Description

The AT77C102B is part of the Atmel FingerChip monolithic fingerprint sensor family for which no optics, no prism and no light source are required.

The AT77C102B is a single-chip, high-performance, low-cost sensor based on temperature physical effects for fingerprint sensing.

The AT77C102B has a linear shape, which captures a fingerprint image by sweeping the finger across the sensing area. After capturing several images, Atmel proprietary software can reconstruct a full 8-bit fingerprint image.

The AT77C102B has a small surface combined with CMOS technology, and a Chip-on-Board package assembly. These facts contribute to a low-cost device.

The device AT77C102B delivers a programmable number of images per second, while an integrated analogto-digital converter delivers a digital signal adapted to interfaces such as an EPP parallel port, a USB microcontroller or directly to microprocessors. No frame grabber or glue interface is therefore necessary to send the frames. These facts make AT77C102B an easy device to include in any system for identification or verification applications.
