DESCRIPTION
FCD4A14 is part of the FingerChip
TCS monolithic
fingerprint sensor family for which no optics, no prism and no
light source are required.
FCD4A14 is a single chip, high performance, low cost sensor
based on temperature physical effects for fingerprint sensing.
FCD4A14 has a linear shape, allowing for the capture of a
fingerprint image by sweeping the finger across the sensing
area. After capturing several images, TCS proprietary
software can reconstruct a full 8-bit fingerprint image, if
needed.
FCD4A14 has a small surface combined with CMOS
technology, and a ceramic dual-in-line or Chip-On-Board
package assembly. These facts contribute to a low cost
device.
FCD4A14 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
microprocessors. Thus, no frame grabber or glue interface is
necessary to send the frames. These facts make FCD4A14
an easy device to include in any system for identification or
verification applications.
