GD32M531

Overview

High‑Performance Computing

Cortex®‑M33 core @ 180 MHz with DSP extension and FPU
CPU performance: 705 CoreMark, 267 DMIPS
Hardware accelerators: Trigonometric Math Unit (TMU) + Space Vector Pulse Width Modulation (SVPWM)
Rich Analog Integration for Motor Drive

2 ADC units supporting independent or synchronous sampling
3 dedicated channels with individual sample‑and‑hold, up to 5 simultaneous sampled signals
4 nested conversion sequence groups per ADC
2 DAC channels and 4 comparators; DAC can serve as negative reference input for comparators (COMP) or debug output
Advanced Digital Motor Drive Integration

2 enhanced advanced timers supporting dual‑motor Field‑Oriented Control (FOC)
4 general‑purpose timers optimized for Interleaved‑PFC control
Hardware shutdown with filtered overcurrent protection (OCP), no CPU intervention required
Hardware phase shift + dual‑point ADC trigger, supporting single‑shunt current sensing
Industrial‑Grade Safety & Reliability

Full‑region ECC for Flash and SRAM
Compliant with UL/IEC 60730 Class‑B functional safety standards
Enhanced ESD performance: HBM ±4 kV, CDM ±1 kV; latch‑up immunity ±200 mA at 125℃
