Acromag has introduced PMC (PCI mezzanine card) modules featuring the Xilinx Spartan-6 FPGA. To optimise system performance and enable cross-platform compatibility, the FPGA uses a dual-register six-input lookup table logic structure, built-in system-level blocks, and DSP slices derived from the high-end Virtex-6 architecture, says the company. Field I/O interfaces to the FPGA via the rear J4/P4 connector and with optional front mezzanine I/O extension modules. 64 I/O or 32 LVDS lines are accessible through the rear connector. The company's AXM plug-in mezzanine cards provide additional I/O processing capabilities. The mezzanine I/O cards are available to provide front-end 14bit 105MHz ADCs or an interface for CMOS digital I/O, RS-485 differential signals, or extra LVDS I/O lines. All models employ the logic-optimised SLX150 version of the FPGA which provides 147,433 logic cells and 180 DSP slices. Dual-ported SRAM of 256k or 1M x 64bit facilitates high-speed DMA transfers to the bus or CPU. This memory provides direct links from the PCI bus and to the FPGA. 16Mbyte flash memory enables on-board storage and loading of the FPGA code. The 100MHz 64bit PCI-X interface ensures fast data throughput. PMC-SLX modules are suitable for conduction-cooled systems and operate from -40 to 85°C.
