The UR6HCPCS is an easy-to-use
single chip protocol interpreter that can
link a AT/PS2-compatible User Input
Device (UID), such as a keyboard,
mouse, bar-code reader, etc., to any
host system equipped with a serial or
parallel port. The UR6HCPCS emulates
all the functions of the 8042 keyboard
controller which typically resides on the
AT/PS2 motherboard. In addition, the
protocol interpreter implements all
levels of the keyboard BIOS protocol
that handles two-way communication
with the keyboard, performs error
detection and elimination, and can
translate all scan code information into
an ASCII format understandable to
application programs.

The UR6HCPCS is ideal for proprietary system designs needing to interface PC-
compatible UIDs for data entry purposes.
Because the UR6HCPCS allows any system with a serial or parallel port to interface
inexpensive, off-the-shelf UIDs without regards to that system’s architecture or
firmware, system designers and integrators can achieve maximum data entry
performance without needing to spend the development time and costs associated
with custom input device designs.
The UR6HCPCS also supports a set of
commands from the host system that
can be used to control communication
and functional characteristics of the
UID. In a single chip, the UR6HCPCS
offers the input device functionality
previously achieved only by utilizing
several ICs and BIOS modules set on a
AT/PS2 motherboard.
As the UR6HCPCS implements all levels of input device protocol, no complicated
software drivers are needed - translating in further savings for the system developer.
The UR6HCPCS is also highly suitable for use in systems where multiple, concurrently
operable UIDs are needed, such as Point of Sales Terminals, multi-user systems,
industrial control systems, etc.
