SP0-S | Radiation Tolerant 3U CompactPCI SBC

NXP PowerQUICC®III MPC8548E Processor

The 3U CompactPCI SP0-S is a space-rated single-board computer (SBC), based on NXP’s PowerQUICC®III MPC8548E system on chip with an e500 processing core. The SP0-S includes several performance enhancing improvements over previous designs, including an SDRAM memory upgrade to the DDR2 with 20% higher bandwidth at lower power dissipation.

Also added are three rad-hard, 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. Fully tested and characterized to over 100 krad (Si) and latch-up immune to > 65 MeV-cm2/mg, the SP0-S is ideal for high performance high altitude, NEO, LEO and GEO missions.
