1. Absolute maximum ratings are limiting values, to be applied individually, while other parameters are within specified operat-
FCD4B14
ing conditions. Long exposure to maximum ratings may affect device reliability.
FCD4B14 is part of the FingerChip Atmel monolithic fingerprint sensor family for which
no optics, no prism and no light source are required.
FCD4B14 is a single chip, high performance, low cost sensor based on temperature
physical effects for fingerprint sensing.
FCD4B14 has a linear shape, allowing for the capture of a fingerprint image by sweep-
ing the finger across the sensing area. After capturing several images, Atmel proprietary
software can reconstruct a full 8-bit fingerprint image, if needed.
FCD4B14 has a small surface combined with CMOS technology, and a Chip-On-Board
or ceramic dual-in-line package assembly. These facts contribute to a low-cost device.
FCD4B14 delivers a programmable number of images per second, while an integrated
Analog to Digital Converter delivers a digital signal adapted to interfaces such as an
EPP parallel port, USB microcontroller or directly to micro-processors. Thus, no frame
grabber or glue interface is necessary to send the frames. These facts make FCD4B14
an easy device to include in any system for identification or verification applications.
