HBCR-1611 Agilent(Hewlett-Packard), HBCR-1611 Datasheet - Page 2

• Manufacturer Part Number: HBCR-1611
• Description: Single Chip Bar Code Decode IC
• Manufacturer: Agilent(Hewlett-Packard)

Power Requirements
The decoder IC is operated from
a +5 volt DC power supply. The
maximum current draw is 24 mA.
The maximum power supply
ripple voltage should be less than
100 mV, peak-to-peak.
Idle Mode
The IC automatically reduces
power consumption whenever
there is no scanning or decoding
activity, or when there is no
activity on the I/O port. See
Table 4.
Manual
The HBCR-1610 Series Users
Manual (HBCR-1697) covers the
following topics:
• Specifications and Timing
• Pin Definitions and Schematics
• General Scanning Tips
• Configuration and Operation
• Escape Sequence Programming
• Data Output Formats
• Sample Bar Codes
• I/O and Pacing Characteristics
IC Configuration
The default configuration is set
when the IC powers up or when a
Hard Reset command is received.
Default configuration of many of
the options is dependent on the
logic states of IC pins, as shown
in Table 5. A complete descrip-
tion of the pins and all possible
configurations is in the Users
Manual. More complete and
flexible configuration is achieved
using escape sequence
commands.
There are two pins that cause
significant changes in the IC
operation.

FRQ Pin
The FRQ pin is used to tell the IC
what frequency oscillator is
attached to the IC. Using the
higher frequency allows greater
maximum scan speeds, but
causes the IC to draw slightly
more supply current. If the state
of the FRQ pin does not match
the actual oscillator, beeper
tones, LED flash length, parallel
port timing, and serial port baud
rates are adversely affected.

IOM Pin
The IOM pin selects between the
serial and parallel I/O mode of the
IC. Depending on the state of the
IOM pin, definitions of several
configuration pins change or
move to new positions.
