CXA3271GE

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 Applications Fingerprint verification units Structure Silicon gate CMOS IC Absolute Maximum Ratings Supply voltage Input voltage Output voltage Operating temperature Storage temperature Allowable power dissipation VDD VI VO Topr Tstg PD VSS – 0.5 to +7.0 V VSS – 0.5 to VDD + 0.5 V VSS – 0.5 to VDD + 0.5 V –20 to +75 °C –25 to +125 °C 970 mW Operating Conditions Supply voltage Recommended operating temperature 3.15 to 3.45 0 to +50 V °C Sony reserves the right to change products and specifications without prior notice.
