Overview

The GD32FFPR series fingerprint MCUs are built around a high-performance Arm^® Cortex^®-M4 core running at up to 168 MHz, delivering up to 210 DMIPS and a CoreMark^® score of 565. This computing capability enables advanced fingerprint recognition tasks, including image preprocessing, segmentation and stitching, feature extraction, matching, cross-comparison, identification and unlocking,and more. This significantly improves both enrollment and matching efficiency.

The device integrates up to 1 MB of embedded Flash and up to 128 KB of SRAM, providing sufficient memory resources for multi-fingerprint storage and dynamic data processing during the recognition workflow. A rich set of peripheral interfaces is also integrated to enhance system connectivity and integration capability.

For security, fingerprint data is protected through hardware-level encryption and secure storage mechanisms. In addition, a built-in 96-bit unique ID (UID) helps prevent device cloning and unauthorized duplication, providing enhanced protection for biometric data integrity.

The series operates from a 2.6 V to 3.6 V supply voltage, with I/O ports supporting 5 V tolerance. It also features three low-power modes and supports automatic finger detection with interrupt wake-up for improved power efficiency.
