CH32V003A4M6
WCHCH32V003A4M6 is a WCH QingKe RISC-V2A microcontroller in SOP-16 — for simple control and sensing designs that do not need the full I/O count of the 20-pin variants. It runs at up to 48 MHz with 16 KB Flash and 2 KB SRAM, but the 16-pin package brings out 14 I/O and 6 ADC channels against 18 I/O and 8 channels on the TSSOP-20/QFN-20 codes. Selection advice: check your pin budget first — firmware is shared across the CH32V003 family, yet designs using the top ADC channels or GPIOs of the F4P6/F4U6 will not port to this package unchanged. Package and pin-count differences verified against the WCH CH32V003 datasheet CH32V003DS0, model table and Chapter 4.
