UR7HCTS2-S840

ScreenCoderTM UR7HCTS2-S840 High-Performance, Low Power Touch Screen Controller/Digitizer HID & SYSTEM MANAGEMENT PRODUCTS, MOUSECODERTM FAMILY DESCRIPTION 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 complicated software drivers and no processing burden is placed on the CPU. Due to the IC’s superior data processing and sampling rate, the ScreenCoderTM SPI/Serial is ideal for use in systems requiring handwriting recognition. Patented-power management techniques are also implemented so that the IC only consumes 1uA of current most of the time, even with the external mouse connected. The IC operates at 3 to 5 Volts. Features of Semtech’s motion algorithm include resistance to RF and other noise which provides smooth and precise motion control. The UR7HCTS2-S840 also works flawlessly with any 4 or 8-wire touch screen, regardless of size or manufacturer. The cost-effective solution requires few external components, allowing for a simple and real estate saving implementation.
