GigaDevice announces GD32F5 Cortex-M33 microcontroller targeted at high-performance applications

GigaDevice has officially launched the GD32F5 microcontroller series based on the Arm Cortex-M33 core. The Arm Cortex-M33 core has a maximum operating frequency of 200MHz and a working performance of up to 3.31 CoreMark/MHz. It also comes with a digital signal processing extension and a single-precision floating-point unit to reduce the load on the core.

The GD32F5 microcontrollers are designed for high-performance applications and come equipped with up to 7.5MB on-chip flash, 1MB static RAM (SRAM), and diverse connectivity peripherals. The on-chip flash includes a zero-wait execution area (code flash) to improve code processing efficiency and real-time performance, and sizable data flash space for storing backups and parameters. The products support seamless OTA updates with a maximum of 2MB for Read-While-Write (RWW) operations.

According to GigaDevice, the GD32F5 series is expected to find applications in “energy and power management, photovoltaic energy storage, industrial automation, programmable logic controllers (PLC), network communication devices, and graphic displays”.

GigaDevice offers various development tools for the GD32F5 microcontroller series, including a free GD32 IDE, GD-LINK debugging and download tool, and the GD32 All-In-One Programmer. GigaDevice has also partnered with SEGGER to offer their emWin embedded graphics library to all users of GD32 series Arm Cortex-M microcontrollers, including the new GD32F5 series.

GigaDevice GD32F5 MCUs series

The GD32F5 series comes in five packages: BGA176, LQFP176/144/100/64, with 10 product models in total. Complementary development boards have also been launched for evaluation, debugging, and entry-level learning. They will be released to authorized distribution channels at an undisclosed date. Customers are encouraged to contact their local GigaDevice sales office or authorized representative for more details.

GigaDevice says GD32F5 samples are currently available, and mass production will begin in May 2024. More information may be found on the product page and in the press release.
