Square Capacitive Fingerprint Sensor for Door Lock

Overview

The MFC****2 fingerprint sensor is based on capacitive-touch technology with a hardened surface and enhanced ESD strength. The built-in analog and digital circuitries minimize the number of external components and provide easy-to-use, standard SPI interface to microprocessors.

The operation of the MFC****2 fingerprint sensor is as following, a fingerprint image captured by pixel array, delivery fingerprint ridge or valley signals to A/D converter and digital processor, then to the serial peripheral interface for data-reading. The image quality of the MFC****2 fingerprint sensor can be adjusted by setting gain, offset and reference voltage parameters internally. In addition, the internal operation parameters and interface speed can also be configured to meet various finger conditions.

MFC****2 capacitive fingerprint sensor also has a finger detection function and windowing function for different applications such as door lock or access control. This sensor is **0% made in Taiwan. We also provide the custom ROM service.
