ScreenCoderTM UR7HCTS2-U860
High-Performance USB
Touch Screen Controller / Digitizer
HID & SYSTEM MANAGEMENT PRODUCTS, MOUSECODERTM FAMILY
DESCRIPTION
The ScreenCoderTM USB IC is the
first single IC that seamlessly
interfaces ANY 4- or 8-wire
resistive touch screen to a USB-
equipped system. It is also the
first touch screen controller IC on
the market designed to
accommodate a very wide range of
size, capacitance and resistance of
4- or 8-wire touch screens,
providing a universal performance
solution among different OEM
products and touch screen
vendors. This unique feature of the
IC provides OEMs with a wide
variety of interchangeable touch
screen options.
Unlike digitizers, the
ScreenCoderTM USB integrates a
digitizer with a controller that
performs all touch detection, noise
filtering, error elimination and
provides the host with processed
and stable positioning data over
USB. Semtech’s unique motion
algorithms provide high resistance
to RF and other noise sources
resulting in precise, non-jittery
cursor control.
Ideal application for the
ScreenCoderTM USB include
portable devices, interactive kiosks
and industrial / custom displays
with integrated touch screens.
The universal features of the
ScreenCoderTM USB, as
implemented in both the system
and the sensor interface, reduce
the development effort and cost of
touch input based systems. The
ScreenCoderTM USB is available in
a slim, 36-pin SSOP package.
FEATURES
• Controller & digitizer in a single IC
• Interfaces the system via USB
• Works with ANY 4- or 8-wire
resistive touch screen regardless
of size, material or vendor
• Provides high resolution - 1000
points per axis, enabling IC to
make precise drawing and
signature captures
• Accurate, quick touch response
due to Semtech’s advanced
sampling technology and
algorithms
• Highly resistant to RF and other
noise
• No digitizer or external A/D
necessary
• Fully compliant with USB HID
specifications; works with native
USB drivers including Windows®
98, Me and 2000
• Convienent calibration applet
offered free of charge
• Uses slim 36-pin, SSOP package
• Customized versions available
APPLICATIONS
• Handhelds/Notebooks
• Portable Devices
PIN ASSIGNMENTS
• Interactive Kiosks
• Industrial/Custom Touch Screens

FUNCTIONAL DESCRIPTION
The UR7HCTS2-U860 consists
functionally of five major sections
(see the Functional Diagram on
Page 2). These are the Sensor
Interface, the Power Management
Section, the 16-Bit Timer, the
Oscillator Circuit and the USB
Interface.
OSCILLATOR
This IC has a built-in Oscillator
circuit capable of operations with
an external 6.00 MHz Clock source,
or a Ceramic Resonator (preferably
with built-in Load Capacitors) or a
Crystal with external Load
Capacitors.
POWER MANAGEMENT
According to the USB specification,
if there is no activity of the USB port
for 3 ms, the system is considered
to be in a suspended state. The
ScreenCoderTM USB IC, on
detecting that the system is in
suspend, will check the state of the
touch screen and the right button.
If there is no touch pressure
detected or no button pressed, the
ScreenCoderTM USB enters into the
suspended state. In suspend the
IC fully complies with the USB
specification for the power
consumption, dissipating current
only in the USB-mandated pull-up
for the device identification.

POWER MANAGEMENT (CON’T)
If the system does not allow remote wake-up, the ScreenCoderTM USB will
not send resume messages to the system when it is awoken by activity on
the touch screen or button.
Another technique the IC uses to
conserve power is called remote
wake-up. If the system relies on the
device to perform wake-up, the IC
will send a resume message to the
system when there is activity on the
touch screen or button.
