The GD32F5 series high-performance MCUs offer significantly expanded storage capacity, excellent processing efficiency, and a wide range of interface options. They comply with the IEC61508 SIL2 functional safety standard at the system level, providing a comprehensive software and hardware security solution to meet the demands of the industrial market for high-reliability and high-security applications.
The GD32F5 series high-performance MCUs utilize the Arm® Cortex®-M33 core with a maximum operating frequency of 200 MHz and a performance of up to 3.31 CoreMark®/MHz. They are equipped with advanced DSP hardware accelerators and single-precision floating-point units (FPUs), which significantly reduce the load on the core and improve processing efficiency.
The GD32F5 series is equipped with up to 7.5 MB of on-chip Flash memory and 1 MB of SRAM. This includes a configurable 2MB zero-wait execution area (Code-Flash) that effectively improves code processing efficiency and real-time performance. It also provides ample Data-Flash space for backup and parameter storage. SRAM/Flash is fully ECC-compliant to ensure stable and reliable storage, effectively adapting to various complex industrial application environments. The GD32F5 series supports up to 2MB for read-while-write (RWW) over-the-air (OTA) updates to ensure smooth code updates without operational interruption, thus guaranteeing real-time performance and stability.
The External Memory Controller (EXMC) supports access to a variety of external memory devices such as SDRAM, SRAM, ROM, NOR Flash, NAND Flash, and PC cards. With its large storage capacity, the GD32F5 meets the needs of complex industrial systems for code updates and backups.
The GD32F5 MCU series includes several built-in security features to ensure the protection of device information. This MCU series provides multiple levels of data and code protection areas, as well as an EFUSE area, which supports various mechanisms such as secure OTA, secure boot, secure debugging, and secure download. To facilitate its use, GD32 has introduced the new Security Boot and Update software platform, which offers secure boot, secure update, secure communication, and software solutions. Users can perform secondary development according to their specific requirements. The GD32F5 MCU series also supports IEC61508 SIL2 functional safety standards at the system level, providing a comprehensive safety package that includes a safety manual, FMEDA, and a self-test library, among other functional safety materials.
The high-performance GD32F5 MCU series integrates a large number 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 USB 2.0 OTG interface that supports full-speed and high-speed modes. Additionally, it integrates two CAN-FD driver channels and an Ethernet interface to meet the requirements of industrial control networking and communication applications.
The high-performance GD32F5 MCU series operates on a 1.71V to 3.6V power supply and features two 32-bit general-purpose timers, eight 16-bit general-purpose timers, two 16-bit basic timers, and two advanced PWM timers. It also supports three 12-bit ADCs, two DACs, and other high-precision analog peripherals to meet the requirements of motor frequency conversion, industrial control, and other application scenarios.
GD32F5 product family and
the GD32 development ecosystem are continuously expanding and improving. GigaDevice provides the new high-performance GD32F5 series with the free GD32 IDE (Embedded Builder) development environment, the GD-LINK debugging and downloading tool, and the GD32 All-In-One Programmer.
