Features
|
|
The
QuickBar is a single chip, high-speed bar code decoder. The chip is
far smaller than traditional decoding chip sets. With a minimum of
additional components, you can build a high speed and feature rich
bar code decoding subsystem. This high-speed chip has a minimum instruction
time of 0.125 µsecond when operating with an 8 MHz crystal.
Comparable 8051 type microcontollers have a 1.5 µsecond minimum
instruction time (twelve times slower). The QuickBar Chip uses "on
the fly" parallel processing to offer a very quick and robust
decode. It supports a scan speed of up to 100 scans per second. |
| Programmable
Memory |
| The
ID TECH QuickBar decode chip has a programmable memory which creates
a single chip solution with a rapid upgrade flexibility. Some vendors
use a "masked microcontroller" approach that requires at
least a SRAM chip and a latch chip, therefore a three-chip solution.
The "masked microcontroller" approach requires long lead
time for firmware revisions, ID TECH's solution provides the optimum
in performance with the added advantage of easily revising its programs.

Size |
| |
The
standard QuickBar Chip package dimensions are 17.5 mm. by 17.5 mm.
and 4.35 mm. thick (0.69" by 0.69" and .17" thick)
in a PLCC-44 package. The basic bar code decode subsystem with support
components is only about 22 mm. by 32 mm. (0.875" by 1.25")
on a two-layer board. |

| Magnetic
Stripe Decoding |
|
| The
MagBar Chip Set decodes single, dual and triple track magnetic stripes
on credit cards and driver's licenses. The chip set supports driver's
license formats accepted by the national motor vehicles standards
group AAMVA and the California Department of Motor Vehicles. The encoded
data can be in ANSI, ABA, IATA, or Thrift magnetic stripe format.
There is an option for selecting the tracks to be read, sending or
suppressing track 1 start/stop sentinels, sending the track two account
number only, and an option for selecting the track separator character
for multi-track readers. |
| Options: |
Beeper
- A good read beeper function may be added with the addition of the
beeper, a diode, a transistor and a resistor
LED - A 3mm. good read LED function may be added
without other additional components
Package Options - The QuickBar Chip is also available
in a 40 pin DIP and 44 pin TQFP package |
