CH32V203C8T6 LQFP48 144MHZ RISC-V industrial-grade microcontroller
Description
CH32V203C8T6 LQFP48 144MHZ RISC-V industrial-grade microcontroller
Overview
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 49.3uA/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.

Software Development Tools
MounRiver Studio IDE
The Eclipse-based closed-source MounRiver Studio IDE is the official development environment provided by WCH. It supports Windows, Linux, and Mac. MounRiver Studio can be downloaded for free.
Open-Source GCC Toolchain
You can download a complete toolchain (GCC and OpenOCD) for Linux and Mac from the MounRiver Studio website. However, on Linux you can also install a GCC-based toolchain by running the following command:
sudo apt install build-essential libnewlib-dev gcc-riscv64-unknown-elf
Arduino IDE and PlatformIO Support
There are projects around to make the CH32V203 compatible with the Arduino IDE (arduino_core_ch32) and PlatformIO (platform-ch32v).
