Overview

The GD32F30x product series belongs to the mainstream lineup of the GD32 MCU Family. It is a 32-bit general-purpose microcontroller based on the Arm® Cortex®-M4 RISC core, delivering an excellent balance between performance and cost through enhanced processing capability, reduced power consumption, and a rich peripheral set. The Cortex®-M4 core integrates a full DSP instruction set, enabling efficient digital signal control for applications that require a seamless combination of control and signal processing. It also includes a Memory Protection Unit (MPU) and advanced trace capabilities, providing enhanced application security and improved debugging support.

The GD32F30x series features an Arm® Cortex®-M4 core operating at up to 120 MHz with zero-wait state Flash access, ensuring high execution efficiency. It offers up to 3072 KB of on-chip Flash memory and 96 KB of SRAM. A wide range of enhanced I/Os and peripherals are connected via two APB buses, enabling flexible system integration.

The device operates from a 2.6 V to 3.6 V power supply and supports an operating temperature range of –40 °C to +85 °C. Multiple power-saving modes allow flexible optimization between wake-up latency and power consumption, making it well-suited for low-power applications.

These features make the GD32F30x series suitable for a broad range of interconnected and advanced applications, including industrial control, consumer and handheld devices, communication networks, embedded modules, human-machine interfaces, alarm systems, display and graphics applications, automotive navigation, IoT and more.
