en.Wedoany.com Reported - China's Geehy Semiconductor launched the G32F031 motor control MCU on May 14, 2026. This is the first product of its G32F0 platform, targeting the motor drive industry's demand for high energy efficiency and low cost. The chip is based on the Arm Cortex-M0+ core, with a main frequency of 64MHz, supports a wide voltage supply range from 1.8V to 5.5V, integrates 64KB Flash and 8KB SRAM, and features built-in DIV/MULT/CRC algorithm acceleration units. It supports sensored/sensorless FOC vector control, offering improved computational efficiency compared to standard MCUs.
The G32F0 platform is designed with enhanced system capabilities and computational performance, along with enriched peripheral configurations, aiming to help customers simplify hardware design. As the debut product, the G32F031 integrates a one-stop analog peripheral signal processing system: it includes one 12-bit ADC (maximum sampling rate 2MSPS), supporting 8 independent result registers and 3-segment sampling; integrates two rail-to-rail operational amplifiers with a slew rate of 16V/μs, supporting 1 to 16 gain levels and differential input; is equipped with four programmable analog comparators, one dedicated to over-current protection and three for square wave zero-crossing detection; and features a built-in temperature sensor with ±5°C accuracy. These peripherals enable signal processing without the need for external companion chips.
In terms of communication interfaces, the G32F031 provides one SPI (rate up to 16Mbps), one I2C, one USART, and one UART (supporting LIN functionality). Timer resources include one 16-bit advanced timer (supporting 4 pairs of complementary 8-channel PWM outputs, with dead-time generation and brake input, capable of triggering the ADC multiple times per cycle), one 32-bit general-purpose timer (4 independent channels), two 16-bit basic timers, one 16-bit low-power timer, as well as two watchdog timers and one 24-bit system timer. The chip supports single-resistor sensorless FOC control, which can reduce hardware costs.
The G32F031 is available in six package types: LQFP32, QFN32/24/20, SSOP28, and SSOP24, suitable for compact PCB designs. The supporting software and hardware development ecosystem includes the Micro EVB evaluation board, universal high/low voltage motor evaluation boards, and reference solutions for high-speed hair dryers, high-speed blenders, drone ESCs, vacuum cleaners, and power tools, paired with Geehy's self-developed motor control algorithm platform.
The chip can be applied in fields such as smart home appliances (vacuum cleaners, high-speed blenders, range hoods, wireless chargers, high-speed hair dryers, air conditioner internal/external fans), consumer electronics, and industrial control (low-voltage water pumps, power tools, robot joints, ESCs).
Geehy's G32F0 platform features four major sub-product lines, with main frequencies ranging from 48MHz to 72MHz and storage capacities from 24KB to 128KB. More products will be released successively in the second and third quarters of 2026.
