Overview

The GD32F505 series MCUs are based on the Arm® v8-M architecture and operate at frequencies of up to 280 MHz. Equipped with advanced DSP hardware accelerators and a single-precision floating-point unit (FPU), the series delivers efficient processing capability for compute-intensive applications.

The series integrates three ADCs with sampling rates of up to 3 Msps, supporting up to 25 channels, along with one fast comparator and one DAC to support functions such as fast protection response.

For connectivity, the GD32F505 series integrates a comprehensive set of interfaces, including up to three SPIs, two I2Ss, two I2Cs, three USARTs, two UARTs, two CAN-FDs, and one USB FS interface, facilitating seamless connectivity with various external devices.

The GD32F505 series MCUs are available in LQFP48, LQFP64, LQFP100, QFN48, QFN64, and BGA64 package options.
