Overview
The CH32F205/7 is an industrial-grade interconnectivity MCU based on the Cortex-M3 core. The system clock frequency can be up to 144MHz, and GPIO is supplied independently (separated from the system power supply). Compared with CH32F103, CH32F205/7 has an additional random number unit and 4 operational amplifier comparators. The number of UARTs is increased to 8, and the number of motor timers is increased to 4. CH32F205/7 provides clock security system, power management, dual DMA, DAC, SDIO, CAN, FSMC and other resources. CH32F205/7 also provides USB2.0 high-speed interface (480Mbps) with built-in PHY transceiver, and Ethernet MAC upgraded to Gigabit with integrated 10M PHY module.
