In December 2013, we delivered a fingerprint sensor based on capacitive sensing method. The sensor achieved the following feature and performance goals:

• 20Mhz SPI interface with simple control protocol.

• 2 mega pixel-per-second throughput with 8bit image format.

• 1.2mA low power consumption in operation mode.

• 15uA low power consumption in stand-by mode with finger detection.

• Symmetric image data encryption with 64-bit key stored in OTP memory.
