UR6HCPS2-SP40-FG

Manufacturer Part Number
UR6HCPS2-SP40-FG
Description
Manufacturer
Semtech Corporation
Datasheet
The PS2Adapt
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 PS2Adapt
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-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.
Each of four external PS/2 ports
also support more than 140 key
scan codes including international
language keys, internet keys, and
power keys. The PS2Adapt
offers 4 reserved pins for LED
functions, their functions can be
customized by Semtech.
PS2Adapt is a trademark of Semtech Corp. All
other trademarks belong to their respective
companies.

... To assure fast transmission, the system must assert _RTS low as soon as possible. If the system is ready to receive the data, it doesn't have to raise _RTS between packages. The UR6HCPS2-SP40 checks _RTS after every byte transmission. If _RTS returns to high, it means that the transmission was unsuccessful. The IC will raise _CTS to abort the transmission and the entire package will be re- transmitted ...

... MSB to LSB; if CONF0 pin is low the sequence is LSB to MSB. The SDATA pin outputs data every time the transfer clock changes from high to low level. Protocol: 1. The UR6HCPS2-SP40 asserts _ATN low to indicate that a mouse packet is waiting for transfer. 2. The Host asserts _SS low to indicate that it is ready to receive data. _SS low means the system selected SPI PS2Adapt TM as its communication device ...

... POWER MANAGEMENT Modes of Operation The UR6HCPS2-SP40 has two modes of operation relating to its power consumption. The "Stop" mode is the lowest power consumption mode. In this mode, the oscillator is stopped and the IC consumes only 1 µA of leakage current. This is the default mode to which the IC will revert to when it is idle. The " ...
