Overview
GD32F505 series MCUs operate at a maximum frequency of 280 MHz, leveraging the efficient Arm® v8-M architecture with built-in advanced DSP hardware accelerators and a single-precision floating-point unit (FPU). They integrate three ADCs with sampling rates of up to 3 Msps (supporting up to 25 channels), along with one fast comparator and one DAC, enabling features such as rapid protection. Additionally, the series supports up to three SPIs, two I2Ss, two I2Cs, three USARTs, two UARTs, two CAN-FDs, and one USBFS interface, facilitating seamless connectivity with various external devices.
The GD32F505 series MCUs are available in multiple package options, including LQFP100/64/48, QFN64/48, and BGA64.
