Manufacturer: Aitech

Aitech's C901 3U CompactPCI SBC is one cornerstone of the C90x product family and represents an evolutionary development of the groundbreaking C900. By upgrading the PowerPC processor to Freescale's new 7448, Aitech has increased processing performance while maintaining modest power requirements. Other hardware compatible C90x variants include the C900 and the low power C903.

The next generation Freescale 7448 PowerPC processor has doubled the size of on-chip L2 cache to 1 MB compared to the 7447A and raised the speed of the CPU and memory buses to 166 MHz. At the same time, core voltage has been reduced, and the Dynamic Frequency Switching mechanism has enhanced, to minimize power dissipation, and enable power saving when demands are low. 

In the low power C901L configuration, with the processor operating at 1.0 GHz, the performance can exceed that of the 7447A-based C900 while power consumption is actually lower.

And for systems requiring maximum processing power, the standard configuration C901, the processor operating at 1.4 GHz, provides the best power per performance of any rugged 3U CompactPCI PowerPC SBC available. Since the C901/C901L are one to one drop-in replacements for the C900, all systems currently using the C900 can benefit from a C901 upgrade without any modification whatsoever.
