CH32V003A4M6 RISC-V - Microcontroller IC 32-Bit 48MHz 16KB (16K x 8) FLASH,
20-TSSOP
Overview
The CH32V003 series is an industrial-grade general-purpose microcontroller based on the QingKe RISC-V2A core, supporting a 48MHz system clock frequency. It features wide voltage operation, 1-wire debugging, low-power consumption, and ultra-compact packaging. It provides commonly used peripheral functions, including one DMA controller, 1×10-bit ADC, 1 OPA, multiple timer units, and standard communication interfaces such as USART, I2C, and SPI. The product operates at a rated voltage of 3.3V or 5V within an industrial-grade temperature range of -40°C to 85°C.
