Radiation-hardened Arm Core MCUs open up space applications
Based on the automotive-qualified SAMV71, the SAMV71Q21RT radiation-tolerant and SAMRH71 radiation-hardened MCUs implement the widely deployed Arm Cortex-M7 System on Chip (SoC), enabling more integration, cost reduction and higher performance in space systems. The SAMV71Q21RT and SAMRH71 allow software developers to begin implementation with the SAMV71 COTS device before moving to a space-grade component, significantly reducing development time and cost. Both devices can use the SAMV71’s full software development toolchain, as they share the same ecosystem including software libraries, Board Support Package (BSP) and Operating System (OS) first level of porting. Once preliminary developments are complete on the COTS device, all software development can be easily swapped out to a radiation-tolerant or radiation-hardened version in a high-reliability plastic package or space-grade ceramic package. The SAMV71Q21RT radiation-tolerant MCU reuses the full COTS mask set and offers pinout compatibility, making the transition from COTS to qualified space parts immediate.
While the SAMV71Q21RT’s radiation performance is suitable for NewSpace applications such as Low Earth Orbit (LEO) satellite constellations and robotics, the SAMRH71 offers the radiation performance suited for more critical sub-systems like gyroscopes and star tracker equipment.
