Overview
The Microchip PolarFire SoC MPFS250T is a mid-range SoC FPGA that combines a flash-based FPGA fabric of 254,000 logic elements with a five-core 64-bit RISC-V CPU subsystem — one E51 monitor core plus four coherent U54 application cores with a 2 MB L2 cache.
Because the configuration fabric is flash-based rather than SRAM-based, the device is immune to single-event upsets in its configuration memory and needs no external configuration PROM, which simplifies board design and improves boot reliability in industrial and defence equipment.
The 250T is the largest device in the current MPFS family line-up and is supplied in a 1152-ball FCBGA for full I/O and SerDes access, or a 536-ball FCSG package for compact designs. Microchip's PolarFire SoC ecosystem (Icicle Kit, Video Kit, Discovery Kit) provides reference hardware for bring-up.
Key Benefits
Deterministic RISC-V CPU cluster tightly coupled to the fabric, SEU-immune flash configuration, DPA-resistant security with a physically unclonable function, and up to 4 SerDes lanes at 12.7 Gbps for mid-range line-rate protocols.
Applications
Industrial motor and servo control, secure networking and TSN endpoints, machine-vision pre-processing, defence and avionics compute, space-adjacent payloads, and functional-safety platforms needing RISC-V determinism.
