CH32V303VCT6

Overview

The CH32V303 series is an industrial-grade general-purpose microcontroller designed based on 32-bit RISC-V. It is equipped with a hardware stack area and fast interrupt entry, which greatly improves the interrupt response speed based on standard RISC-V. The CH32V303 series is equipped with V4F core. Add a single-precision floating-point instruction set, expand the stack area, have higher computing performance, expand the number of serial port UARTs to 8 groups, and motor timers to 4 groups.
