ScreenCoderTM UR7HCTS2-P840 High-Performance, Low Power PS/2 Touch Screen Controller/Digitizer HID & SYSTEM MANAGEMENT PRODUCTS, MOUSECODERTM FAMILY DESCRIPTION The ScreenCoderTM PS2 is a highperformance IC that interfaces any 4 or 8-wire resistive touch screen to the standard PS/2 mouse port. Low-power and tiny, the single IC is ideal for portable systems, web phones and interactive kiosks. It offers an advanced algorithm for enhanced motion control as well as an extra port for hot-plug connection of an external PS/2 pointing device. Both the touch screen and the external device can be operated concurrently without any penalty. The UR7HCTS2-P840 is equipped with a special command protocol that enables the touch screen to operate in either relative (mouselike) or absolute positioning mode.
