1 Overview
1.1 Description
The SF104x fingerprint image sensor module is based on capacitive-contact
technology with hardened surface and enhanced ESD resistivity. The build-in analog and
digital circuitry minimizes the number of external component, and provides easy-to-use,
standard SPI interface to microprocessors.
The operation of SF104x is controlled through fingerprint image sensing by pixel array,
A/D converting, digital process, following is simple interface protocol. The captured image
quality of SF104x can be adjusted by setting gain, offset and reference voltage parameters.
In addition, the internal operation parameter and interface speed can also be configured to
the need.
