Fingerprint Sensor

CXA3621GE

Description

The CXA3621GE 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 (Plastic)

Features

• Electrostatic capacitance type sensor (charge transfer method)

• Number of pixels: 192 × 128

• 317 DPI

• Low power consumption (50mW or less) ∗ When P/S: 18µW or less

• Single 3.0V power supply

• Sensor gain control: 3 bits

• S/N ratio improved by on-chip sensor block parasitic capacitance cancel function
