Description
The CH32V203 is an industrial-grade enhanced low-power general-purpose MCU based on 32-bit RISC-V core. The CH32V203 features high performance, and supports up to 144MHz system clock frequency. The operating power consumption can be as low as 45uA/MHz. CH32V203 integrates 2-channel USB interface which supports USB Host and USB Device functions. The CH32V203 provides 1-channel CAN interface (2.0B active), 2-channel OPA, 4 UARTs, 2 IICs, 12-bit ADC, 10-channel TouchKey and other peripheral resources. Several packages such as TSSOP20, QFN28 QFN48, LQFP32 and LQFP48 are available for users.
CH32V20x chip can be programmed using the MounRiver IDE and compiler, with the option of using the on-board or independent WCH-Link for debug and download.
