SH1201 PixiPoint®
Advanced “Click-to-Select”
No-Drift™ Force Stick Encoder
HID & SYSTEM MANAGEMENT PRODUCTS, MOUSECODER® FAMILY
DESCRIPTION
The SH1201 PixiPoint® mouse
encoder is a cost-effective, high-
functionality IC that interfaces a
force-stick sensor to a PS/2 or
serial port. Ideal for laptop or
palmtop use, the low-power
PixiPoint uses an advanced
algorithm for enhanced motion
control. The IC can be configured
as a standard 3-button mouse or
as a wheel mouse. The IC
provides an extra port for hot-plug
connection of an external PS/2
mouse, including one with wheel
function. The embedded sensor
and the external device can
operate concurrently.
FEATURES
• Advanced motion control algorithm
provides accurate cursor control
• Can be configured for PS/2 or
RS232 serial communication with
the host
• Can be configured as a standard 3-
button mouse or a wheel mouse
• Complies with the Microsoft® Plug
and Play External COM Device
specification
• Click (select), double-click
(execute), and slow drag are
implemented in the IC – no special
driver support is required
• Provides built-in profiles to interface
popular force-stick sensors from
several manufacturers
• Supports hot-plug connection of a
standard external PS/2 mouse,
with or without wheel function
• Works with standard Windows®
mouse drivers
• Compatible with IBM force stick
protocol
• CleanStop™ feature means cursor
stops with precision
• In PS/2 mode, supports all
standard PS/2 commands
• Low power consumption:
3.3 mA (typical)
• 2.7 V–5.5 V operation over
extended temperature range
The PixiPoint includes a signal
conditioning circuit for a low cost,
simple and real estate-saving
implementation. Just a few low-
tolerance external components are
needed.
APPLICATIONS
• Notebooks/laptops
• Handhelds
PIN ASSIGNMENTS
• Keyboards
• Instrumentation
Typically consuming less than
3.3 mA, the PixiPoint is ideal for
battery-operated systems.
PS/2 communication is bidirectional
at 10 Kbps. The PixiPoint returns
up to 100 mouse reports per
second, and is compatible with the
standard three-button mouse
protocol and the standard wheel
mouse protocols. It implements all
commands from and to the system
(as defined in the IBM PS/2 mouse
communication protocol).
