The RAD5545™ SpaceVPX single-board computer (SBC) integrates the version 1.2 RAD5545 system-on-chip (SoC) processor with volatile and nonvolatile memory on a 6U-220 format module compliant to the ANSI/VITA 78.00 SpaceVPX standard.

The SBC is designed to support operation as either a payload or system controller in a SpaceVPX backplane. Based on BAE Systems’ RAD5545 or RAD5515 QorIQ® Power Architecture® radiation-hardened SoC processor, the SBC offers both high performance and high I/O throughput

It includes 4 GB of DDR3 SDRAM with error correction at 800 MTransfers/ second and 1 GBytes of triple modular redundant non-volatile flash memory and optional 4MB MRAM. Up to four RapidIO ports at 10 Gb/second each and 12 SpaceWire links at 320 Mb/second each are provided to the SpaceVPX backplane. An optional daughter card with PCI, RapidIO, and/ or SpaceWire interfaces can be used to tailor the SBC to custom needs.
