The CH32V003F4P6 from WCH (Nanjing Qinheng Microelectronics) is an industrial-grade 32-bit RISC-V microcontroller based on the QingKe V2A core with RV32EC instruction set. Operating at up to 48 MHz with 16 KB Flash and 2 KB SRAM, it provides essential peripherals including a 10-bit ADC, op-amp/comparator, DMA, USART, I2C, SPI, and multiple timers. At approximately $0.10 in bulk, it is one of the most affordable 32-bit MCUs available, ideal for cost-sensitive designs.

The CH32V003F4P6 is built around the QingKe RISC-V2A processor core implementing the RV32EC instruction set. The core features a programmable interrupt controller (PFIC) with hardware interrupt stack for fast context switching and 2-level interrupt nesting. Internal bus architecture connects the CPU to Flash, SRAM, and peripheral modules. The clock system supports internal 24 MHz RC (factory-trimmed), internal 128 KHz RC, and external crystal sources. Power management provides Sleep and Standby modes. The DMA controller with 7 channels offloads data transfer from the CPU for TIM, ADC, USART, I2C, and SPI.
