Overview

The GD32FFPR series fingerprint MCUs are equipped with a 168MHz high-performance ARM^® Cortex^®-M4^® core, achieving 210DMIPS at the highest clock speed and a CoreMark^® score of 565. This enables support for advanced fingerprint recognition operations, including fingerprint image preprocessing, segmentation and splicing, data feature extraction, feature matching, cross-comparison, identification and unlocking, and more. These features significantly improve the efficiency of fingerprint registration and matching. The chip is also equipped with a large built-in Flash of 1MB and SRAM of up to 128KB, accommodating the resource needs of the identification process such as multi-fingerprint information storage and dynamic memory allocation.This series MCUs also integrate a wealth of peripheral interfaces to improve connectivity and integration. The automatic encryption and storage of fingerprint information at the bottom layer is secure and reliable. Combined with the built-in 96-bit unique ID (Unique ID), it effectively prevents the chip from being copied or stolen, providing double protection for the security of fingerprint information. The chip uses 2.6V-3.6V power supply, and the I/O port can withstand 5V level. It includes three power-saving modes and supports automatic finger detection and interrupt wake-up.
