CH32V307RCT6

Overview

The CH32V305/7 is an interconnectivity MCUs 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. With single-precision float point instruction sets added and stack area extended, the CH32V305/7 features higher performance, the number of UARTs is extended to 8, and the number of motor timers is extended to 4. The CH32V305/7 provides USB2.0 high-speed interface (480Mbps), built-in PHY transceiver and Ethernet MAC upgraded to GbE, and integrates 10M PHY module.
