain sensors were required, such as: infrared proximity sensors for the line detection (QTR, QTI, TCRT5000), as well as a proximity sensor for the obstacle wall detection (Sharp,

Ultrasonic Sensor). Depending on the loads, the batteries were chosen. Where necessary, the electronic circuit also contained voltage regulators (Eg.: LM7805). Following the local contest held at UPB, the team which qualified to the Mechatronics Education Days 2018 was composed of Emil Ionuț Niță and Andrei Silviu Colgiceanu, 4th year students in the Mechatronics department.

Team present at ZEM 2017 The national competition that came next was held at the Lucian Blaga University of Sibiu, on the 24th - 27th of April, 2018. A particularly high interest was shown towards this student competition by the students and teachers from the previously mentioned universities, as well as companies and mass media representatives attending the event. The Politehnica University of Bucharest's robot has done very well in the competition, placing the team in the first place.

Leuze Electronic: Reliable detection of objects and fill levels Leuze electronic is expanding the portfolio of optoelectronic and inductive switches with capacitive proximity switches, making it possible for users to

obtain complete solutions for all detection requirements from a single source. Leuze electronic is introducing contactless, wear-free switches which are resistant to electromagnetic influences, interference and contaminants in the air such as dust with its new range of capacitive products. The capacitive switches are available in a cylindrical or cubic design, as well as embedded or non-embedded versions for a wide range of mounting options. Due to their semiconductor technology, they have a long-life expectancy, regardless of the detection and switching frequency. The new variants make contactless detection of many different objects and media possible, regardless of the shape. They are particularly suitable for detecting objects in harsh and dirty environments due to their IP67 housing. Because of their ability to “see through” certain materials, they are predestined for use in the packaging industry. They detect products in outer packaging and behind container walls, check fill levels and monitor these for completeness. 29

Whether you’re starting out or expanding, renting is the smart option for your business. Staying Ahead of the Game We live in a time of constant changes where every day we have to adapt to our customers’ needs. Either because of the new technological challenges, a focus on ROI “return on investment” or better productivity against new competition. The reasons can be many, and we believe we can help in providing the right solution. Keeping up with the pace and always being a step ahead of your competitors is what we are all striving to. Today you can rent almost everything starting from airplanes and properties to cars and machines. So, why not rent your next SMT equipment?

Advantages of Renting 1. 2. 3. 4. 5. 6. 7. 8.

It’s the right to use the equipment, and not the ownership, that creates revenue and profit for the company. Rentals can be customized from 18 months, and to customer's needs: monthly, quarterly or annually. Renting allows your company to “protect” your normal bank relationship. Renting allows you to minimize your risk on big asset depreciation. Renting does not affect a take away from the balance sheet as debt-financed assets; it has a positive effect on a number of key figures. Cash Flow; payments are allocated over the period during which the equipment is used and generates profit. (When you have bought the equipment your cash is locked away) Renting strengthens the company’s competitiveness; use your cash where your returns are the greatest. (Production companies often choose to use their cash on new development, salaries or purchase of raw materials which equals the highest return on investment) Flexibility – you are not “stuck” with your SMD-Line. Renting provides you the possibility to change your equipment depending on your customer's demands and market requirements! What equipment fits your business best? To give you a choice in our rental concept, we have created two different product production lines. The first one is called the “PREMIUM SMT CONCEPT” and the second one is called “ECONOMIC SMT CONCEPT”.
