WCH(南京沁恒)China

The CH32V002 is an industrial-grade general-purpose microcontroller based on the QingKe RISC-V core, supporting a 48MHz system clock frequency. It features wide voltage operation, low-power consumption, and single-wire debugging. Its pins and functionality are compatible with the CH32V003. The CH32V002 integrates one 12-bit ADC with a sampling rate up to 3Msps. It provides seven DMA controllers, multiple timer groups, and rich peripheral resources including USARTs, I2C, and SPI interfaces.
