Industrial MCU packs EtherCAT controller
GigaDevice has introduced the GD32H75E 32-bit MCU, featuring an integrated GDSCN832 EtherCAT subdevice controller, which is also available as a standalone device. Both components target industrial automation applications, including servo control, variable frequency drives, industrial PLCs, and communication modules.
Powered by an Arm Cortex-M7 core running at up to 600 MHz, the GD32H75E microcontroller includes a DSP hardware accelerator, double-precision floating-point unit, hardware trigonometric accelerator, and filter algorithm accelerator. It also comes with 1024 KB of SRAM, up to 3840 KB of flash memory with security protection, and a 64-KB cache to enhance CPU efficiency and real-time performance.
The MCU’s integrated EtherCAT subdevice controller, licensed from Beckhoff Automation, manages EtherCAT communication, acting as an interface between the EtherCAT fieldbus and the sub-application. It includes two internal PHY ports and an external MII. With 64-bit distributed clock support, it enables synchronization with other EtherCAT devices, achieving DC synchronization accuracy to within 1 µs.
The GD32H75E MCU is available in two variants: one with two internal Ethernet PHYs and another that supports bypass mode, both housed in BGA240 packages. Samples and development boards are available now, with mass production planned for Q2 2025.
