PixiPointTM Z UR7HCPXZ-P440
Advanced “Click-to-Select”
No-DriftTM PS/2 Force Stick Controller
HID & SYSTEM MANAGEMENT PRODUCTS, MOUSECODERTM FAMILY
DESCRIPTION
The PixiPointTM Z mouse encoder
is a cost-effective, high-
functionality IC designed to
interface the CTS 106, 108 and
109 sensors to the PS/2 port. Ideal
for laptop/palmtop use, the low
power PixiPointTM Z offers an
advanced algorithm for enhanced
motion control. The IC also
enables click, double-click,
MouseWheel action and slow drag
without the need for special
drivers. The IC provides an extra
port for hot-plug connection of an
external pointing device, including
those with built-in Mousewheel.
Both the embedded sensor and
the external device can be
operated concurrently.
The PixiPointTM Z utilizes a special
signal conditioning circuit (US and
International patent pending) which
enables a low cost, simple and real
estate-saving implementation. Just
a few low tolerance external
components are needed.
FEATURES
• Accurate cursor control via
Semtech’s Advanced Motion
Control algorithm
• Click (Select), Double-Click
(Execute), MouseWheel and slow
drag are implemented in the IC –
no special driver support required
• Enables hot-plug connections of
an external pointing device,
including those with MouseWheel
• Offers concurrent operation of
force stick and external pointing
device
• Provides ideal interface for CTS
Series 106, 108 and 109 sensors
• Low power consumption of
typically less than 3mA makes it
ideal for battery-operated systems
• 3-5V operation in extended
temperature range
• Can utilize standard mouse drivers
• Inexpensive, simple and real
estate-saving implementation with
USAR’s proprietary signal
conditioning circuit
• Offers “Clean Stop” so cursor
stops when you want it to
• Compatible with IBM/Microsoft
two-button and Logitech three-
button mouse
• Supports all commands from and
to the system, as defined in the
IBM PS/2 Mouse Communication
Protocol
• Small 32-pin 7mm X 7mm LQFP
package
• Customized versions available
• Royalty-free and cost-effective
APPLICATIONS
• Notebooks/laptops
• Handhelds
• Keyboards
• Instrumentation
PIN ASSIGNMENTS
The IC implements typically
consumes less than 3mA, making it
suitable for use in battery-operated
systems.
PS/2 communication is
bidirectional at 10 kbps. The IC, a
CMOS device operating at 4 MHz,
is compatible with both the IBM
and Microsoft two-button and the
Logitech three-button mouse
protocols. It implements all
commands from and to the system,
as defined in the IBM PS/2 Mouse
Communication Protocol. Custom
versions are also available to suit a
range of applications.
