10-cent WCH CH570/CH572 RISC-V MCU features 2.4GHz wireless, Bluetooth LE 5.0, USB 2.0

CH572 development board

Patrick Yang, CTO at WCH, has recently unveiled the CH570 RISC-V SoC with 2.4GHz wireless and USB 2.0 (host & device) as an upgrade to the popular CH32V003 general-purpose RISC-V MCU with more features at the same low price (10 cents). CH570 also comes with 12KB SRAM and 256KB flash (vs 2KB SRAM and 16KB flash for the CH32V003), offers up to twelve GPIO,  six PWM, I2C, UART, SPI, and a 20-channel key detection module. There’s also the CH572 with the same features, except it also supports Bluetooth LE 5.0. As a side note, I wrote about the CH572 RISC-V MCU with BLE in 2019, but I guess it was scraped likely because it had OTP instead of flash…, and the new CH572 (2025) is different. WCH CH570/CH572 specifications:  CPU core QingKe 32-bit RISC-V3C core @ up to 100 MHz (RV32IMBC instruction set and custom instructions) Low-power 3-stage pipeline High-speed […]
