The GD32G5 series MCUs are powered by the high-performance Arm^® Cortex^®-M33 core, with a clock frequency of up to 216 MHz. These MCUs feature an advanced DSP hardware accelerator and a single-precision floating-point unit (FPU). They also integrate a hardware trigonometric function accelerator (TMU), along with various other hardware acceleration units, including filter algorithms (FAC) and Fast Fourier Transform (FFT), which significantly enhance processing efficiency.

The GD32G5 series MCUs are equipped with 256KB to 512KB of embedded Flash memory, supporting the dual-bank Flash feature, and 128KB of SRAM, which includes 32KB Tightly Coupled Memory RAM (TCMRAM) for zero-wait execution of critical instructions and data. Additionally, they feature high-speed cache memory, with up to 2KB I-Cache and 512B D-Cache, further boosting core processing performance.

The GD32G5 series MCUs integrate a comprehensive range of peripheral resources. They support four 12-bit ADCs with a sampling rate of up to 5.3 MSPS and up to 42 channels, as well as four 12-bit DACs, two of which offer sampling rates as high as 15 MSPS. Additionally, the series includes eight high-speed comparators (COMPs) and a suite of high-precision analog peripherals. The GD32G5 series also features a 16-channel high-precision timer (HRTimer) with accuracy reaching 145 ps, along with three advanced 8-channel timers, two 32-bit general-purpose timers, five 16-bit general-purpose timers, two 16-bit basic timers, and one low-power timer. In terms of communication interfaces, the GD32G5 series offers five U(S)ARTs, four I2Cs, three SPIs, and one QSPI supporting up to 200 MHz DDR/SDR interfaces. The MCUs are equipped with three CAN-FD modules, ideal for high-speed communication applications. Additionally, they integrate one HPDF (high-performance digital filter) supporting 8 channels and 4 filters, with external Σ-Δ modulator support. The series also includes four configurable logic modules (CLAs) and the Trigsel module, which allows flexible configuration of trigger sources. Designed to operate in a wide temperature range from -40°C to 105°C, the GD32G5 series is well-suited for demanding applications such as optical modules, industrial power supplies, and high-speed motor control, where stringent temperature requirements must be met.The GD32G5 series MCUs are equipped with multiple security features that provide robust protection mechanisms during communication, including secure OTA updates, secure boot, secure debug, and secure firmware upgrades. Supports the system-level IEC 61508 SIL2 functional safety standard, offering a comprehensive Safety Package, which includes a Safety Manual, FMEDA (Failure Modes, Effects, and Diagnostic Analysis), and a self-test library. It can be widely applied across diverse scenarios such as digital power systems, charging stations, energy storage inverters, frequency converters, servo motors, and optical communication.
