The DeskCoder
TM
keyboard encoder
functions as a versatile, low-power
desktop keyboard encoder, while
providing two bi-directional
channels for communication with a
BIOS-compatible system as well as
any optional keyboard-compatible
devices, such as a 101/102/104
desktop keyboard, OCR, barcode
reader, etc.
The DeskCoder
TM
fully supports the
IBM standard keyboard communi-
cation 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 128
keys organized on an 8 x 16 matrix.
In addition to the system’s keyboard
communication port, the UR5HC418
provides a fully functional keyboard
input port that can be used by a
standard 101/102/104 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 DeskCoder
TM
is ideal for use in
low-power, low-cost and high-
reliability AT / PS/2 - compatible
keyboard designs.
Note: A version of the IC that
supports the PC/XT protocol is also
available. Contact Semtech for
more information.
Implements all functions of a
101/102/104 keyboard
