PS2AdaptTM UR6HCPS2-SP40
Converts PS/2 Data to Serial or SPI
HID & SYSTEM MANAGEMENT PRODUCTS, PROTOCOL INTERPRETER FAMILY
DESCRIPTION
The PS2AdaptTM is a Zero-PowerTM
protocol interpreter that can link an
AT/PS/2-compatible Human Input
Device (HID), such as a keyboard,
mouse, bar-code reader, etc. to any
host system equipped with either
Asynchronous Serial Interface (ASI)
or the Serial Peripheral Interface
(SPI).
The IC was designed specifically
for RISC-based portable devices
that are limited to ASI and SPI
interfaces. The PS2AdaptTM allows
designers to easily connect PS/2
devices to their system.
The UR6HCPS2-SP40 emulates all
the functions of the 8042 keyboard
controller which typically resides on
the AT/PS/2 motherboard. The
Zero-PowerTM PS2AdaptTM will power
down even between
key presses and bewteen mouse
reports. Typical power
consumption is only 1 µA operating
between 3-5 Volts.
The UR6HCPS2-SP40 boasts 4
external PS/2 ports that support the
hot-plug connection of an external
PS/2 keyboard or mouse,
including MouseWheel, 5-button
mice and touch screens in absolute
mode.
FEATURES
• Typically consumes less than 1 µA
• Interfaces the host system via
either Asynchronous Serial
Interface or Serial Peripheral
Interface (SPI)
• Jumper selectable interface and
Baud rate
• Offers four PS/2 ports for the hot-
plug connection of external
keyboards or mice including
MouseWheel, 5 button mice and
absolute mode touch screens
• Easy to use, one way
communication protocol
• Operating voltage between 3
and 5 Volts
• Custom versions available in
small or large quantities
• Small 7x7 mm package to
accommodate slim designs
APPLICATIONS
• H/PCs
• Web Phones
• PDAs
• System Legacy Support
