Radiation-Tolerant PolarFire® SoC FPGAs

First RISC-V® Based, Radiation-Tolerant System-on-Chip (SoC) FPGA


Our radiation-tolerant PolarFire® SoC FPGA is the industry’s first embedded, real-time, Linux®-capable, RISC-V-based Microprocessor Subsystem (MSS) on the flight-proven, radiation-tolerant PolarFire FPGA fabric. Unlike SRAM-based alternatives, these devices bring low power consumption and zero configuration upsets to embedded systems. These devices are supported by our extensive Mi-V ecosystem for RISC-V-based solution stack development.

The RTPF500ZT RT PolarFire FPGA is now QML Class Q qualified, offering low-power, radiation-tolerant performance with no configuration upsets to meet the requirements of mission-critical space systems. Engineering samples of the RT PolarFire SoC FPGA, integrating a RISC-V® processor with proven FPGA fabric, are also available for advanced payload and avionics development. To learn more, contact a Microchip sales representative or authorized worldwide distributor.
