216MHz GigaDevice GD32G5 Cortex-M33 MCU features analog interfaces and accelerators for industrial applications

Starting with the GD32G553 SKUs, the 216 MHz GigaDevice GD32G5 high-performance Arm Cortex-M33 microcontroller family features 256KB to 512KB of embedded Flash with dual-bank Flash support, 128KB of SRAM, and a range of hardware accelerators including a DSP, single-precision FPU, a trigonometric function accelerator (TMU), and other hardware acceleration units, filter algorithms (FAC) and Fast Fourier Transform (FFT).

Designed for industrial applications, the GD32G5 microcontrollers also offer a wide range of digital and analog interfaces and enhanced security capabilities suitable for digital power systems, charging stations, energy storage inverters, frequency converters, servo motors, and optical communication.

It’s far from the first Cortex-M33 high-performance microcontroller from GigaDevice and we previously wrote about the GD32E5 and GD32F5 family for respectively motor/industrial control and industrial applications with high-memory requirements, as well as the GD32W515 Cortex-M33 wireless SoC.

While searching for differentiating features for the GD32G5, I noticed others are clocked at up to 180/200 MHz, but the new family clocks up to 216 MHz, and it also comes with a greater number of analog units and channels with up to four 12-bit ADCs (42 channels max) and eight 12-bit DAC, as well as a range of accelerators.

Software development is done through the GD32 Embedded Builder IDE and tools like GD-LINK and the “GD32 All-In-One Programmer programming” tool. The company also launched development boards such as the GD32G553Q-EVAL and GD32G553R-EVAL full-feature evaluation boards, as well as the GD32G553V-START, GD32G553M-START, and GD32G553C-START entry-level learning kits. I could not find information about the development boards on the GigaDevice website, but Segger has some limited information.

GigaDevice says GD32G5 MCU samples and development boards are available now (through distributors), and mass production is scheduled for next month (December 2024). Additional information may be found on the product page and in the press release.

Whenever I see a high speed chip (200+ MHz) mention “Analog Interfaces” my first question is: how fast are they?
Throw in: DSP, filter algorithms, and FFT and now the data capture / processing rate becomes a significant point of interest. If those filters include a DDC / DUC (Digital Down / Up Converter) you could have an RF signal analyser, or generator.

Assuming the analog section can run at 216 MHz, of course.
