GigaDevice GD32G5 Series MCUs Launched with Arm Cortex-M33 Core for Industrial Applications

GigaDevice has introduced the GD32G5 series high-performance microcontrollers (MCUs) based on the Arm Cortex-M33 core, designed for industrial applications like digital power systems, charging stations, energy storage inverters, servo motors, and optical communication.

These MCUs feature exceptional performance with a clock speed of up to 216 MHz, advanced DSP and FPU units, and specialized hardware accelerators such as a trigonometric function accelerator (TMU), filter algorithm (FAC), and Fast Fourier Transform (FFT) units, delivering 316 DMIPS and a CoreMark score of 694. They include extensive memory options of 256KB–512KB eFlash with dual-bank support and 128KB SRAM (includes 32KB Tightly Coupled RAM), high-speed ADCs, DACs, timers, communication interfaces, and built-in security features like secure boot, encryption modules, and ECC memory.

For communication, the MCUs offer five U(S)ARTs, four I2Cs, three SPIs, and one QSPI (up to 200 MHz DDR/SDR), along with three CAN-FD modules for high-speed data transfer. Additional features include an HPDF with external Σ-Δ modulator support, four configurable logic modules, and a flexible Trigsel module for trigger configuration.

This isn’t GigaDevice’s first high-performance MCU with a Cortex-M33 core. Previously, they introduced the GD32W515, a wireless SoC based on the same architecture. We have also covered some Arm Cortex-M33-based NXP MCUs such as the RW612,  I.MX RT700 AI crossover MCU, the MCX A series, and many more. Feel free to check those out, if you are interested in this topic.

The GD32G5 series includes 14 models available in seven package types, offering options with 256KB or 512KB flash memory.
