CXA3621GE

CXA3621GE Fingerprint Sensor Description The CXA3621GE is an electrostatic capacitance method fingerprint sensor. This monolithic IC integrates the sensor block, sense amplifier (3-bit gain adjustment), sample-andhold, 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 Applications Fingerprint verification units Structure Silicon gate CMOS IC Absolute Maximum Ratings (Ta = 25°C) VSS – 0.5 to +7.0 Supply voltage AVDD, DVDD Input voltage VI VSS – 0.5 to VDD + 0.5 Output voltage VO VSS – 0.5 to VDD + 0.5 Operating temperature Topr –20 to +75 Storage temperature Tstg –25 to +125 Allowable power dissipation PD 1100 Recommended Operating Conditions Supply voltage AVDD, DVDD Ambient operating temperature Ta V V V °C °C mW 2.7 to 3.6 0 to +50 V °C Sony reserves the right to change products and specifications without prior notice.
