BRE440A™ Radiation Hardened Processor System on a Chip (SOC)
Overview
The BRE440A SOC CPU integrates a mix of peripheral controllers by implementing IBM’s high speed CoreConnect™ technology and contains the PPC440x5 version of the PPC440 core. The embedded processor provides high performance and low power consumption. The BRE440A SOC CPU executes at sustained speeds approaching two instructions per cycle. On-chip peripherals reduce chip count and design complexity in systems and improve system throughput. The 440 core combined with wide peripheral mix provides an ideal foundation for compact systems.
The BRE440A is the next generation of the BRE440 SOC CPU architecture which has extensive flight heritage and is currently on-orbit performing its mission on several spacecraft. This revision is designed to provide the highest level of radiation hardened processing available for spacecraft, missiles, and launch vehicles.
