Overview
The GD32E232 series MCU is based on the Arm® Cortex®-M23 core operating at up to 72 MHz and supports up to 64 KB of embedded Flash memory and 8 KB of SRAM.
The series integrates five 16-bit general-purpose timers, one 32-bit general-purpose timer, one 16-bit advanced timer, and 2×16-bit basic timers. It provides a rich set of communication interfaces, including two USARTs, two I2Cs, two SPIs, and one I2S.
The series also integrates analog peripherals including one ADC and four DACs.
