Aitech's C901 3U CompactPCI SBC represents an evolutionary development of the ground breaking C900. By upgrading the PowerPC processor to Freescale's new 7448, Aitech has increased processing performance while maintaining modest power requirements.
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 166MHz. 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.
The C901 is available with three different versions of the MPC7448 processor operating at three different frequencies. The standard C901 operates at 1.4GHz and offers the highest performance, while the ultralow power C901U operates at 600MHz and consumes just half the power.
As the C901 is a one to one drop in replacement for the C900, all systems currently using the C900 can benefit from a C901 upgrade without any modification whatsoever.
The C901 implements large on-board memory arrays to support the processor and user application needs. Memory resources include up to 1 GB fast DDR333 (Double Data Rate) SDRAM with ECC protection,
128MB User Flash, 64MB Boot Flash, up to 16 GB Flash File (NAND Flash) and 128kB NVRAM for user/application specific parameter storage. C901 onboard I/O capabilities 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 Aitech capabilities, the C901 is equipped with an industry standard PMC slot allowing for installation of additional modules and functionality.
The C901 may perform as either the CompactPCI system controller or as a peripheral board. When configured as system controller, the C901 can support up to six additional cards on the CompactPCI backplane, providing clock, arbitration and interrupt capabilities. The highly integrated design of the C901 guarantees unmatched performance and versatility for a rugged conduction or air-cooled PowerPC 3U CompactPCI SBC.
