Overview

CXA3271GE Fingerprint Sensor Description The CXA3271GE is an electrostatic capacitance method fingerprint sensor.
This monolithic IC integrates the sensor block, sense amplifier (3-bit gain adjustment), sample-and-hold, output amplifier and output buffer needed to acquire fingerprint images, as well as the timing generator for determining the operation of these functions onto a single chip.
30 pin LLGA Features • Electrostatic capacitance type sensor (charge transfer method) • Number of pixels: 192 × 128 • 317 DPI • Low power consumption (50mW or less) • Single 3.
3V power supply • Sensor gain control: 3 bits • S/N ratio improved by on-chip sensor block parasitic capacitance cancel function ...
