GigaDevice has launched a new-generation GD32H7 MCU1. microprocessor control unit2. mobile calibration unit3. microcontrollerA microcontroller is a compact integrated circuit designed to execute embedded control tasks in electronic systems. portfolio that is designed around a single underlying chip architecture and split into variants for three industrial scenarios: human-machine interfaces, general industrial automation and robotic servo joint control. The company positions the line as a reusable platform for industrial manufacturers that need one hardware and software foundation across multiple device classes.
At the core of the family is an Arm Cortex-M7, with clock options of 600 MHzmegahertzFrequency unit equal to one million cycles per second. for the GD32H77x series and 750 MHzmegahertzFrequency unit equal to one million cycles per second. for the GD32H78x series. GigaDevice specifies a maximum CoreMark score of 3736. The devices include 640 KB of CPUcentral processing unitMain processor that executes program instructions and performs data operations.-synchronous TCM1. tunneling current microscopyMicroscopy technique for imaging and characterizing fine material structures.2. Tightly Coupled MemoryTCM is a particularly fast-connected memory for time-critical data and instructions. to support zero-wait instruction and data access, which is intended to improve response time for complex algorithms, fast control loops and real-time workloads.
The memory configuration is shared across the portfolio and includes 2 MBmachine batch of executable Flash, 8 MBmachine batch of storage Flash and 1.2 MBmachine batch of SRAM1. static random access memoryMemory technology or system for temporarily or permanently storing digital information.2. static random-access memorySRAM is used here as a test vehicle for embedded memory performance.. Two OSPI interfaces support 200 MHzmegahertzFrequency unit equal to one million cycles per second. operation in DTR mode. GigaDevice also integrates a hardware math accelerator for trigonometric functions, FFTfast Fourier transformEfficient algorithm for computing the discrete Fourier transform of signals. and FIR filtering, targeting motor control, signal analysis and other compute-heavy tasks.
Safety and security are a central part of the platform. The GD32H7 family has IECinfused emitter coupling 61508 SC3 certification for SILSystems Integration Lab (was ATF) 2 and SILSystems Integration Lab (was ATF) 3 applications from TÜV Rheinland. The devices add AES1. Auger emission spectroscopyAnalytical measurement method that derives sample properties from a characteristic spectrum.2.

GigaDevice says this is intended to help customers address CRA-related cybersecurity requirements and industrial safety standards.
The peripheral set is broad and includes multiple U(S)ART, I²C, SPISoftware Process ImprovementSoftware-related method or tool for development, control or data processing. and I²S blocks, two 10/100 Mbps Ethernet ports, 3 CANController Area NetworkCAN is a widely used in-vehicle communication protocol.-FDfully depletedSemiconductor condition in which nearly all mobile carriers are depleted from a region. buses, multi-channel ADC/DAC resources, comparators, high-speed digital filters, USBUniversal Serial BusUSB is a standard interface for peripheral connectivity and data transfer. HS/FS and SDIO. The operating voltage range is 1.71 V to 3.6 V, and several low-power modes are available. These features are paired with the goal of supporting high-speed communication, analog acquisition and system interconnection in industrial equipment.
For robotic joint control, the GD32H7xR series integrates an EtherCAT slave controller and two 100 Mbps Ethernet PHYphysical layer interfacePHY denotes the physical-layer interface of a data link.s on a single die, removing the need for external PHYphysical layer interfacePHY denotes the physical-layer interface of a data link. components. GigaDevice states a transmission latency below 50 ns and support for FSoE. The series is packaged in a 9 mm × 9 mm BGA169 package and is intended for space-constrained joint modules, miniature servo drives and precision CNC1. computer numerical controlComputer control of machine tools using programmed movements.2. condensation nucleus counterInstrument that grows tiny aerosol particles by condensation so they can be counted. systems.
For industrial HMI applications, the GD32H7xD series adds a native 2-lane MIPI DSI display interface, an Image Processing Accelerator, and audio interfaces including 4 SAI channels, 4 I²S channels and S/PDIF. For industrial automation, the GD32H7xE and GD32H7x9 series focus on motion control and general-purpose control, with EtherCAT, encoder protocol support such as EnDat, BiSS-C, Tamagawa and HIPERFACE DSL, resolver-to-digital conversion, a 14-bit ADC1. analog-to-digital converterCircuit that converts an analog input signal into digital values.2. automated data collectionSystem or method for collecting, storing, exchanging or analyzing data.3. automatic defect classificationMeasurement or inspection concept for tracking defects and process variations in manufacturing. and an HPDF filter. Full sample availability is targeted for January 2027, with mass production scheduled for April 2027.
