Aitech C903 - Low PowerPC® 750FL at 600Mhz cPCI/CompactPCI SBC

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


Aitech’s C903 is the low power entry in the C90x rugged 3U CompactPCI SBC product family. Powered by IBM’s advanced 750FL low power PowerPC® microprocessor with its large integrated on-chip L1 and L2 cache, the C903 provides impressive computing power. Other hardware compatible C90x 3U SBCs are available, providing various levels of performance and power consumption. To ensure high reliability under extreme operating conditions the C903 is capable of accurate temperature self-monitoring and power dissipation control through on-board temperature sensors.

The C903 implements large on-board memory arrays to support the processor and user application needs. Memory resources include up to 1 GB fast DDR (Double Data Rate) SDRAM with ECC protection, 128 MB User Flash, 64 MB Boot Flash, up to 2 GB Flash File (NAND Flash) and 128 KB NVRAM for user/application specific parameter storage.

In addition to its high performance processor architecture, the C903 provides a variety of I/O capabilities integrated on board. I/O interfaces include two Gigabit Ethernet ports, two high-speed serial communications ports, two USB 2.0 ports, and up to eight general-purpose discrete I/O channels. To further expand its capabilities, the C903 is equipped with an industry standard PMC slot allowing for installation of additional modules and functionality.

The C903 may perform as either the CompactPCI system controller or as a peripheral board. When configured as system controller, the C903 can support up to six additional cards on the CompactPCI backplane, providing clock, arbitration and interrupt capabilities. 

The highly integrated design of the C903 guarantees outstanding low power performance and versatility for a rugged conduction or air-cooled PowerPC 3U CompactPCI SBC.
