Overview: CH32F20x Datasheet
For CH32F203/205/207/208xx V2.3
Overview
The CH32F2x series are industrial-grade general-purpose microcontrollers based on 32-bit ARM Râ—‹ CortexTM-M3 core. The clock speed can be 144MHz. GPIO is supplied independently (separate from system power supply). Sources added: Random Number Generator, 4 Operational amplifiers, TouchKey detection, USART/UART increased to 8, Motor timers increased to 4, and an expanded 32-bit general-purpose timer. Dedicated interfaces: USB2.0 high-speed interface (480Mbps) with built-in PHY transceiver, Ethernet MAC that reaches gigabit, integrated 10M-PHY module. It supports BLE5.3. The CH32F2x is equipped with multiple sources, such as clock security, power management, dual DMA, ADC, DAC, SPI, I2C, DVP, SDIO, CAN, FSMC and so on. It can be applied to prehensive application scenarios of multi-collection and multi-munication directions.
