Zhuhai, ChinaMay 14, 2026 /PRNewswire/ — The motor drive industry is moving toward high energy efficiency and extreme cost optimization. Responding to market demands, Geehy has officially launched the first motor control MCU of its new-generation G32F0 platform—the G32F031—bringing a more efficient, versatile, and cost-effective domestic motor main control chip solution to the motor industry.
Geehy G32F0 Platform
Redefining Motor Control Dedicated MCUs
From the outset, the G32F0 platform was designed based on practical customer application needs, with breakthroughs and upgrades at the underlying architecture level. This series comprehensively enhances system capabilities, computing performance, and peripheral configurations. It is equipped with an Arm® Cortex®-M0+ core, built-in multiple algorithm acceleration units, and Flash access acceleration, providing ample computing power for FOC vector control. It efficiently helps customers simplify hardware design, achieving comprehensive cost reduction and efficiency improvement.
Native Algorithm Support
Enabling Precise FOC Control
As the debut product of the G32F0 motor control dedicated MCU platform, the G32F031 integrates all-in-one main control capabilities with high adaptability. It operates at a main frequency of 64MHz, supports a wide voltage supply range of 1.8V~5.5V, and integrates 64KB Flash and 8KB SRAM. With built-in DIV/MULT/CRC algorithm acceleration units, it achieves low-latency, high-efficiency sensor-based/sensorless FOC vector control, delivering a qualitative improvement in computing efficiency over ordinary MCUs.
G32F031 Series Product Features Overview
Precise Sensing & Efficient Connectivity
Enabling High-Efficiency Signal Processing and Communication
The analog peripherals of the G32F031 form a one-stop signal processing system, capable of handling high-bandwidth, high-slew-rate signals without the need for external chips, comprehensively enhancing the system’s ability to sense and monitor motor operating status.
- High-Precision ADC: Built-in 1 12-bit ADC (maximum sampling rate 2MSPS), supporting 8 independent result registers and 3-segment segmented sampling. Channel sampling time can be individually configured, enabling fast capture of analog signals.
- Robust Operational Amplifier PGA: Integrated 2 rail-to-rail operational amplifiers (Op-Amp) with a slew rate of up to 16V/μs (ample margin for single-resistor and high-current applications). Supports 1~16 multi-level internal/external gain and differential input, and provides four internal bias options: VDDA/2, VDDA/4, BG, and BG/4.
- Functionally Distinct Comparators: Equipped with 4 programmable analog comparators (COMP). 1 is dedicated to overcurrent protection, supporting digital filtering and internal cascading. 3 are dedicated to square wave zero-crossing detection, with a built-in center point network and configurable hysteresis on both edges.
- Temperature Sensor: Accuracy ±5°C, eliminating the need for external thermistors. Precise temperature monitoring is achieved through direct reading via the internal ADC.
The G32F031 also features a rich set of communication interfaces, including 1 SPI (communication rate up to 16Mbps), 1 I2C, 1 USART, and 1 UART (with LIN function support), catering to diverse communication and expansion needs, effectively ensuring efficient and reliable data transmission between devices.
Flexible Control
Building an Advanced Timer Network
The G32F031 integrates abundant timer resources, supporting single-resistor sensorless FOC control, significantly reducing hardware costs and further enhancing motor control flexibility.
- 1 16-bit Advanced Timer: Supports 4 pairs of complementary 8-channel PWM output, with dead-time generation and brake input functions. It can trigger the ADC multiple times in a single cycle, meeting the high-precision speed regulation needs of BLDC and stepper motors.
- 1 32-bit General-Purpose Timer: 4 independent channels, eliminating weak links in the signal chain for more precise pulse capture.
- 2 16-bit Basic Timers: Flexibly handle PWM output and basic PWM capture.
- 1 16-bit Low-Power Timer: Achieves precise low-power wake-up or timeout management.
- 2 Watchdog Timers and 1 24-bit System Timer: Multi-layered safety assurance, preventing motor runaway caused by program crashes.
Minimalist Design
Small Package, Big Power
The G32F031 is available in six package types: LQFP32, QFN32/24/20, SSOP28, and SSOP24. This significantly reduces the number of external components, optimizes PCB area, and perfectly suits compact PCB designs, helping customers achieve more innovative functions at lower costs.
