WCH CH32V205 is a 32-bit RISC-V MCU clocked at up to 192 MHz with 32KB SRAM, 256KB flash, and a USB 2.0 high-speed Host/device interface with a 480 Mbps PHY.
The new microcontroller also features another USB 2.0 full speed (12 Mbps) Host/Device interface, a USB PD port, eighty GPIOs, a 16-channel 12-bit ADC, a 16-channel touchkey interface, and other interfaces such as CAN Bus, USART, I2C, SPI, and QSPI.
The CH32V205 appears to build upon the earlier CH32V203, but offers more GPIO, a 480 Mbps USB HS port, and USB-C PD support, and other changes. As a side note, if you’d rather get a more powerful RISC-V MCU with a USB 3.0 interface, then the WCH CH32H417 might be worth a look.
The English versions of the CH32V205 datasheet and reference manual can be found on the download page, but for C code samples (CH32V205EVT.ZIP), you currently need to head over to the download page in Chinese. Development can be done through the MoonRiver IDE, but CNLohr’s GCC toolchain (CH32fun) might soon support the new RISC-V microcontroller, since CH32V203 and CH32V208 are already supported.
