On January 22, GigaDevice officially announced the expansion of its next‑generation GD32H7 series of ultra‑high‑performance MCUs, introducing two core families: the GD32H789/779 general‑purpose MCUs and the GD32H78E/77E MCUs with integrated EtherCAT® slave controllers for extreme real‑time performance. Based on the Arm® Cortex®‑M7 core running at up to 750 MHz, the series combines a high‑speed large‑memory architecture with 640 KB of tightly coupled memory (TCM) that operates at CPU frequency, delivering a balance of high performance, low dynamic power, and fast communication. The series has won multiple industry awards, setting a new performance benchmark in the MCU space and providing a core hardware foundation for next‑generation smart equipment.
The GD32H7 series suits a wide range of applications including servo control, variable‑frequency drives, digital power supplies, portable electronics, smart home, and fire‑safety systems, with particular strength in industrial automation and embodied‑intelligent robotics, supporting Industry 4.0 advancement.
Performance Breakthrough with Compute and Efficiency
All GD32H7 MCUs feature the powerful Cortex‑M7 core at 750 MHz for strong compute output. Memory is comprehensively upgraded, supporting up to 2 MB Execution Flash and 8 MB Storage Flash, 1.2 MB SRAM, and a dedicated 640 KB TCM that runs at CPU frequency, enabling zero‑wait execution of instructions and data. This innovative architecture ensures sustained compute performance for high‑real‑time tasks, complex algorithms, and data‑intensive processing, delivering faster system response and greater stability.
Flexible Expansion and Rich Connectivity for Complex Applications
The series offers exceptional flexibility in external storage and expansion, with two OSPI interfaces supporting clock rates up to 200 MHz and double‑data‑rate (DTR) mode for efficient direct connection to PSRAM, HyperRAM, NAND Flash, and NOR Flash. It also integrates a 16/32‑bit EXMC module for direct interfacing with external SDRAM and FPGA, significantly boosting system memory capacity and data‑processing bandwidth. This enables complex system integration and customized hardware co‑processing, supports multiple protocols on a single chip, and facilitates various industrial Ethernet solutions for rapid secondary development.
GD32H78E/77E: Core Choice for High‑End Motion Control
The GD32H78E/77E series targets real‑time demands with an integrated EtherCAT® slave controller that achieves a DC sync‑cycle accuracy of 62.5 µs, meeting industry‑leading standards. It easily supports complex multi‑axis coordination and high‑dynamic response control, perfectly matching strict timing‑consistency requirements in industrial automation, robotics, and CNC machinery. The series also includes a comprehensive high‑performance encoder interface that natively supports major industrial encoder protocols such as Tamagawa T‑format, HIPERFACE DSL, EnDat 2.2, BiSS‑C, and Nikon A‑format, as well as resolvers, with communication interfaces featuring CBC protection. Combined with the powerful core, it directly interfaces with high‑end servo motors and precision position sensors, offering a highly integrated, one‑stop solution for servo drives, robot joint controllers, and CNC systems.
GD32H789/779: Universal High‑Performance Benchmark
The GD32H789/779 series, as general‑purpose high‑performance MCUs, provides a full‑featured communication and interaction hub while making a major breakthrough in analog performance. Its built‑in 14‑bit ADC delivers excellent effective‑bit performance, and the integrated high‑performance digital filter (HPDF) module can directly process external high‑precision Sigma‑Delta ADCs, forming a complete high‑accuracy solution from on‑chip to external expansion. Peripheral resources are extensive, covering advanced multimedia (graphics‑processing accelerator, TFT‑LCD interface, digital‑camera interface), high‑speed wired communication (8× U(S)ART, 4× I²C, 6× SPI, 4× I²S), advanced networking and bus interfaces (2× 10/100 Mbps Ethernet, 3× CAN‑FD), a high‑performance analog system (2× 14‑bit ADC, 1× 12‑bit ADC, 2× 12‑bit DAC, etc.), and high‑speed data interfaces (1× USB HS OTG, 1× USB FS, 2× SDIO), meeting diverse complex application needs.
Full‑Stack Security and Compliance
The GD32H7 series builds a full‑stack security framework from hardware to software, systematically implementing secure boot, secure debug, code protection, and secure update functions. Leveraging a software platform based on Secure Boot and Secure Firmware Update (SBSFU) alongside hardware mechanisms such as user‑secure‑storage areas, it provides multi‑level protection for code and data, ensuring reliability throughout firmware updates and integrity checks.
On the hardware‑encryption side, the chip includes a CAU module supporting DES, TDES, and AES algorithms with efficient DMA transfer capability; an HAU module for SHA‑1, SHA‑256, and other hash algorithms to ensure data security and authentication; EFUSE for secure storage of critical parameters; and an integrated TRNG true random‑number generator. The series’ MCU STL has achieved TÜV Rheinland IEC 61508 SC3 (SIL 2/SIL 3) functional‑safety certification, fully supporting industry safety standards such as IEC 60730 Class B, helping customers easily comply with regulations like the EU Cyber Resilience Act (CRA) and accelerating market access.
Multiple Packages and Clear Mass‑Production Plan
The GD32H78E/77E and GD32H789/779 series are offered in five package types including BGA176/100 and LQFP176/144/100, catering to diverse design needs. Currently in the early market‑introduction phase, samples and technical resources can be requested through GigaDevice’s official sales network, with mass production scheduled to begin in June 2026.
