Microchip Announces PIC64-HPSC Space Computing Milestones, Demonstrating Radiation-Tolerance Progress For Mission-Critical Space Systems

As civil, commercial, scientific and defense spacecraft become more autonomous, software-defined and data intensive, mission developers need substantially greater onboard processing capability, combined with the resilience, security and reliability required for demanding space environments. Microchip Technology (NASDAQ:MCHP) today announces several important milestones for its PIC64-HPSC High-Performance Spaceflight Computing Series, a 64-bit multicore RISC-V computing platform designed specifically for spacecraft, satellites and other mission-critical space systems.

Early radiation characterization of the PIC64-HPSC1000-RH radiation-hardened variant has demonstrated Total Ionizing Dose (TID) performance to 200 krad(Si) and successful Single Event Latch-up (SEL) testing to 78.2 MeV·cm²/mg under specified operating conditions. Early testing also demonstrated robust system-controller operation during Single Event Effects (SEE) characterization, with no uncorrected errors or external resets required during the testing completed to date. These results provide developers with tangible evidence of the platform’s progress toward meeting radiation-tolerance requirements, helping enable future spaceflight systems from Low Earth Orbit to the Moon, Mars and beyond.
