Device Overview

Summary

The SAMRH71 is a radiation hardened microcontroller (MCU) providing the best combination of space connectivity interfaces along with high processing power up to 200 DMips ( >5 Coremark/MHz ). The SAMRH71 is designed for high level radiation performances, extreme temperature and high reliability in aerospace application. It takes advantage of the powerful ARM Cortex M7 coupled with high bandwidth communication interfaces such as SpaceWire, MIL-STD-1553, CAN FD and Ethernet with TSN capabilities.

Easy evaluation with the SAMRH71F20-EK hardware development platform 

Supported by MPLAB X IDE and MPLAB Harmony.
