Radiation-hardened SAMRH71 MCUs for space systems
Summary
To enable system designers better integration and higher performance while reducing development costs and time to market, COTS technologies and scalable solutions are increasingly used in space applications. “The introduction of Arm technologies for space applications opens up new perspectives by enabling the use of the same ecosystem well in place in the consumer and industrial sectors,” said David Dangla, VLSI Components Expert at CNES. Designed for high-level radiation performance, extreme temperatures and high reliability, the SAMRH71’s Arm Cortex-M7 core is coupled with high-bandwidth communication interfaces such as SpaceWire, MIL-STD-1553, CAN FD and Ethernet with IEEE 1588 Generalised Precision Time Protocol (gPTP) capabilities. The device is fully ESCC qualified with support from CNES and compliant with MIL standard Class V and Q high-reliability grades, allowing systems to meet strict compliance requirements. Extending the portfolio of Microchip’s radiation-hardened Arm Cortex-M7-based MCUs, the SAMRH707 device provides analog functions on top of a >100 DMIPS processor unit with Digital Signal Processing (DSP) capabilities, combined with space connectivity interfaces in a small footprint designed for high-level radiation performance, extreme temperatures and high reliability.
