Overview

GD32F5 series high-performance MCUs offer significantly expanded storage space, excellent processing efficiency, and a wide array of interface options. Compliant with the system-level IEC61508 SIL2 functional safety standard, they provide a comprehensive software and hardware security solution to meet the industrial market's demands for high reliability and security applications.

GD32F5 series high-performance MCUs adopt the Arm^® Cortex^® -M33 core with a maximum operating frequency of 280MHz. They are equipped with advanced DSP hardware accelerators and single-precision floating-point units (FPUs), which significantly reduce the burden on the core and enhance processing efficiency. GD32F5 series high-performance MCUs are equipped with up to 7.5MB on-chip Flash and 1MB SRAM. This includes a 2MB configurable zero-wait execution area (Code-Flash) that effectively improves code processing efficiency and real-time performance. They also provide a large Data-Flash space for backup and parameter storage.

GD32F5 MCU series includes various built-in security features to ensure the protection of device information. This MCU series provides multiple levels of code and data protection areas, as well as an EFUSE area, supporting various mechanisms such as secure OTA, secure boot, secure debugging, and secure downloading. For ease of use, GD32 has introduced the new Security Boot and Update software platform, offering secure booting, secure upgrading, secure communication, and software solutions. Users can conduct secondary development based on their specific requirements. The GD32F5 MCU series also supports system-level IEC61508 SIL2 functional safety standards, providing a complete Safety Package including a Safety Manual, FMEDA, and a self-test library, among other functional safety materials.

The high-performance GD32F5 MCU series integrates a wealth of general-purpose peripheral resources, including eight U(S)ARTs, six I2C interfaces, six SPI interfaces, two I2S interfaces, and one SDIO interface. It is equipped with a USB2.0 OTG interface that supports both Full Speed and High-Speed modes. Additionally, it integrates two channels of CAN-FD controllers and one Ethernet interface to meet the requirements of industrial control networking and communication applications.
