EPIC Expansion Card Targets PC/104 High-Voltage Apps Many high-performance, high-voltage defense applications require high-voltage relay switching as well as excellent signal isolation. To fill that need, the EPIC-footprint EPIC182 expansion card from Micro/sys targets PC/104 high-voltage applications by offering 64 lines of opto-isolated digital inputs and an additional 16 relays for isolated I/O signaling. Each of the EPIC182’s 64 isolated inputs can handle 3 VDC to 50 VDC while providing 4 kVrms isolation between the input signal and the system. A user-selectable, pull-up/pull-down resistor allows each input to be individually pulled high or low to ensure a known logic level at power-up. Sixteen lines of 1.5 kVAC isolation are available using 16 Form-C relays that also offer 250 VDC isolation between relays. The Form-C relays provide a switching capacity of 2 Amps at 30V. For improved system reliability, the relays’ current states can be read. The relays retain their states during board power-up or power-down. The EPC182 operates from a single 5V supply and draws 1.5A (max) 330 mA (typ - no relays energized). It has a flexible I/O base address range and 16-bit pass-through connector. Operating temperature range is -40° to +85°C. Price is $375 in single quantities.

Rugged, Single-Slot SBC Provides 2eSST VMEbus Performance
Dual-Core PICMG 1.3 Board Targets 32-Bit/64-Bit Computing
The SBCs used in highperformance, intensive military and aerospace applications require very high levels of performance and a lot of ruggedness. One way of achieving this is by utilizing the 2eSST protocol, which runs native on VME. The C6100 ruggedized, single-slot SBC from Aitech Defense Systems implements the 2eSST protocol by incorporating Motorola’s Tundra Tsi148 VMEbus interface chip to provide 320 Mbytes/s in most applications. The C6100’s low-power MPCC7457 G4 PowerPC processor operates at 1.276 GHz and incorporates DSP-like AltiVec technology, making the board suitable for a variety of vector processing applications. In addition, the board’s standard design enables its installation into any IEEE 1101.2 conduction-cooled VME chassis or ANSI/VITA 1-1994 standard aircooled chassis. The C6100 supports legacy MVME761 and MVME712M I/O modules and provides up to 2 Gbytes of DDR ECC-protected SDRAM and 128 Mbytes of onboard programmable user flash. Two PMC slots are provided for I/O expansion, along with two Gigabit Ethernet interfaces and two asynchronous serial ports. VxWorks and Linux RTOS are supported. Both rugged and military operating temperature ranges are available. Pricing starts at $6,750.
As 64-bit computing shifts into the mainstream, processors like AMD’s Opteron are expected to entrench themselves as forces to be reckoned with. But 32-bit technology must also be accommodated. The full-size PICMG 1.3 MB-06049 system host board from WIN Enterprises is powered by AMD’s Opteron processor and enables both 32-bit and 64-bit computing. The MB-06049 PICMG 1.3 supports either a single- or dual-core CPU, and a full range of Opteron processors, from low to high power. A HyperTransport interconnect system enables quad-core designs by allowing the additional integration of one or two dual-core processors on stackable boards. The MB-06049 includes the NVIDIA nForce Professional 2200 chipset. A 20-lane PCI Express slot is also featured. The board includes two memory slots totaling up to 8 Gbytes. Two additional memory slots with an optional CPU adapter card yield a total of 16 Gbytes. Interfaces include standard IDE, 4X SATA with RAID, 1 Gigabit Ethernet and four USB 2.0. The MB-06049 supports Linux Debian 64 and Windows XP 32- and 64bit operating systems. Evaluation products are available now with production volumes in January 2006. Without CPU or memory, prices are $1,000 for the single-processor version and $1,200 for the dual-processor version.

Single PMC Board Is Quad Port SAS Disk Controller The SAS drive controllers used in storage systems for military applications—such as distributed computing, video-on-demand or image/signal processing—deliver data transfer rates of up to 3 Gbits/s per interface while leveraging existing SCSI protocols. One of the first quad port SAS disk controllers on a single PMC board is the SC PMC/SA1 from Concurrent Technologies. The SC PMC/SA1 provides four independent SAS and/or SATA ports utilizing the LSI Logic LSISAS1064 serial drive controller. The board can support serial link connections for up to four SAS 1.0- or four SATA 1.0a-compatible HDD, or a combination of both interfaces. Each link operates at either 1.5 Gbits/s or 3 Gbits/ s. All serial attached device protocols, such as SSP, SMP, STP and SATA, are supported, as well as 2-, 3- and 4-lane SAS wide port configurations. The board’s PMC PCI interface supports 32/64-bit 33/66 MHz PCI buses and 3.3V PCI signaling. Two Mbytes of flash EPROM are pre-programmed with the LSI PC BIOS and onboard configuration utility, and 32 Kbytes of NVRAM are provided for configuration data and nonvolatile RAID information. Linux, Windows 2000, Windows Server 2003 and Windows XP are supported. List price is $790.
