S740 | Radiation Tolerant Communications PMC

Aitech’s S740 Communications PMC is a single width, conduction-cooled PCI mezzanine card (PMC) designed and characterized primarily for space applications. The board features 16 RS-422 differential inputs and 16 RS-422 differential outputs with onboard FPGA logic to interface to the external spacecraft sensors and devices.

The S740 has an onboard PCI Bus DMA controller to move data to/from system buffers and the local onboard SDRAM buffers. An additional DMA controller moves data to/from the SDRAM buffers to/from the serial I/O ports. Output data packets are automatically sent out from the on board buffers and incoming data packets are stored on board until a programmable packet size is received and the local DMA controller then transfers received data to global memory across the PCI bus.
