RISC-V Meets 22FDX: an Open Source Ultra-low Power Microcontroller Platform

on YouTube ↗17m

" summary

An open-source PULP microcontroller is taped out in GlobalFoundries 22FDX as the Quentin chip, a 2.3 mm² die with 1.2 mm² effective logic area that combines a RISC‑V core with FPU, an efficient micro‑DMA, interleaved SRAM banks and standard‑cell memory for near‑threshold operation. Measured points: >500 MHz at 0.8 V and >350 MHz at 0.65 V, matrix multiply at ~85.5 mW and SCM‑resident code at ~5.5 mW. GF highlights 22FDX FD‑SOI body‑bias and roadmap; ecosystem shows 36 design wins, ~5 RISC‑V designs in flight.
