DESCRIPTION
FEATURES
The LapCoder
TM
is a versatile, low-
power keyboard encoder for
portable systems. The UR5HCFJ 8
provides two bi-directional channels
for communication with a BIOS-
compatible system as well as
any optional keyboard-compatible
devices, such as a 101/102 desktop
keyboard.
The UR5HCFJ 8 fully supports the
IBM standard keyboard
communication protocol; each key
press generates one of the scan
codes designated in the IBM
Technical Reference Manuals.
The keyboard encoder handles
the scanning, debounce, and
encoding of 82 keys organized on
an 8x16 matrix and supports
embedded numeric keypad
functions as well as alternate scan
codes for specific keys, so that a
keyboard with only 82 keys is able
to emulate the functionality of a
101/102 keyboard.
In addition to the system’s keyboard
communication port the UR5HCFJ 8
provides a fully functional keyboard
input port that can be used by a
standard 82/101/102 keyboard or
another 8042-compatible device,
such as an external numeric
keypad, an OCR, or a bar-code
reader. Input from both the matrix
and the external device is
multiplexed and presented to the
system as if it were coming from a
single source.
The features of UR5HCFJ 8 make it
ideal for use in PC/AT/PS/2
laptop/notebook designs that utilize
the Fujitsu FKB7211 low-profile, full-
travel membrane keyboard.
