Why GD32 Is THE Motor Control MCU

Microcontrollers are a favourite product for design engineers everywhere because they can perform so many functions, and are so easy to use thanks to the familiar design environments available to program and configure them.

That do-everything capability is on full display in a brushless DC (BLDC) motor control demonstration which China-based semiconductor manufacturer GigaDevice exhibited at the Electronica India exhibition in September 2025. The ipXchange crew at the exhibition was particularly impressed because the GigaDevice GD32 MCU at the heart of the system had such a big workload:

● Not only generating the three-phase sinusoidal PWM signal controlling the current to the motor’s stators

● Not only handling sensor inputs for monitoring the position of the rotors relative to the stators

● It was also driving a display and interfacing to knobs which allow the motor to adjust the motor’s speed

So this single 32-bit MCU was controlling a sophisticated motor, providing multiple sensor interfaces and performing signal processing, and controlling the human-machine interface.

And beyond BLDC motor control, GigaDevice also offers solutions that cover a wide range of motor-drive applications, including servo and dual-servo systems, FOC motor control, floor-cleaning and vacuum motors, handheld power tools, and Wi-Fi fan control, enabling precise and efficient motor drive systems.

The GigaDevice GD32 MCU family offers designers a wide choice of performance and feature set options, and is available with various CPU cores from Arm® Cortex®-M23 and Cortex-M3 at the low end up to Cortex-M7 and RISC-V at the high end.

As the motor control demo design shows, there’s a lot that design engineers can do with a single GD32 device. And the clincher? These MCUs have highly competitive prices, and are readily available from stock at distributors around the world.
