High Speed Decoding Chip for Bar Codes
Für diese Artikel bestätigen wir hiermit RoHS-Konformität
|
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 |

| 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 available
in a 44-pin TQFP or PLCC package. The QuickBar II, which supports additional
symbologies in a single chip, is available in a 44-pin TQFP package
only.

| 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. |
