CH32V003F4U6

WCH

CH32V003F4U6 is a WCH QingKe RISC-V2A microcontroller in QFN-20 (3 × 3 mm) — for ultra-compact, cost-sensitive control designs such as small appliances, sensor nodes and interface converters. It runs at up to 48 MHz with 16 KB Flash, 2 KB SRAM, a 10-bit ADC, USART/I²C/SPI and single-wire debug, from 2.7 to 5.5 V. Selection advice: choose this QFN-20 code over the TSSOP-20 CH32V003F4P6 when board area is tight — the peripherals are the same, but the 0.4 mm-pitch QFN footprint and assembly process differ, so the two are not drop-in substitutes. Package verified against the WCH CH32V003 datasheet CH32V003DS0, Chapter 4 ordering table.
