UR7HCTS2-S840 Overview
The ScreenCoderTM SPI/Serial is a touch screen controller and integrated digitizer IC designed specifically for RISC-based systems, such as wireless Internet appliances. The small, single footprint IC interfaces the system via either the Serial Peripheral Interface (SPI) or Asynchronous Serial Interface. Unlike simple A/D implementations, the ScreenCoderTM SPI/Serial does not require plicated software drivers and no...
