WCH has released the CH32V205, a 32-bit RISC-V microcontroller running at up to 192 MHz with 32KB SRAM and 256KB flash. Its standout feature is a USB 2.0 high-speed interface with a 480 Mbps PHY, alongside a full-speed USB 2.0 port, USB-C PD support, 80 GPIOs, a 16-channel 12-bit ADC, touchkey interface, and connectivity options including CAN Bus, USART, I2C, SPI, and QSPI. It builds on the earlier CH32V203 with expanded GPIO, faster USB, and USB-C PD. English datasheets are available, and development can be done via MoonRiver IDE or the CH32fun GCC toolchain, which may soon add support for this new MCU.
