GigaDevice has launched the GD32M531 series 32-bit MCUs built on an Arm Cortex-M33 core running at up to 180 MHz, with integrated hardware accelerators for trigonometric functions and SVPWM to support field-oriented control (FOC) algorithms across dual motors plus PFC.
The devices include 256KB Flash, 64KB Data-Flash, 32KB SRAM (both with ECC), two enhanced AD-Timers with hardware phase-shifted ADC trigger linkage, and microsecond-level overcurrent protection via an integrated POC>OC block. Operating from 2.7V–5.5V across –40°C to 105°C (junction to 125°C), the GD32M531 is available in LQFP48 and LQFP64 packages, with samples available now and mass production beginning in April 2026.
