Proton and Heavy-Ion Characterizations on Microchip PolarFire® SoC FPGA Microprocessor Subsystem

This paper presents the initial findings of heavy ion and proton effects on the PolarFire SoC RISC-V® FPGA Micro-processor Subsystem (MSS) utilizing SiFive architecture. The results indicate the feasibility of deploying the PolarFire SoC RISC-V FPGA MSS in space, demonstrating suitability for both Low Earth Orbit (LEO) and Geostationary Earth Orbit (GEO) applications. Better MSS radiation performance is expected in the RT (Radiation-Tolerant) PolarFire SoC FPGA.
