The ScreenCoderTM USB IC UR7HCTS2-U860 is the irst single IC that seamlessly nterfaces ANY 4- or 8-wire\ sistive touch screen to a USBequipped ystem. It is also the irst touch screen controller IC on he market designed to ccommodate a very wide range of ize, capacitance and resistance of - or 8-wire touch screens, roviding a universal performance
solution among different OEMproducts and touch screenvendors. This unique feature of theIC UR7HCTS2-U860 provides OEMs with a wide ariety of interchangeable touchscreen options.
Unlike digitizers, the creenCoderTM USB UR7HCTS2-U860 integrates adigitizer with a controller thatperforms all touch detection, noisefiltering, error elimination andprovides the host with processedand stable positioning data overUSB. Semtech's unique motionalgorithms provide high resistanceto RF and other noise sourcesresulting in precise, non-jitterycursor control.Ideal application for theScreenCoderTM USB UR7HCTS2-U860 includeportable devices, interactive kiosksand industrial / custom displayswith integrated touch screens.
The universal features of theScreenCoderTM USB UR7HCTS2-U860, asimplemented in both the systemand the sensor interface, reduce
the development effort and cost oftouch input based systems. TheScreenCoderTM USB is available ina slim, 36-pin SSOP package.
