Sensor Controller Resistive Serial 20-Pin SOIC T/R

The Microchip mTouchTM AR1100T Analog Resistive USB and RS-232 Touch Screen Controller represents a feature-rich, fully-integrated universal touch screen controller solution. The AR1100 automatically selects between USB and RS-232 communication protocols, as well as supports 4, 5 or 8-wire analog resistive touch screens from any of a variety of touch screen manufacturers. The AR1100 dynamically adapts to the various touch screen electrical characteristics such as sensitivity, contact resistance, and capacitance to provide optimal performance with minimal design time. Building on the AR1000 series, the new AR1100 offers customers an easy-to-integrate solution for low-cost, high-performing resistive touch with the advantages of USB plug and play, support for USB mouse or digitizer, advanced touch response and accuracy, field flash updatability, and free drivers for most operating systems to enable low risk designs for a wide variety of touch sensing requirements. The AR1100 supports large displays like industrial controls, self-service kiosks, and POS terminals, as well as smaller tablet displays, handheld consumer devices, and medical devices.
