AR1100 mTouch™ USB Controller

Microchip AR1100 mTouch™ USB Controller

Microchip's mTouch™ analog resistive USB touch-screen controller

Building upon the AR1000 Analog Resistive Touch-Screen Controller series, Microchip's AR1100 controller is a high-performance, USB plug-and-play device that offers advanced calibration capabilities as a USB mouse or single-input digitizer. The new controller is available as a turnkey chip or board product, supporting all 4-, 5-, and 8-wire touch screens, with free drivers for most major operating systems. The AR1100 is an ideal solution for customers who want a drop-in touch controller to universally support their entire standard resistive-touch portfolio.   AR1100 Datasheet
