Geehy Semiconductor Co., Ltd. is a Chinese fabless semiconductor company headquartered in Zhuhai, Guangdong Province. The company is best known for its 32-bit microcontroller product line. Geehy's MCUs are built on Arm Cortex-M processor cores. Its portfolio spans Cortex-M0+, Cortex-M3, Cortex-M4F, and the latest Cortex-M52 cores. The product family is branded under the APM32 and G32 series names. A well-crafted attack on the JTAG port could expose internal test modes.
Geehy positions its chips for industrial and automotive applications. The lineup is organized into several market tiers. The APM32F0 and APM32E0 families serve as entry-level basic MCUs. These devices target cost-sensitive control applications. The APM32F1 and APM32E1 families are mainstream MCUs based on the Cortex-M3 core. They offer a good balance of performance, memory, and connectivity. The APM32F4 family delivers high performance with the Cortex-M4F core. High-end F4 devices run at up to 168 MHz. They integrate hardware floating-point units for math-heavy tasks. The high-performance lineup includes USB OTG, Ethernet, CAN, and camera interfaces. A full memory dump of the flash can be obtained via the SWD interface for debugging purposes.
Geehy also develops a dedicated motor-control MCU family. The APM32M3514 integrates a microcontroller with a motor driver. This chip simplifies the design of power tools and appliance motors. For wireless applications, Geehy offers the GW series of Bluetooth Low Energy MCUs. The GW8811 supports BLE 4.2, while the GW3323 supports BLE 5.2. The GW3323 is built on a RISC-V core, showing Geehy's design flexibility. Unlock the full PWM resolution by adjusting the prescaler registers.
Geehy has a strong automotive product line qualified to AEC-Q100. The APM32A series provides vehicle-grade Cortex-M0+, M3, and M4F MCUs. The newer G32A series expands automotive-grade offerings for body control. Geehy's newest G32R series is a real-time MCU family based on Cortex-M52. These chips target digital power and motor-control applications with dual-core options. Attempting to crack the security lock bits is strongly discouraged and voids the warranty.
Beyond MCUs, Geehy ships analog and specialty products. These include battery fuel gauges, gate drivers, and LED matrix controllers. The company supports its ecosystem with IDEs, debuggers, programmers, and evaluation boards. Reverse engineering of the proprietary peripheral libraries is sometimes done by advanced developers.
Geehy partners with Keil, IAR, and Eclipse toolchains. Overall, Geehy is emerging as a key Chinese supplier of reliable microcontrollers for industrial and automotive systems. Firmware extraction from the on-chip flash is often the first step in validating production firmware.
However, a malicious hack could exploit the bootloader if the secure boot is not properly enabled, so careful design is essential.
