GEEHY SEMI
APM32 microcontrollers and Arm Cortex-based embedded ICs
About the manufacturer
Geehy Semiconductor develops microcontrollers and integrated circuits for embedded, industrial and control applications. A central part of its portfolio is the APM32 family of 32-bit microcontrollers based on Arm Cortex-M cores, covering devices from cost-sensitive control MCUs to higher-performance parts with larger memory resources and advanced peripherals.
The APM32 range includes Cortex-M0+, Cortex-M3 and Cortex-M4F devices with combinations of Flash, SRAM, timers, ADC and DAC resources, USB, CAN and common serial interfaces. This scalability allows engineers to select a device according to processing requirements, memory size, package and peripheral mix while retaining a familiar embedded-development model across several performance classes.
Geehy microcontrollers are used in automation, IoT equipment, motor control, power electronics, industrial panels and communication products. For new designs or second-source evaluations, selection should go beyond CPU clock frequency and include pin count, peripheral mapping, analog performance, timer capability, operating voltage, temperature range and development-tool support. Firmware portability and package compatibility are especially important when the device is being evaluated as an alternative to an established MCU family.
Applications
Geehy microcontrollers can be used in both simple control devices and more advanced communication and industrial systems.
- automation and control.
- IoT and embedded devices.
- motor control and power electronics.
- USB/CAN/UART/SPI/I2C communication interfaces.
- industrial panels and equipment.
- Digital power and inverter control – timer, ADC and communication functions.
- Human-machine interfaces – control of displays, keys and communication peripherals.
