Cache, up to 2KB I-Cache and 512B D-Cache, to further enhance the kernel processing performance.

Rich Peripherals for Development Innovation

GD32G5 series MCUs integrate a series of rich peripheral resources. The GD32G5 series MCUs integrate a series of rich peripheral resources, including four 12-bit ADCs with sampling rates up to 5.3MSPS and up to 42 channels, four 12-bit DACs, two of which with sampling rates up to 15MSPS, and a series of high-precision analog peripherals, such as eight fast comparators (COMP), to support a variety of motor power control scenarios. The GD32G5 series MCUs are equipped with a 16-channel high-precision timer (HRTimer) with an accuracy of up to 145 ps, as well as three 8-channel advanced timers, two 32-bit general-purpose timers, five 16-bit general-purpose timers, two 16-bit basic timers, and a low-power timer.

The GD32G5 series microcontrollers provide 5 U(S)ART, 4 I2C, 3 SPI and 1 QSPI, support up to 200MHz DDR/SDR interface; equipped with 3 CAN-FD modules for high-speed communication application scenarios; and also integrates 1 HPDF high-performance digital filter, supporting 8 Channels/4 The GD32G5 series supports a wide temperature range of -40~105°C, which can meet the differentiated scenarios of optical modules, industrial power supply, high-speed motor control, etc. with high temperature requirements.

Safe and Reliable Construction of Quality Fortress

The GD32G5 series MCUs have built-in security features that provide multiple security protection mechanisms for the communication process, including support for secure OTA, secure startup, secure debugging, secure upgrading, etc. The GD32G5 series MCUs provide 2KB of OTP memory. A 2KB OTP memory is provided to ensure that code data is not altered, thereby protecting the security and integrity of the device. This series of MCU Flash/SRAM supports ECC checksum in all areas. Built-in hardware encryption and decryption modules support DES, Triple DES or AES algorithms to ensure data security during communication. In addition, the products also support True Random Number Generator (TRNG).

The GD32G5 product family supports the system-level IEC 61508 SIL2 functional safety standard, and provides a complete Safety Package, including a series of functional safety information such as Safety Manual, FMEDA and self-test library. This helps users to accurately identify potential safety hazards and provides a solid guarantee for the stability and reliability of industrial applications.
