Overview
The CH32V208 is a wireless MCU based on 32-bit RISC-V core, with hardware stack area and fast interrupt entry. Compared with standard RISC-V, the interrupt response speed is greatly improved. The CH32V208 is based on V4C core. The memory protection unit is added and hardware division cycle is reduced. The CH32V208 integrates 2Mbps BLE communication module, 10M Ethernet module (MAC+PHY), USB2.0 full-speed device and host/device interface, CAN controller, etc.
