What the CH32V003 does
The CH32V003x series are industrial-grade microcontrollers based on the Qingke RISC-V V2A core, operating at 48 MHz with 3.3V or 5V supply. These devices feature 16KB CodeFlash, 2KB SRAM, a 10-bit ADC, seven DMA channels, and standard interfaces including USART, I2C, and SPI. Available in SOP, TSSOP, and QFN packages, they support temperatures from -40°C to 85°C. The family includes variants like the CH32V003F4P6, F4U6, A4M6, and J4M6, which differ in pin count and I/O availability. Designed for embedded control, these MCUs integrate a hardware interrupt controller, multiple timers for PWM generation, and a unique 96-bit ID for security applications.
