Overview

The GD32H77R series high-performance 32-bit microcontrollers are dedicated MCUs deeply customized and optimized for servo drive and robot joint control applications. Equipped with an Arm^® Cortex^®‑M7 core running at up to 600 MHz, the chip features 640 KB tightly coupled memory (TCM) operating at the same frequency as the CPU. It integrates an EtherCAT® slave controller and multi-type industrial encoder interfaces, and comes in a compact 9×9 mm BGA169 package to perfectly fit the limited space inside robot joints.

The GD32H77R MCU integrates on-chip EtherCAT^® slave controller, dual 100 Mbps Ethernet PHYs and various industrial encoder interfaces. It natively supports mainstream absolute encoder protocols including EnDat, BiSS-C and Tamagawa. The built-in RDCM resolver-to-digital conversion module enables precise acquisition of motor position and speed feedback. This eliminates many external signal conditioning components and greatly simplifies hardware circuit design.

GD32H77R series MCUs are widely used in humanoid robot joint modules, servo drives, VFD variable frequency drives, 3D printers, CNC equipment, industrial gateways and multi-sensor fusion systems.
