Introduction

Aitech's C920 3U CompactPCI SBC is an ultra-low-power, high-performance PowerPC® platform packed into a small 3U form factor. Based on Freescale's MPC8349E PowerQUICCTM II Pro controller the C920 SBC features a combination of the advanced e300 PowerPC core and multiple I/O interfaces integrated into a single low power device. The C920 implements high capacity high-speed memory arrays to support the processor capabilities and user application needs. Memory resources include 256 MB fast DDR2 266 (Double Data Rate II) SDRAM with ECC protection. Non-volatile memory arrays include 128 MB Boot Flash, 384 MB User Flash memory for application software, mass storage, etc., and 512 kB MRAM (NVRAM) for user/application-specific parameter storage.

The C920 onboard I/O capabilities include two Fast Ethernet ports, one UART serial communication port and up to twenty-one general-purpose discrete I/O channels. To further expand its capabilities, the C920 is equipped with a standard PMC slot allowing for installation of additional modules and functionality.

The C920 may perform only as CompactPCI system slot SBC supporting up to four CompactPCI peripheral boards providing clock and arbitration services.

The C920 was designed and tested for the most rugged conduction or air-cooled environments.
