Overview

The GD32F3x0 series is designed for applications with constrained design budgets while still harnessing the exceptional performance of the Cortex^®-M4 high-performance core. It provides customers with the opportunity to replace or enhance the legacy 8-bit and 16-bit product solutions, enabling a direct upgrade to the high-speed mainstream 32-bit Cortex^®-M4 architecture.

The GD32F3x0 product series features higher operating frequencies, an expanded set of peripherals, enhanced functions, and reduced costs. It provides a cost-effective solution for cost-sensitive applications, such as industrial motors, variable-frequency drives, and energy-saving applications.
To help customers fully utilize the product's advantages, the GD32F3x0 series is compatible with the full range of hardware and software of the GD32F1x0 series and GD32E230 series.
