DESCRIPTION The Screen Coder USB IC is the first single IC that seamlessly interfaces ANY 4- or 8-wire resistive touch screen to a USBequipped system. It is also the first touch screen controller IC on the market designed to acmodate 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. 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 APPLICATIONS - Handhelds/Notebooks - Portable Devices PIN ASSIGNMENTS - Interactive Kiosks - Industrial/Custom Touch Screens - Highly resistant to RF and other noise - No digitizer or external A/D necessary - Fully pliant 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 Unlike digitizers, the Screen Coder TM 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 Screen Coder TM USB include portable devices, interactive kiosks and industrial / custom displays with integrated touch screens. The universal Features of the Screen Coder TM USB, as implemented in both the system and the sensor interface, reduce the development effort...
