Universal Core Hardware Features – Building a Unified High-Performance Foundation for Industrial Applications

All MCUs in the GD32H7 family are powered by the high-performance Arm® Cortex®-M7 core, offering dual frequency options of 600 MHz(GD32H77x series) and 750 MHz(GD32H78x series) with a maximum CoreMark® score of 3,736, delivering outstanding computing power and operational efficiency. Equipped with 640 KB CPU-synchronous Tightly Coupled Memory (TCM), the devices support zero-wait instruction and data execution, significantly enhancing operational stability and response speed for complex algorithms, high-frequency tasks and real-time control workloads.

The entire portfolio adopts unified storage specifications, including 2 MB high-speed executable Flash, 8 MB large-capacity storage Flash and 1.2 MB high-speed SRAM. Dual OSPI high-speed interfaces support a 200 MHz clock frequency and double data rate (DTR) mode, enabling flexible expansion of external memory devices to meet the demands of high-definition graphic caching, high-speed data logging and complex program execution. Integrated with a dedicated hardware math acceleration engine that supports trigonometric calculation, FFT and FIR filtering, the series greatly improves processing efficiency for motor control, signal analysis and algorithm computation.

Universal security and functional safety capabilities are implemented across the full product lineup. The GD32H7 family has obtained IEC 61508 SC3 (SIL 2/SIL 3) functional safety certification from TÜV Rheinland, supported MIPI by a complete functional safety development suite including safety manuals, FMEDA reports and dedicated self-test libraries. Integrated hardware security modules feature AES encryption, SHA-256 hash verification, a True Random Number Generator (TRNG) and unique chip UID. Supporting secure boot, authenticated firmware upgrade and anti-rollback mechanisms, the series is designed to help customers address the cybersecurity requirements of the EU Cyber Resilience Act (CRA) and mainstream industrial safety compliance standards.

The GD32H7 series integrates extensive industrial-grade peripherals, including multiple U(S)ART, I²C, SPI and I²S interfaces, two 10/100 Mbps Ethernet ports and 3 CAN-FD high-speed buses. Complemented by multi-channel high-precision ADC/DAC, comparators and high-speed digital filters, as well as USB HS/FS and SDIO interfaces, the portfolio fully supports high-speed industrial communication, precise analog acquisition and complex system interconnection. Covering a wide operating voltage range of 1.71 V to 3.6 V and offering multiple configurable low-power modes, the devices balance high-performance operation and power efficiency for diverse industrial operating conditions.

Differentiated Product Positioning for Targeted Industrial Scenarios

GD32H7xR Series (GD32H77R) – Dedicated MCU for Robotic Joint Servo Control

Custom-designed for collaborative robots, humanoid robots and high-precision servo equipment, the GD32H7xR series is optimized for space-constrained, high-reliability and high real-time joint control applications, serving as the core controller for robotic joint modules, miniature servo drives and high-precision CNC devices.

Featuring extreme integration and miniaturization, the single-die MCU integrates an EtherCAT® slave controller and two 100 Mbps Ethernet PHYs, eliminating the need for external PHY components. It achieves a transmission latency below 50 ns and supports the FSoE safety protocol, ensuring high-speed real-time communication and reliable equipment operation. Compatible with mainstream industrial position feedback protocols, the series delivers precise closed-loop control of motor position and speed. Packaged in a compact 9mm×9mm BGA169 form factor, the chip drastically reduces PCB footprint for joint drive boards, perfectly adapting to the limited installation space of robot joints. Optimized for dynamic power consumption and thermal performance, it ensures stable long-term operation in high-temperature and harsh industrial environments.
