August 17, 2011 - Microchip Technology announced the mTouch AR1100 Analog Resistive USB Touch-Screen Controller. The 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 controller is available as a turnkey chip or board product, supporting all 4-/5-/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. Touch input is fast becoming a standard user interface.
Resistive touch provides the advantages of easy integration, low total system cost and acceptance of finger, glove or stylus input, to meet the needs of applications such as medical devices, industrial controls, handwriting or signature capture, and other touch-input mechanisms. Additionally, USB communication is the industry standard for attaching peripherals to a computer. The AR1100 is an easy-to-integrate touch-screen controller that meets all of these needs in a single-chip solution. It also features advanced calibration options for alignment and linearization, enabling superior accuracy for 4-, 5- and 8-wire touch screens, as well as highly accurate button pressing for critical applications with tight spacing.
Availability
The AR1100 controller is available in 20-pin SOIC, SSOP and QFN packages in 10,000-unit quantities. The AR1100 is also available as a board product in production quantities. The mTouch AR1100 Development Kit (part # DV102012) includes an AR1100 production-ready PCB, with a USB cable and a 5-wire analog-resistive touch screen, enabling designers to quickly connect and test this advanced touch-screen controller.
