Description
Hewlett-Packard’s Bar Code
Decoder ICs offer flexible bar
code decoding capability that is
designed to give OEMs the ability
to address a growing number of
industry segments and applica-
tions. Flexibility is made possible
through sophisticated firmware
which allows the ICs to accept
data from a wide variety of
scanners and to automatically
recognize and decode the most
popular bar code symbologies.
User implementation of the
decoder ICs is easy since it
requires only a few supporting
components and provides a
standard I/O interface.
Manufacturers of data collection
terminals, point of sale terminals,
keyboards, weighing scales,
medical equipment, test instru-
mentation, material handling
equipment, and other systems
having data collection needs are
finding a growing demand for bar
code reading capability in their
products. The HBCR-2210 series
decode ICs make it easy to add
this capability without the need to

invest in the development of bar
code decoding software.
The bar code decoder ICs are
compatible with most hand held
scanners and some medium
speed machine mounted laser
heads. The HBCR-2210 series is
compatible with fixed beam non-
contact scanners, digital wands,
and slot readers. In addition, the
decoder is optimized for use with
the Symbol Technologies moving
beam laser scanners, but is also
compatible with many other
moving beam non-contact laser
scanners with a similar interface
protocol.
The HBCR-2210 series decoder
ICs are excellent decoding solu
