Overview

The GD32M531 series is a 32-bit MCU family purpose-built for motor control applications. It features a 180 MHz Arm^® Cortex^®-M33 core with DSP extension and FPU, delivering 705 CoreMark^® and 267 DMIPS. The device integrates 256 KB Flash, 64 KB Data-Flash, and 32 KB SRAM, all with full-region ECC error correction.

Built-in dedicated motor control hardware accelerators enable independent dual FOC driving, while integrated POC&GTOC provides microsecond-level overcurrent protection. The device operates from 2.7 V to 5.5 V over a temperature range of -40°C to 105°C, and is UL/IEC 60730 Class B certified. With highly integrated peripherals to simplify system design, the GD32M531 supports precise dual-motor plus PFC control, making it widely suitable for motor control in home appliances and industrial scenarios.
