Aitech's SP0 3U CompactPCI SBC is an evolution from the Aitech C925/S950 SBCs. Modifications included a processor upgrade to the Freescale's PowerQUICC III MPC8548E – e500 System on Chip, an additional large user Flash. With the processor upgrade, the SP0 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 833MHz and 1.166GHz. And the CPU Core Complex Bus (CCB) is configured to 333 MHz.
For systems requiring maximum processing power, the SP0 processor can be configured to 1.17 GHz with CCB speed of 333.3MHz.
The SP0 backplane connections were designed such that the SP0 can be configured as a one-to-one drop in replacement for the S950.
The SP0 implements large on-board memory size to support the processor and user application needs. Memory resources include up to 512 MB fast DDR1 (Double Data Rate) SDRAM with ECC protection, 1GB User Flash, 512 KB redundant Boot Flash.
Onboard I/O capabilities of the SP0 include two (2) Gigabit Ethernet ports, four (4) high-speed serial communications ports and up to five (5) general-purpose discrete I/O channels. To further expand its capabilities, the SP0 is equipped with an industry standard air- or conduction-cooled PMC slot allowing for installation of additional modules and functionality.
The SP0 may perform as either the CompactPCI system controller or as a peripheral board. When configured as system controller, the SP0 can support up to eight (8) additional cards on the CompactPCI backplane, providing clock, and arbitration and interrupt capabilities.
The highly integrated design of the SP0 guarantees performance and versatility for conduction- or air-cooled CompactPCI SBC aerospace applications
