Overview

The GD32H78E/77E series high-performance 32-bit general-purpose microcontrollers are built around the Arm^® Cortex^®-M7 core with a maximum clock frequency of 750 MHz. They adopt a high-speed large-capacity memory architecture and feature 640 KB tightly coupled memory (TCM) operating at the same frequency as the CPU.

The GD32H78E/77E series integrates an EtherCAT^® slave controller with DC synchronization cycle accuracy improved up to 62.5 microseconds. It meets stringent requirements for timing consistency in industrial automation, robotics, CNC machine tools and other fields, delivering a highly integrated all-in-one solution for servo drives, robot joint controllers and CNC systems.

Advanced Networking & Buses: Integrated EtherCAT^® SubDevice Controller, 2×10/100 Mbps Ethernet, 3×CAN-FD
High-speed Wired Communication: 8×U(S)ART, 4×I2C, 6×SPI, 4×I2S
High-performance Analog Subsystem: 2×14-bit ADC, 1×12-bit ADC, 2CH×12-bit DAC, 2×COMP, 1×HPDF
High-speed Data Interfaces: 1×USB HS OTG (on-chip PHY), 1×USB FS (on-chip PHY), 2×SDIO
