Busless PMC Carrier Card Allows Use of FPGA Modules in Stand-alone Mode

A busless PMC module carrier card allows use of a PMC module in an independent stand-alone mode. The APMC4110 carrier card from Acromag delivers power to a PMC module and regulates the PCI bus start-up sequence to prevent a system lock-up by the connection to the local bus. The APMC4110 is suitable for custom computing applications based on a re-configurable FPGA module operating independently of VME, CompactPCI, or other bus-level resources. With the busless carrier card, no expensive card cage or other computer chassis is required. 

The Virtex-5 FPGA modules offer plenty of computing power for engineers who would like to apply the DSP and logic capabilities without all the costly overhead of a full embedded system with a backplane, rack, CPU card and more. Acromag’s PMC-VFX module even has a hard-core PowerPC on the configurable FPGA to provide additional processing abilities for a stand-alone implementation. As a single-slot non-intelligent carrier, the board acts simply as an adapter to route signals to and from a PMC module. The user has full access to the field I/O via two 50-pin ribbon cable connectors. 

Using an external power supply, this carrier card allows use of any industry-standard PMC module. The onboard DC-DC converter creates +3.3VDC from the external +5VDC source, lowering the number of external power connections required. For troubleshooting, a 14-pin Xilinx JTAG connector facilitates boundary scan debugging. Users have access to the TDI, TDO, TCK and TMS signals. Also, a manual reset button allows the user to force a PCI reset when needed. The voltage monitor helps prevent code execution errors during power-up, power-down, or potential brown-out conditions if the +5V DC supply dips too low. Pricing starts at $275.
