Aitech C925

The RTCA-compliant C925 is a low-power, rugged 3U CompactPCI PowerPC-based SBC.  The board helps significantly reduce the engineering resources typically diverted to RTCA design requirements, saving on overall system development costs. Developed specifically for avionics, the C925 is fully certifiable to both DO-178 (software) and DO-254 (hardware), making it ideal for safety and mission-critical applications, such as flight and mission control computers into FAA-controlled airspace. 

In addition to reduced design costs, the C925 saves on DO-254 certification costs by minimizing the use of on-board FPGAs. Featuring increased processing power without additional heat generation, the C925 incorporates a highly integrated PowerQUICC III 8548E processor that can be hardware configured to 1.2 GHz with a CPU core complex bus (CCB) speed of 400 MHz for maximum processing power.
