Fingerprint Sensor

Description

30 pin LLGA

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.

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
