The MFC-2160 fingerprint sensor is based on capacitive-touch technology with a hardened surface and enhanced ESD strength. The built-in analog and digital circuits could minimise the number of external components and provide easy-to-use standard SPI interface to microprocessors.
MFC-2160 capacitive fingerprint sensor
The operation of the MFC-2160 capacitive fingerprint sensor is as following: a fingerprint image captured by the pixel array, delivering 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 MFC-2160 capacitive fingerprint sensor can be adjusted by setting gain, offset and reference voltage parameters internally. In addition, the internal operations and interface speed can also be configured to meet various finger conditions. MFC-2160 capacitive fingerprint sensor also has a finger detection function and windowing function for different applications.
