The Aitech SP0-S is a space-qualified Radiation Tolerant 3U CompactPCI single-board computer (SBC) designed for LEO, MEO, and GEO missions. The SBC is based on NXP’s PowerQUICC®III MPC8548E system on chip (SoC) with an e500 processing core. It also consists of three radiation hardened on-board temperature sensors as well as six microcontroller-based A/Ds that monitor the board’s 3.3 VDC input voltage and five of the internally generated CPU core and I/O voltages.
