SFC360/361 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 SFC360/361 can catch more fingerprint characteristics. The operation of SFC360/361 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.
