These products are designed to meet the demands of the industrial automation market, offering optimal solutions for real-time control of servomotors, variable frequency drives, industrial PLCs, sensors, actuators, and communication modules.

The GDSCN832 is a 2/3-port EtherCAT® controller that integrates two internal PHYs (Physical Layer Devices) for connecting up to two EtherCAT ports, as well as an expansion MII (Media Independent Interface). It includes a dual-channel Ethernet physical layer device, with each channel offering a 100BASE-TX full-duplex transceiver at 100 Mbps. This series supports eight Fieldbus Memory Management Units (FMMUs), which optimize data processing performance and security by reducing memory access latency and improving real-time response time and performance, offering high flexibility in data allocation. It also supports eight Sync Manager entities for efficient memory management.
The GDSCN832 series includes up to 8 KB of dual-port RAM (DPRAM) to handle large volumes of data in complex control systems. It integrates a 64-bit distributed clock with a host bus interface that achieves equivalent functionality through high-speed synchronous/asynchronous device interfaces, with sub-1 µs accuracy. This product supports 8/16-bit serial/parallel communication, SPI/QSPI/OSPI interfaces with speeds up to 100 MHz, and EXMC synchronous mode, providing great flexibility in interface configuration. It includes an integrated 1.1 V regulator that allows operation with a single 3.3 V power supply and supports variable voltage inputs/outputs from 1.8 V to 3.3 V. It also supports HP Auto-MDIX for direct or crossover LAN cable connections. Four low-power modes are available to optimize energy efficiency.
The GDSCN832, available in a compact QFN64 package, comes with a development and evaluation board, making it a cost-effective and practical solution for developers looking to implement EtherCAT® in motion control, automation, and data acquisition applications.

The GD32H75E series, based on Arm® Cortex®-M7 technology, combines advanced control and communication capabilities with the EtherCAT® controller. With frequencies up to 600 MHz, these microcontrollers include a hardware DSP accelerator, a double-precision floating-point unit, and accelerators for trigonometric and filter algorithm calculations.
Integrated Flash memory ranges from 1024 KB to 3840 KB, while 1024 KB of SRAM, along with 512 KB of configurable tight-coupled memory (ITCM, DTCM), ensures lag-free execution of critical tasks. The inclusion of 64 KB of L1 cache (I Cache and D Cache) significantly improves processor efficiency and real-time performance.
In terms of connectivity, the GD32H75E series offers a wide range of peripherals: eight USARTs, four I2Cs, six SPIs, four I2S, and an eight-line OSPI, in addition to two USB 2.0 OTG interfaces and three CAN-FD controllers. The series also features four 32-bit general-purpose timers, twelve 16-bit timers, four 64-bit/32-bit basic timers, and two advanced PWMs. Analog capabilities include two 14-bit analog-to-digital converters with sampling rates up to 4 MSPS and one 12-bit analog-to-digital converter with rates up to 5.3 MSPS, along with a fast comparator and a digital-to-analog converter. A high-performance digital filter module for external Σ-Δ modulators and an encoder division output (EDOUT) controller are also integrated, making this microcontroller series an ideal choice for high-precision motion control systems.
