The UR7HCTS2-USB Ultimate USB ScreenCoder® is the first single IC that seamlessly interfaces ANY 4- wire, 5-wire, 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 touch screens, providing a universal performance solution among different OEM products and touch screen vendors. This unique feature of the IC UR7HCTS2-USB provides OEMs with a wide variety of interchangeable touch screen options.

Unlike implementations with separate digitizers, the UR7HCTS2-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, jitter-free cursor control.

Ideal applications for the UR7HCTS2-USB include portable devices, interactive kiosks and industrial / custom displays with integrated touch screens.

The universal features of the UR7HCTS2-USB, as implemented in both the system and the sensor interface, reduce the development effort and cost of touch input based systems. The UR7HCTS2- USB is available in a 36-pin SSOP package.
