The SFC160S is a powerful capacitive fingerprint sensor with SPI interface. There are 160x160 sensor pixels to construct sensor area of 8.0´8.0 mm2 because each pixel size is 50´50 µm2. It is used to detect fingerprint capacitance change with difference between the ridge and valley of user’s fingers.

Host can control or access the SFC160S easily depending on the SPI command protocol. The SFC160S can provide above 30 frames/secfingerprint data to host due to high speed scan rate of analog front end (AFE) and high speed communication of  SPI. It can offer enough fingerprint information within a short time, so as to shorten the time to identify. In addition to original fingerprint data transmitted to HOST via SPI interface, the SFC160S also provides 64-bit key data encryption for security purposes to protect the original fingerprint data.

For low power consumption issue, the SFC160S has IDLE mode to implement finger-on detection. When in finger detection mode, it can provide about 50 µA and in Power Down mode, it just consumes less 3 µA.
