AT77C105A - FingerChip Thermal Fingerprint Sweep Sensor

Description

Atmel’s AT77C105A fingerprint sensor is dedicated to PDA, cellular and smartphone applications.

Based on FingerChip thermal technology, the AT77C105A is a linear sensor that captures fingerprint images by sweeping the finger over the sensing area.

Features

  • Thermal Sensitive Layer Over a 0.35 µm CMOS Array Image Zone: 0.4 x 11.6 mm Image Array: 8 × 232 = 1856 Pixels Pixel Pitch: 50 × 50 µm = 500 dpi Resolution On-chip 8-bit Analog to Digital Converter Serial Peripheral Interface (SPI) - 2 Modes:.
  • Fast Mode at 16 Mbps Max for Imaging.
  • Slow Mode at 200 kbps Max for Navigation and Contr.
