BRE440 RadHard CPU

Next Generation Spacecraft Processor

The Broad Reach Engineering BRE440 CPU is designed to meet the requirements of a wide variety of current and future space and high reliability applications. The BRE440 CPU is a fully radiation hardened implementation of the PowerPC 440 processor core in a true System-On-a-Chip design, including floating point unit.

Broad Reach Engineering has licensed the PPC440 core from IBM and has integrated it into the in-house developed chip design. Broad Reach Engineering has contracted with Synopsys and Honeywell for the final implementation and manufacture of the devices.

The BRE440 Chip presents the culmination of several years of internal development effort aimed at producing the highest level of space based processing capabilities.
