Microchip Technology, Inc. Rad-Hard Arm® Cortex®-M7 Microcontroller SAMRH707

The SAMRH707 is a radiation hardened microcontroller (MCU) providing the best combination of space connectivity interfaces along with high processing power up to 100 DMips ( >5 Coremark/MHz ). The SAMRH707 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 and CAN FD and advanced analog functions with 12-bit ADC and DAC.
