From its PolarFire brand, the parts are the MPF050T FPGA and MPFS025T SoC, both available in 11 x 11mm packaging.

“We have reduced power consumption by up to 50% or more with the introduction of lower density offerings, while maintaining capabilities on these platforms,” said Microchip FPGA v-p Bruce Weyer.

The SoC version has FPGA plus processing hardware, in this case an “application class Risc-V architecture-based processor complex with 2Mbyte of L2 cache and LPDDR4 memory support”, said Microchip. “Extending the portfolio with a 25k logic elements multi-core RISC-V SoC and a 50k logic elements FPGA opens new application possibilities. They are ideal for low-power smart embedded vision applications and thermally constrained automotive, industrial automation, communications, defence and IoT systems.

Volume shipment of production silicon is scheduled for the first calendar quarter of 2022, but developers can get going with the company’s recently released Libero 2021.2 software tools, available from its website.
