Fundamentals of FPGAs:
What Are FPGAs and Why Are They Needed?
By Rich Miron Contributed by Digi-Key's North American Editors
Designers are constantly looking for ways to architect their systems to provide an optimal computing solution that addresses all their application requirements. In many situations, that optimal solution often requires the use of field-programmable gate arrays (FPGAs), but many designers are woefully unfamiliar with the capabilities of these devices and how to go about incorporating them. This article will briefly describe design scenarios that can benefit from the use of 8
Optimal processing solutions are often provided by combinations of RISC, CISC, graphics processors and FPGAs, by FPGAs on their own, or by FPGAs that boast hard processor cores as part of their fabric. However, many designers are unfamiliar with the capabilities of FPGAs, how theyâ€™ve evolved, and how to use them. This article, Part 1 of a 5-part series, will discuss the fundamentals of FPGAs and introduce example solutions from major providers. Part 2, Part 3, Part 4, and Part 5 will focus on the FPGA device families and design tools offered from Lattice Semiconductor, Microchip, Altera, and Xilinx. FPGAs. It will then go into the fundamentals of how they work before introducing some interesting FPGA solutions and development kits. WHY USE FPGAs? There are a wide range of computing applications, each of which may be best served by a different approach, including off-the-shelf microprocessors (MPUs) and microcontrollers (MCUs), off-the-shelf graphics processing units (GPUs), FPGAs,
and custom system-on-chip (SoC) devices. Deciding which one to use requires a close look at the application requirements and considerations. For example, when working on the cutting edge of technology like 5G base stations, designers need to consider that the underlying standards and protocols are still evolving. This means that designers need to be able to respond quickly and efficiently to any changes in specifications that are beyond their control. Electronica Azi International | 1/2020
DESIGN SOLUTIONS » FLEXIBILITY, PROCESSING SPEED, AND POWER
Likewise, they need the flexibility to respond to future changes in standards and protocols that occur after the systems have been deployed in the field. Similarly, it is also necessary to be able to respond to unexpected bugs in system functionality or holes in system security, to modify existing functionality, or add new functionality in order to extend the life of the system. While the highest performance is typically provided by an SoC, this route is expensive and time consuming. Furthermore, any algorithms that are implemented in the fabric of the chip are essentially “frozen in silicon.” This inherent inflexibility becomes a problem given the considerations outlined above. In order find the sweet spot of optimum performance and flexibility, an alternate route is required. That route is often provided by FPGAs, combinations of microprocessors/microcontrollers and FPGAs, or by FPGAs that boast hard processor cores as part of their fabric. WHAT ARE FPGAs? This is a tricky question because FPGAs are many things to many people. Also, there are many different types of FPGAs, each with different combinations of capabilities and functions. At the heart of any FPGA – the defining aspect of “FPGA-dom,” as it were – is its programmable fabric, which is presented as an array of programmable logic blocks (Figure 1a). Each of these logic blocks contains a collection of elements – including a look-up table (LUT), a multiplexer, and a register – all of which can be configured (programmed) to act as required (Figure 2). Many FPGAs use 4-input LUTs which can be configured to implement any 4-input logic function. In order to better support the wide data paths employed in some applications, some FPGAs offer 6, 7, or even 8-input LUTs. The output from the LUT is directly connected to one of the logic block outputs and to one of the multiplexer inputs. The other input to the multiplexer is directly connected to a logic block input (e). The multiplexer can be configured to select either of these inputs. The output from the multiplexer feeds the register input. Each register can be configured to operate as an edge triggered flipflop or a level sensitive latch (having said this, the use of asynchronous logic in the form of latches inside FPGAs is not recommended). Each register’s clock (or enable) can be configured to be active high or active low; similarly, the active level of the set/reset input(s) can also be configured. www.international.electronica-azi.ro
Figure 1: The simplest FPGAs contain only programmable fabric and configurable GPIOS (a), different architectures augment this fundamental fabric with SRAM blocks, PLLs, and clock managers (b), DSP blocks and SERDES interfaces (c), and hard processor cores (Image source: Max Maxfield) and peripherals (d).
Figure 2: Each programmable logic block contains a collection of elements, including a look-up table, a multiplexer, and a register, all of which can be configured (programmed) to act as required. (Image source: Max Maxfield)
These logic blocks can be thought of as “islands of programmable logic” floating in a “sea of programmable interconnect.” The interconnect can be configured to connect any output from any logic block to any
inputs(s) of other logic block(s). Similarly, the primary inputs to the FPGA can be connected to the inputs of any logic blocks, and the outputs from any logic blocks can be used to drive the primary outputs from the device. 9
Regarding the primary general-purpose inputs/outputs (GPIOs), they are presented in banks (groups), where each bank can be configured to support a different interface standard such as LVCMOS, LVDS, LVTTL, HSTL, or SSTL. Additionally, the impedance of the inputs can be configured, as can the slew rate of the outputs. The next step up the FPGA fabric includes things like blocks of SRAM, called block RAM (BRAM), phase lock loops (PLLs), and clock managers (Figure 1b). Digital signal processing (DSP) blocks (DSP slices) can also be added. These contain configurable multipliers and a configurable adder that allows them to perform multiply-accumulate (MAC) operations (Figure 1c).
which are implemented directly in the silicon (Figure 1d). These hard processor cores may include floating point units (FPUs) and L1/L2 cache. Similarly, peripheral interface functions like CAN, I2C, SPI, UART, and USB can be implemented as soft cores in the programmable fabric, but many FPGAs include them as hard cores in the silicon. Communications between the processor cores, interface functions, and programmable fabric are typically realized using highspeed busses like AMBA and AXI. The first FPGAs, which were presented to the market by Xilinx in 1985, contained only an 8 x 8 array of programmable logic blocks (no RAM blocks, DSP blocks, etc.).
Figure 3: An FPGA can be used to provide an intelligent interface between other devices that use different interface standards or communications protocols, thereby extending the life of existing designs based on legacy devices. (Image source: Max Maxfield) Another common FPGA feature, high-speed SERDES blocks, can support gigabit serial interfaces. It’s important to note that not all FPGAs support all of the aforementioned features. Different FPGAs offer different collections of features targeted at different markets and applications. The programmable fabric in an FPGA can be used to implement any logical function or collection of functions desired, all the way up to a processor core, or even multiple cores. If these cores are implemented in programmable fabric they are referred to as “soft cores”. By comparison, some FPGAs commonly referred to as SoC FPGAs, contain one or more “hard core” processors, 10
By comparison, today’s high-end FPGAs can contain hundreds of thousands of logic blocks, thousands of DSP blocks, and megabits of RAM. In total, they may contain billions of transistors equating to tens of millions of equivalent gates (e.g. 2-input NAND gates). ALTERNATIVE CONFIGURATION TECHNOLOGIES The way in which the functions of the logic blocks and the routing of the interconnect is determined is by means of configuration cells, which may be visualized as 0/1 (off/on) switches. These cells are also used to configure the GPIOs interface standard,
input impedance, output slew rate, etc. Depending on the FPGA, these configuration cells may be implemented using one of three technologies: • Antifuse: These configuration cells are one-time programmable (OTP), meaning that once the device has been programmed there is no going back. These devices tend to be limited to space and high security applications. Since they are sold in small quantities, their price tag is high, and they are an expensive design option. • Flash: Like antifuse-based configuration cells, flash-based cells are nonvolatile. Unlike antifuse cells, flash cells can be reprogrammed as required. Flash configuration cells are tolerant to radiation, making these devices suitable for space applications (albeit with modifications to their upper metallization layers and packages). • SRAM: In this case, the configuration data is stored in an external memory from where it is loaded each time the FPGA is powered up (or as commended in the case of dynamic configuration scenarios). The advantages of FPGAs whose configuration cells are antifuse- or flash-based is that they are "instant-on" and they consume little power. One disadvantage of these technologies is that they require additional processing steps on top of the underlying CMOS process used to create the rest of the chip. The advantage of FPGAs whose configuration cells are based on SRAM technology is that they are fabricated using the same CMOS process as the rest of the chip, and offer higher performance because they are typically one or two generations ahead of antifuse and flash technologies. The main disadvantages are that SRAM configuration cells consume more power than their antifuse and flash counterparts (at the same technology node), and they are susceptible to single event upsets (SEUs) caused by radiation. For a long time, this latter point meant that SRAM-based FPGAs were considered unsuitable for aerospace and space applications. More recently, special mitigation strategies have been employed, with the result that SRAM-based FPGAs are found on systems like the Mars Curiosity Rover, alongside their flash-based cousins. USING FPGAs OFFERS FLEXIBILITY FPGAs are used for many diverse applications. They are particularly useful for implementing intelligent interfacing functions, motor control, algorithmic acceleration and high-performance computing (HPC), image Electronica Azi International | 1/2020

and video processing, machine vision, artificial intelligence (AI), machine learning (ML), deep learning (DL), radar, beamforming, base stations, and communications. One simple example is to provide an intelligent interface between other devices that use different interface standards or communications protocols. Consider an existing system that contains an application processor connected to a camera sensor and a display device using legacy interfaces (Figure 3a). Now assume that the creators of the system wish to upgrade the camera sensor and display device to something more modern that are lighter, cheaper, and consume less power. The only problem is that one or both of these new peripherals may use a
ed to ones that require the same sequence of operations to be performed repeatedly. This is because a single processor core running a single thread can only execute one instruction at a time (Figure 4a). By comparison, multiple functions can be executing simultaneously in the FPGA, thereby allowing a series of operations to be pipelined, which in turn allows for much greater throughput. Similarly, rather than perform the same operation, say an additional 1,000 times on 1,000 pairs of data values with the processor, the same calculations could be performed in a massively parallel fashion in a single clock cycle in the FPGA by instantiating 1,000 adders in the programmable fabric (Figure 4b).
Unlike microprocessors in which only a single instruction can be executed at a time (sequentially), multiple functional blocks in an FPGA can execute at the same time (concurrently); also, FPGAs can implement appropriate algorithms in a massively parallel fashion.

modern interface standard that is not supported by the original application processor (AP). Alternatively, they may support a completely different communications protocol, like the Mobile Industry Processor Interface (MIPI). In this case, using an FPGA with its ability to support multiple I/O standards, coupled with some soft MIPI IP cores, will provide a fast, low-cost, risk-free upgrade path (Figure 3b). As another application example, consider some compute-intensive task like performing the signal processing required to implement a radar system, or the beamforming in a communications base station. Conventional processors with their von Neumann or Harvard architectures are wellsuited to certain tasks, but they are less suitwww.international.electronica-azi.ro
WHO MAKES FPGAs? This is an ever-evolving landscape. The two main manufacturers of really high-end devices with the highest capacity and performance are Intel (which acquired Altera) and Xilinx. The Intel and Xilinx offerings span the range from low-end FPGAs to high-end SoC FPGAs. Another vendor that focuses almost exclusively on FPGAs is Lattice Semiconductor, which targets lowand mid-range applications. Last but not least, Microchip Technology (via its acquisitions of Actel, Atmel, and Microsemi) now fields multiple families of small- to medium-sized FPGAs and low-end members of the SoC FPGA category. Choosing the best device for the task at hand can be tricky because there are so
many families, each offering different resources, performances, capacities, and packaging styles. Case in point, here are some examples: Intel devices; Lattice Semiconductor devices; and Xilinx devices. HOW TO DESIGN WITH FPGAs? The traditional way to design FPGAs is for engineers to use a hardware description language like Verilog or VHDL to capture the design's intent. These descriptions may first be simulated to verify they perform as required, after which they are passed to a synthesis tool that generates the configuration file used to configure (program) the FPGA. Each FPGA vendor either has its own internally developed tool chain or offers a customized version of a tool from a specialist vendor. In either case, the tools can be accessed from the FPGA vendors' websites; also, there may be free or low-cost versions of the full-blown tool suites. In order to make FPGAs more accessible to software developers, some of the FPGA vendors now offer high-level synthesis (HLS) tools. These tools interpret an algorithmic description of desired behavior captured at a high level of abstraction in C, C++, or OpenCL, and generate the input to feed the lower-level synthesis engine. For designers looking to get started, there are many development and evaluation boards available, each offering different capabilities and features. Three examples are the DFR0600 development kit from DFRobot which features a Zynq-7000 SoC FPGA from Xilinx, the DE10 Nano from Terasic Inc. which features a Cyclone V SoC FPGA from Intel, and the ICE40HX1K-STICK-EVN evaluation board which features a low-power iCE40 FPGA from Lattice Semiconductor. Designers planning on using an FPGA-based PCIe daughter card to accelerate applications running on an X86 motherboard may wish to look at something like one of the Alveo PCIe daughter cards, also from Xilinx. CONCLUSION Optimal design solutions are often provided by FPGAs, combinations of processors and FPGAs, or by FPGAs that boast hard processor cores as part of their fabric. FPGAs have evolved rapidly over the years and are able to address many design requirements in terms of flexibility, processing speed, and power, making them useful for a wide range of applications.

Interview on the new RA Family
RENESAS HAD RECENTLY ANNOUNCED THE NEW RA FAMILY. WHAT IS THE NEW FAMILY ABOUT? We had introduced in October 2019 the new RA (RA = Renesas Advanced) Family of 32-bit Arm-based MCUs. This first wave of RA MCUs comprises five different product groups in three different product series, encompassing 32 different part names total. We designed the new family to deliver the ultimate combination of optimized performance, security, connectivity, peripheral IP, and easy-to-use Flexible Software Package (FSP) needed for intelligent IoT applications. The RA Family offers industry-leading IP including Renesas’ best-in-class flash memory technology and proprietary embedded security IP. We are also announcing a new software and support strategy based around our new Flexible Software Package (FSP). WHAT MARKETS/APPLICATIONS WILL THE RA FAMILY TARGET? The RA Family and ecosystem will help customers accelerate the development of IoT endpoint and edge devices for industrial and building automation, metering, healthcare, and home appliance applications. In fact, it might be difficult to find an application field where RA Family won’t have a fitting offer.
Answers by Bernd Westhoff, Senior Manager, Microcontroller Marketing, IoT and Infrastructure Business Unit Renesas Electronics
THE RA FAMILY PROVIDES A BROAD MCU OFFER. WHAT ARE THE DIFFERENTIATING FEATURES OF THE NEW RA FAMILY MCUs? The RA Family MCUs offer a strong value proposition for customers, who are interested in a flexible open software approach that leverages the robust Arm® ecosystem. The RA family deliverables can be summarised in 4 major points: 1. Highly optimized feature set to differentiate RA MCUs against major competitors while providing the combination of Arm Cortex-M core with Renesas’ unique functionalities and market-proven peripherals from the RX and Synergy families. 2. Scalability and compatibility across the RA Family for hardware and software portability, allowing customers to build their own platform with the scalability to support a range of products now and in the future. 3. Scalable HMI solutions, including an integrated Capacitive Touch Sensing Unit for display control. Some RA MCUs offer an embedded TFT controller supported by a 2D drawing engine and JPEG engine; other MCUs include an embedded segment LCD driver. Electronica Azi International | 1/2020

4. The RA devices incorporate hardwarebased security features from simple AES acceleration to fully-integrated crypto subsystems isolated within the MCU. The Secure Crypto Engine provides symmetric and asymmetric encryption and decryption, hash functions, the latest encryption algorithms, RSA/ DSA/ ECC/AES/SHA, true random number generation (TRNG), and advanced key handling, including key generation and MCU-unique key wrapping. An access management circuit shuts down the crypto engine if the correct access protocol is not followed, and dedicated RAM ensures that plaintext keys are never exposed to any CPU or peripheral bus. ESPECIALLY THE LAST ITEM OF YOUR RA FAMILY IS OF SPECIFIC INTEREST, COULD YOU PLEASE DESCRIBE YOUR SECURITY STRATEGY A BIT MORE? The RA MCU family provides a cost-effective, scalable, and power-efficient security solution to support the needs of tomorrow’s embedded systems. Our customers can choose among many, incrementally sophisticated but easy-to-use solutions, starting with MCU devices that provide hardware acceleration for cryptographical operations, and a true random number generator. The next feature level includes systemlevel programmable MPUs to enhance security, reliability and availability of the system, and a crypto engine that shields and protects the crypto resources from malicious or unintentional usage. At the top level, TrustZone-enabled cores provide built-in isolation and security embedded at processor level. With this broad portfolio, Renesas supports customers’ security roadmaps with optimized options that meet their unique business needs. To support customers requiring specific certifications, we offered NIST and PSA Level 1 certifications already at launch time, and we will certify additional industryrecognized standards as required. WHAT SORT OF TAMPER RESISTANCE IS INCLUDED? The measures included in the RA Family MCUs are quite wide, we can basically talk about 5 different approaches to help our customers best making their design tamper resistance. 1. The RA MCUs can detect tampering attempts by monitoring dedicated pins connectable to environmental sensors or switches attached to the housing of www.international.electronica-azi.ro
the equipment. A tamper attempt triggers a timestamping of the real time clock (for logging and auditing purposes) and flag the incident to the processor in order to perform the required countermeasures. The secure crypto engine embedded in the MCU is protected by a hardware firewall enforcing execution of a Renesas pre-defined and validated sequence of commands and data inputs. Monitoring of the procedure is essential to ensure no tampering of the expected procedure takes place by means of malicious software or intrusive probing via debuggers. Only validated procedures can proceed and produce the expected outputs. Users can also lock the included Flash memory to prevent accidental or malicious modification by means of self-programming software or external agents. The debugger and factory programming interfaces can be secured against nonauthorized access or disabled before deployment in the field. Additionally, we are in the process of evaluating resistance to SPA/DPA side channel attacks, to prevent extraction of security relevant information by means of non-intrusive power and emissions analysis during chip operation.
WHAT IS THE CUSTOMER DEMAND FOR TRUSTZONE? Customers seldom ask for a specific technology; they are more interested in a solution. We see a steady, increased awareness of the critical role that security plays in embedded design and the need to consider security, strategically, from the early stages of design. TrustZone is a hardwareassisted technology included within the latest Arm MCU cores that allows customers to achieve such goals in a flexible and programmable way. Later Renesas RA CortexM33-based devices will include TrustZone. WHAT IS RENESAS’ STRATEGY FOR THE RA ECOSYSTEM? HOW WILL YOU ENGAGE WITH THIRD PARTIES? Renesas built the RA Family product line around flexibility and openness. The FSP (Flexible Software Package) is built such that developers can either leverage the out-of-box options or easily use their own resources and combine software building blocks from several providers to get to market quicker, depending on their needs and existing investments.
Renesas is heavily engaging the Arm partner ecosystem as well as key Renesas partners to develop software and hardware building blocks that will work with the RA MCUs out of the box. The RA Family ecosystem will help accelerate the development of IoT applications, including core technologies such as security, safety, connectivity, HMI, and AI among others. More than 30 partners are already and further ones will be closely integrated in early 2020 into the Renesas partner ecosystem and the building block solutions they create will have a close plug & play association to the Renesas RA family. Renesas will also tightly integrate partners and partner solutions holistically into its promotion and marketing plans with direct exposure to Renesas customers. ARE ALL RA FAMILY PRODUCTS COMPATIBLE? Yes, they are highly compatible, as they are based on the same library of our leading peripherals and IPs. Of course, we are incorporating some evolutionary upgrades on later devices. Customer designs are made easier with RA devices offering compatibility among their peripheral feature set, the pin layout between the different packages, and all this across the different MCU groups. WILL THE RA FAMILY HAVE A PRODUCT LONGEVITY PROGRAM LIKE OTHER RENESAS MCUs? With our long history enabling industries that require long and reliable device life cycles, such as industrial, healthcare, and automation, we recognize the importance role that PLP (product longevity program) plays in product design. Renesas will support the longevity program for RA MCU devices, targeting a 15-year PLP statement. WHERE DOES THE RA FIT INTO RENESAS’ MCU STRATEGY WITH SYNERGY? Renesas Synergy is a fantastic value proposition for those customers who appreciate an “off the shelf” software solution, including customers managing limited resources or specialized in-house expertise. For customers who want to utilize their existing inhouse infrastructure, the RA Family offers a flexible open software approach. Between the two solutions, Renesas enables customers across the design spectrum, offering different development options depending on the customers’ preferred approach. Thank you! 15
simpliďŹ es the implementation of audio/acoustics functions in Vehicles
By Carmelo De Mola, Manager Sales & Marketing Microchip Technology Inc; K2L GmbH & C0. KG.
In the last years the automotive industry is trying to consolidate the proliferation of the networking technologies that are used in the vehicles. The vision is to have a so called â€œmono technological networkâ€? and the solution approach is to adapt the Ethernet technology that has a proven track record in other areas to the automotive requirements. This approach solves many of the automotive networking challenges; however, it generates other challenges in certain infotainment, audio, or acoustic use-cases, just to mention some. In particular the transmission of audio signals is the big challenge and needs additional expensive hardware and software components. All these measures are complex and costly and impacts the risk, cost and time to market of the design to the negative. The new INICnet technology though offers all needed audio features such as the transfer of multiple dedicated audio and video channel in parallel with high quality of service and low latency without the need of 16
additional hardware or software. On top of that it provides also an Ethernet/IP channel enabling use-cases such as SW download (incl. Over The Air - OTA) and diagnostics plus a seamless link to the remainder of the vehicle network which is for sure Automotive Ethernet. But why do we need another open standard in the already crowded automotive standards landscape? This answer can be found by having a glance on the major challenges facing the overall automotive industry. It is struggling to become more innovative as it begins to imitate the fast-moving consumer product
lifecycles while at the same time trying to save costs. Vehicle electronics are at the heart of this. There has been a rapid rise in the amount of electronics in a typical vehicle, as can be seen in Figure 1. This growth will continue due to the three megatrends of vehicle electrification, more sophisticated driver assistance on the road to autonomous driving, and increased connectivity both within the vehicle and with other vehicles and the infrastructure. This has led to vast amounts of data being exchanged between different components inside a vehicle and between the vehicle and the infrastructure, and the numbers are only going to increase.

However, not all data exchanged in in-vehicle networks are natively available as packet data.

The implementation of this kind of application with an Ethernet network would imply the use of special standards such as Audio Video Bridging (AVB) that fulfils all requirements of audio applications such as synchronisation, low latency and reliability, but are very complex to implement in software and require high performing computing power just for handling the networking. The implementation cost of a complex software stack on a high performing microcontroller eat up all s the benefits of a network standard.
INICnet technology â€“ Ethernet coexistence. www.international.electronica-azi.ro
How to avoid that and deploy a network standard for audio, acoustics and infotainment without high implementation costs? The answer to this questions INICnet technology. INICnet technology will become an open ISO standard in 2021 and supports high quality of service audio and video channels that are completely managed through the INICnet ICs or through the available lean software, so that the engineers do not need extra development effort for handling the traffic on the network. INICnet technology provides UTP or coaxial cable as physical layers, is fully compatible with Ethernet, as each node has its own MAC address and it supports all Ethernet related mechanisms, addressing modes and packet sizes. INICnet technology is available in two different speed grades with a high bandwidth efficiency of more than 95%: 50Mbit/s or 150MB/s. Both options support ring or daisy chain. 50 Mb/s are available over UTP, 150Mbit/s are available over coaxial cable. INICnet technology supports phantom
Figure 3 power and provides a comprehensive diagnosis without the need for extra triggering cables. Figure 2 shows a typical example of how INICnet technology and an Ethernet network can coexist. The advantage of this network architecture is that the audio video applications can be based on INICnet technology as it handles audio or video data in native format; developers can concentrate on their applications without 18
caring about complex data transforming or network tasks. Another advantage is that a fast firmware update in each INICnet device could also take place over the air, as INICnet technology supports native Ethernet packets as well and is connected to the rest of the vehicle backbone over one of its devices, such as, for example, the head unit. There is no need to have a gateway application in the head unit as each INICnet device can be directly addressed by its own unique MAC address. Considering the ISO/OSI model for the , INICnet technology’s Ethernet Channel, it covers the first two layers of the model only, as can be seen in Figure 3; therefore, it can be completely abstracted from the higher layers, so that software that has been written for other technologies can be reused after a driver update. Currently there are drivers for Linux and QNX available that can be used together with the INICnet ICs and allows the INICnet technology’s Ethernet channel to be integrated into already existing IP-based system in a completely trans-
work master or network slave and can change its mode automatically if, say, after a car accident, the network is damaged, and the car user wants to perform an e-call. The network resource management and the network configuration of INICnet technology can be done by Microchip’s UNICENS unified centralised network stack. All other system management functions such as device control for example might be supported by available IP stacks such as SOME/IP stack, or any other Remote Procedure Call (RPC) techniques. UNICENS is an open source application, is available for free and lets users configure the whole network from a single device; this make it is possible to implement devices that do not need a microcontroller like microphone nodes. In case that there are nodes in the network that are only dealing with ethernet traffic like e.g. a smart antenna, this kind of nodes do not need to contain any kind of network software, or best case, if the generated data is native ethernet, it is possible to design the node without using a microcontroller in it.

OptiMOS™ Source-Down 25V power MOSFET in PQFN 3.3 × 3.3 mm package Infineon Technologies AG is focusing on system innovation with enhancements on component level by addressing the challenges of modern power management designs. The Source Down is the new industry standard packaging concept. The first wave of power MOSFETs launched in this new package is the OptiMOS™ 25V in a PQFN 3.3 × 3.3 mm. The device sets a new industry benchmark in MOSFET performance, reducing on-state resistance (RDS(on)) and offering superior thermal management capability to the marketplace. The product is well-suited for a wide range of applications such as drives, SMPS (including server, telecom, and ORing) and battery management. The new package concept connects the source potential (instead of the drain potential) to the thermal pad. Along with the enabled new PCB layout possibilities, this helps achieving ever higher power density and performance. Two different footprint versions are released – the SourceDown Standard-Gate and the Source-Down Center-Gate in a PQFN 3.3 × 3.3 mm package. The Source-Down Standard-Gate footprint is based on the current PQFN 3.3 × 3.3 mm pinout configuration. The location of the electrical connection remains the same, simplifying the drop-in replacement of
today's standard Drain-Down packages with the new Source-Down package. For the Center-Gate version, the gate-pin is moved to the center supporting easy parallel configuration of multiple MOSFETs. With its larger drain-to-source creepage distance, it is possible to connect the gates of multiple devices on a single PCB layer. In addition, moving the gate connection to the center leads to a wider source area for improved electrical connection of devices. This technology innovation results in major reduction of RDS(on) by up to 30 % compared to current technology. The thermal
resistance between junction to case (RthJC) is also significantly improved compared to the current PQFN packages. Reduced parasitics, improved PCB losses, as well as superior thermal performance, add significant value to any contemporary engineering designs. The OptiMOS™ Source-Down will be showcased at Infineon’s booth 1510 at the 2020 Applied Power Electronics Conference and Exposition (APEC), which takes place in New Orleans, LA from March 16-18. www.infineon.com/pqfn-3-source-down.

FLASH MEMORY TECHNOLOGY
Getting to market faster with modules
By Nikolai Schnarz, Product Sales Manager Professional Monitors & Applications
So-called intelligent displays already contain an integrated controller board including a graphics processor. They can thus be used without additional components such as PCs or single-board computers, both for display and device control with bidirectional communication. Especially for low or medium production volumes, they offer significant advantages over traditional displays. If all components have to be integrated individually, this takes a great deal of time and involves high development costs. The developers have to carry out every step of the design-in process themselves, from selecting suitable microcontrollers, graphics controllers and drivers, to board design, programming, testing and GUI (Graphic User Interface) development. 24
The demands placed on displays have altered dramatically. Even in industrial applications, users now expect attractive user interfaces with touchscreens and interactive displays as well as intuitive operability. Consequently, it is worth thinking about display modules.
Especially with smaller quantities, the costs and effort can quickly exceed the benefit or even the resources of a company. For example, use of a TFT display with a 4.3" diagonal (cost approx. €40) including an independent design requires the deployment of two engineers for six months. A TFT display module (cost approx. €59), on the other hand, can be integrated into an application by a developer within about a month. Thanks to reduced development costs, the overall costs are reduced in this case despite higher unit costs for the display module. As many of the time-consuming development steps are eliminated, the time-to-market is drastically reduced.
ALL-IN-ONE SOLUTION WITH CORRESPONDING SOFTWARE With its intelligent display modules, manufacturer 4D Systems offers such "one-stop" solutions for the embedded display sector. With their existing interfaces alone they enable countless extensive applications – without PC boards, which cause additional license costs for operating systems and whose functional scope exceeds requirements, especially for simple applications. For example, an intelligent display without an additional controller is sufficient for a fully-automatic coffee machine. However, if the application is to perform complex calculations with database queries, use Internet-based data streams or contain high-performance sensors or Electronica Azi International | 1/2020
DESIGN SOLUTIONS » power supplies
actuators, a single-board computer (SBC) or host controller is required. For the connection of SBCs such as Arduino, Raspberry Pi or BeagleBone Black, 4D Systems display modules offer an adapter. In addition, they are compatible with microBus (M-Bus) boards and support microelectronic compilers and microSDK as well as MPLab and Atmel Start. In order to use the display modules and create applications, 4D Systems offers the free "4D Workshop" software with four different modes: Designer mode allows 4DLG codes to be generated to program the display, while Serial mode allows the module to be converted to a slave device and controlled using any microcontroller host with a serial port. The “ViSi” and “ViSi-Genie” modes offer simplified visual programming with accompanying automatic 4DGL code generation. SEAMLESSLY SCALABLE Even after the initial creation of an application, the decision between simple displays and intelligent display modules has an effect on the development processes, because other processors are often used in new product generations. For traditional development with a chipset solution, this usually means that the GUI also needs to be adapted. In order to significantly reduce the amount of work this involves, 4D Systems has designed its development environment in such a way that the GUI is also fully supported by subsequent processors. The same applies when the production volume increases. Manufacturers then often change display suppliers – for example, because they receive more favorable conditions. This generally means, however, that the previous programming has to be adapted to the chipset of the new display. With 4D Systems display modules on the other hand, increasing production volumes without having to invest in new software development is easy. This is because both small and large order quantities are possible and the chipsets remain compatible with the existing software. STANDARD MODULES AND CUSTOMER-SPECIFIC ADAPTATION For large displays (1.38" to 7.0") – whether with or without touchscreens – 4D Systems uses TFT technology. For smaller displays without a touch function (0.96" to 1.7"), OLED technology is used because it allows a much thinner structure. The TFT displays are optionally available as open frames or with a cover glass (cover lens bezel). If the www.international.electronica-azi.ro
display is to be mounted on the inside of the housing, an open-frame version with side mounting brackets is available. If on the other hand the display is mounted on the outside, the glass frame (cover glass) model can simply be glued into the housing. All 4D Systems display modules are connected via an interface board (USB, 5V) and require a micro SD card to store the graphic content. In order to ensure the

smooth functioning of the application, especially if data from the memory needs to be processed not only temporarily but permanently, it is strongly recommended that industrial memory cards be used. These have higher-quality underlying technology and thus offer more read and write cycles than basic “consumer cards”. This increases the reliability of the entire application. Such cards can be obtained from Swissbit or Apacer, for example. With these features, the intelligent displays are particularly suitable for low-volume applications such as fully-automatic coffee machines, medical scales, dispensing sys-
The display modules are equipped with the serial interfaces I2C and SPI or RS-232 and RS-485. The standard modules, which achieve a resolution of up to 800×480 pixels, already cover a wide range of applications. In addition, 4D Systems also meets customer-specific requirements, such as a certain brightness level or the anti-reflective coating of the display, as well as specific certifications for applications in medical technology or the automotive sector.
In conjunction with other embedded and wireless products, the display modules enhance a wide range of applications, e.g. airconditioning systems with temperature displays that can also be used for touch-control.

ON Semiconductor Launches Automotive LED Drivers and Controllers for Advanced Vehicle Lighting Applications ON Semiconductor has launched a new family of four devices that facilitate the high levels of performance and innovative functionality that vehicle manufacturers and consumers now expect from automotive exterior and interior lighting. Aimed specifically at low power solid state lighting, the new family comprises two LED drivers (NCV7683 and NCV7685) and two current controllers (NCV7691 and NCV7692). In the pursuit of improved road safety, automakers are moving away from the simple ‘on/off’ operation to sophisticated systems that incorporate movement and variable intensity within rear combination lamps (RCLs), turn signals, fog lamps, and other externally modulated LED clusters to give clearer and highly visible warnings to other road users. The NCV7685 and NCV7683 integrate twelve and eight linear programmable current sources, respectively, enabling multiple strings of LEDs to be driven with up to 100 mA per channel. The
devices provide an array of configurability options, including daisy-chaining, illumination level control, current regulation,
sequencing functionality, and channel combination. The NCV7685 incorporates an 8bit I²C interface with CRC8 error detection
for individual output current adjustment via pulse width modulation (PWM), and for advanced diagnostics - including detection of an open LED string or under voltage condition – a dedicated diagnostic pin is also available. The NCV7685 may be powered with a DC-DC controller and/or LDO voltage regulator, depending upon specific design requirements. The NCV7691 provides a regulated wide current range for driving LEDs in one or multiple strings, with only an external NPN bipolar transistor and a feedback resistor. The driver provides design flexibility to add additional single channels to multichannel systems, and supports a dimming function via its PWM input. The NCV7691 includes open string, short circuit, and thermal shutdown, ensuring safe and reliable operation of essential lighting. The derivative NCV7692 offers a faster response time and a reduced threshold for open load detection. ON Semiconductor | www.onsemi.com
High efficiency: A multi-mode, forced-frequency-resonant digital controller IC for SMPS applications Infineon Technologies AG launches the XDP™ digital power XDPS21071, the first flyback controller in the industry with zerovoltage switching (ZVS) on the primary side to achieve high efficiency. This controller is aimed at fast-charging applications such as USB-PD or QuickCharge. Lightload efficiency is optimized for variable output application. The XDPS21071 is a high-performance digital flyback controller with an integrated dual-MOSFET gate driver and a 600 V depletion startup unit. The primary-side controller drives a high-voltage external MOSFET in a flyback topology and an external low-voltage MOSFET to create a pulse for achieving ZVS condition at the high-voltage MOSFET. It supports fixedfrequency switching up to 140 kHz. The patented forced-frequency-resonant (FFR) switching scheme is implemented by means of a digital algorithm, which is configwww.international.electronica-azi.ro

Miniature power supply: Infineon starts first flip-chip production specifically designed for automotive applications Infineon Technologies AG is taking the next step towards smallest power supply devices for automotive electronics. As first chipmaker, the company set up a dedicated production process for flip-chip packages that is fully aligned with the high quality requirements of the automotive market. Infineon now launches the first respective product: the linear voltage regulator OPTIREG™ TLS715B0NAV50. With flip-chip technology, the ICs are installed upside down in the package. With the heated part of the IC facing the bottom of the package and being closer to the PCB, thermal conductivity can be improved by a factor between 2 and 3. The higher power density enables a significantly smaller footprint than conventional package technologies. The footprint of Infineon's new linear voltage regulator (TSNP-7-8 package, 2.0 mm × 2.0 mm) is more than 60 percent smaller
than that of an established reference product (TSON-10 package, 3.3 mm × 3.3 mm) while the thermal resistance stays the same. This makes the new device particularly suitable for applications with very limited
board space, such as radar and cameras. The OPTIREG TLS715B0NAV50 provides 5 V with a maximum output current capability of 150 mA. Flip-chip technology has been used in con-
sumer and industrial markets for several years. Due to increasingly strict space requirements, particularly in the growing number of radar and camera systems, also automotive electronics require smaller power supply solutions – albeit with much higher quality requirements. In order to offer best-in-class flip-chip quality Infineon does not rely on a subsequent qualification of existing consumer and industrial products but rather on a dedicated production process for automotive devices. In the future, flip-chip technology will strengthen Infineon’s overall portfolio of automotive power supply products in the OPTIREG family. The chipmaker is planning to apply it also to its switch mode voltage regulators and power management ICs. www.infineon.com/tls715b0na-v50. Infineon Technologies www.infineon.com
Renesas Electronics launches industry’s first radiation hardened single-chip synchronous buck and low dropout regulator for satellite power applications Renesas Electronics Corporation announced the industry’s first single-chip synchronous buck and low dropout (LDO) regulator targeting low-power FPGAs, DDR memory and other digital loads for spaceflight payload applications. The ISL70005SEH is the only point-of-load (POL) power solution that reduces size, weight, and power (SWaP) by integrating a synch buck and LDO in one monolithic IC. The device enables satellite manufacturers to reduce bill of materials (BOM) and power supply footprint for their medium Earth orbit (MEO) and geosynchronous Earth orbit (GEO) long duration mission profiles. The ISL70005SEH rad-hard dual output POL regulator combines 95 percent high efficiency with the synch buck regulator and a low 75mV dropout on the LDO regulator. The device enables easier thermal management for systems with 3.3V or 5V power buses and can support 3A continuous output load current for the buck regulator and ±1A for the LDO. The buck regulator uses a voltage mode control architecture and switches at a resistor adjustable frequency of 100kHz to 28
1MHz, enabling a smaller filter size. The space-grade ISL70005SEH simplifies design configuration allowing designers to use it as a dual output regulator, DDR memory power solution or high efficiency low noise regulator for RF applications. The flexible LDO can source and sink current and accept input voltages as low as 775mV to reduce unnecessary power dissipation. The externally adjustable loop compensation on the buck allows users to achieve an optimal balance of stability and output
dynamic performance. The device is wafer acceptance tested to 100krad(Si) over high dose rate (HDR) and tested for ELDRS up to 75krad(Si) over low dose rate (LDR). Single event effects (SEE) testing shows no single event latch-up (SEL) and single event burnout (SEB) at a linear energy transfer (LET) up to 86MeV*cm²/mg. Single event transients (SETs) have been characterized at a LET range of 8.5 to 86MeV*cm²/mg. Renesas Electronics | www.renesas.com

Powerbox announces high peak load power supply for medical laser applications Powerbox has announced the release of its new power supply solution for high peak load applications in the medical sector. Based on digital control and high energy storage management techniques, the SMM3000A80024C series delivers 2.25kW repetitive peak power to medical lasers with high efficiency. The SMM3000A80024C complies with medical safety standards and for silent operation it includes a thermocontrolled cooling system. Laser equipment is widely used in medical applications and from cosmetic through to general surgery they all require power supplies able to deliver very high peak energy levels to the laser or discharge tubes. However, high peak energy and the repetition thereof generates electromagnetic radiation and line disturbance. This is a challenge for power designers who need power solutions that are able to deliver the required amount of power without generating line disturbances, whilst also guaranteeing patient and operator safety when high voltages and energy levels are involved during the process. CO2 (carbon dioxide) lasers or Erbium YAG are commonly used in medical applications,
though the energy released during the pulse related to the specific task can vary by large amounts. There are different types of pulsing for CO2 lasers. In the cosmetic word, there is a newer technology called UltraPulse (a very short pulse duration with high pulse power and very high influence), that is even faster than SuperPulse (medium pulse duration with medium pulse power). The power supply provides a level of protection, primary to secondary main output of
2xMOOP, and 2xMOPP to auxiliary output. To accommodate different capacitor banks and applications, the output voltage can be adjusted from zero to 800VDC (600VDC nominal) with an output current of 5.5A at nominal. An automatic current controller guarantees that the power envelope is always within safe limits, reducing capacitor aging and overstressing of components, thus contributing to a longer lifetime.

New 2x4" industrial power supplies for conduction cooling certifed to safety standard IEC/EN/UL 62368-1 With two new models BEO-0812 (+12V) and BEO-0824 (+24V) presented, the power supply specialist Bicker Elektronik (Donauwoerth/Germany) is expanding its AC/DC switching power supply series BEO by power class 80 Watt fanless for contact cooling in the space-saving form factor 2Ă—4". With forced air cooling, up to 150 Watt continuous power is available. The BEO-0800 series is also characterized by its high efficiency of up to 91% and low standby consumption <0.48 W. The rugged and reliable industrial power supplies have a wide-range input of 90 to 264 VAC with active power factor correction (PFC) for worldwide use and are certified to IEC/EN/UL62368-1. Due to the very good electromagnetic compatibility (EMC), the BEO-0800 series meets the stricter class B of EN55032. The high quality of the components used and the excellent circuit design ensure a long service life and safe 24/7 continuous operation in the extended temperature range of -20 ... +70Â°C. www.international.electronica-azi.ro
For optimum thermal connection of the power components on PCB bottom side to chassis of the application, BEO-0800 series already includes a suitable thermal pad. Due to ideal heat conduction properties and the flexible pad surface, the preassembled thermally conductive gap filler creates an optimal connection between the power components and the connected housing chassis, so that no active cooling is necessary. Due to the very good thermal
management, the heating of the switchedmode power supplies are reduced to a minimum, making maintenance-free systems without rotating fans possible. The already included insulation foil has a precisely fitting opening for the thermal pad. The BEO-0800 series combines high energy efficiency across the entire performance range with the compactness of a robust 2Ă—4" industrial PSU. The switching power supplies can be used up to an operating height of 5000 meters and have short-circuit and overcurrent protection. The insulation voltage between input and output is 4000 VDC. The space-saving BEO-0800 series is suitable for a large number of fanless industrial applications and embedded IPC systems with single voltage supply: Industry 4.0 / IIoT, automation, process measuring and control technology, energy, communication, POS / POI, digital signage, and many more.

Nexperia extends market-leading low RDS(on) MOSFET performance with the release of its 0.57 mΩ product in LFPAK56 Nexperia announced the release of its lowest-ever RDS(on) power MOSFET. Already recognised as the industry-leader in low voltage, low RDS(on) devices, the PSMNR5125YLH launched today sets a new standard of 0.57mΩ at 25V. Utilising Nexperia’s unique NextPowerS3 technology, this market-leading performance is offered without compromising other important parameters such as maximum drain current (ID(max)), Safe Operating Area (SOA) or gate charge QG. Very low RDS(on) devices are required in many applications such as ORing, hot-swap operation, synchronous rectification, motor control and battery protection, to reduce I²R losses and increase efficiency. However, some competing devices with similar RDS(on) values suffer from reduced SOA – a measure of the ruggedness of the MOSFET – and reduced ID(max)) ratings due to shrinking cell-pitches. Nexperia’s PSMNR5125YLH MOSFET offers a maximum drain current rating up to 380 Amps. This parameter is especially important in motor control applications where motor-stall can result in very high current surges for short periods,
which the MOSFET must withstand for safe and reliable operation. Some competitors provide only computed ID(max) whereas Nexperia demonstrates continuous current capability up to 380 Amps. The device is packaged in LFPAK56, Nexperia’s 5mm × 6mm Power-SO8 compatible package, offering a high performance copper-clip construction which absorbs thermal stresses, increasing quality & lifetime reliability.
Typical applications include: battery protection; brushless DC (BLDC) motor control (full bridge, 3-Phase topologies); server power for ORing, hotswap operation and synchronous rectification. More information on the new low RDS(on) MOSFETS, including product specs and datasheets is available at www.nexperia.com/nextpowers3 Nexperia | www.nexperia.com

Murata announces world’s smallest LoRa®-based module with significantly reduced current consumption Murata announces a new LoRa®-based module that, at just 10.0 mm x 8.0 mm x 1.6 mm, is the smallest available in the world today. Suitable for a wide range of highvolume applications where small size, long range, extended battery life, security and a competitive price point are requirements. Based upon a second-generation Semtech SX1262 radio frequency IC (RFIC), the Type 1SJ (https://wireless.murata.com/type-1sj.html) LoRa module also features an open STM32L0 microcontroller (MCU) from STMicroelectronics along with an RF switch and 192kB of Flash memory and 20kB of RAM. This extensive memory provision ensures that sufficient resources are available for the application layers. Also housed in the tiny module is a temperature-controlled crystal oscillator (TXCO) and multiple communication interfaces including UART / I²C / SPI / ADC / USB and various GPIOs. Designed for deployment globally, the module supports ISM bands from 868 MHz to 916 MHz, including those used in Europe, USA, India, China and the Pacific Rim. The device has a single part number globally, simplifying customer supply chains. Operating from a single supply rail (up to 3.9V DC), the Type 1SJ module incorpo-
rates several low power modes that allow the real time clock (RTC) to operate while drawing a typical current of just 1.3μA. This enhanced current consumption allows devices based upon Murata’s module to operate for years from a single battery. The open MCU allows the module to be easily flashed with code from Trusted Objects that ensures the Flash memory is secure and encrypted, protecting the end system against the ever-increasing threat
of malicious tampering. The resin mold package provides physical ruggedness, allowing the module to operate across the temperature range -40°C to +85°C. The new Type 1SJ LoRa-based module will help designers to develop solutions that meet the most demanding requirements, especially in areas such as asset tracking, utilities, agriculture, smart cities, smart buildings, industrial and other IoT applications.
