The GD32G5 (GD32G553) product lineup is currently comprised of 14 models offered in seven different package types and with either 256KB or 512KB flash.
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.
