SFC360 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 with standard SPI interface to microprocessors. Due to its higher sensing area (256X360 pixels), the SFC360 can catch more fingerprint characteristics. The operation of SFC360 is controlled through registers, following a simple protocol. The captured image quality can be adjusted by setting gain, offset or reference voltage parameters. The internal operation and interface speed can also be configured to the needs.
