Aitech C925 - PowerQUICCTM III 3U cPCI/CompactPCI SBC

Up to 1 GB (ECC) DDR2 RAM, PMC/XMC Slot, 2 10/100/1000 Ethernet


Aitech's C925 3U CompactPCI SBC is an evolution from the C900/C901 SBC. Modifications included a processor upgrade to the Freescale's PowerQUICC III MPC8548E – e500 System on Chip, an additional Flash memory bank, a larger nvRAM and a dual CAN bus interfaces. With the processor upgrade, the C925 has increased processing performance while maintaining or reducing the power requirements.

The MPC8548E has an on-chip 32K instruction and 32KB Data L1 caches as well as a 512KB L2 cache. The CPU speed can be configured to between 666MHz and 1.2GHz. And the CPU Core Complex Bus (CCB) can be configured to 333 or 400MHz.
