Microchip Technology Inc. has launched the mTouch AR1100 analog resistive USB touchscreen controller, which builds upon the AR1000 touchscreen controller series.

The AR1100 controller is a high-performance, USB plug-and-play device that offers advanced calibration capabilities as a USB mouse or single-input digitiser, according to Microchip. The controller is available as a turnkey chip or board product, supporting all 4-, 5-, 8-wire touchscreens, with free drivers for most major operating systems.

The device is a suitable solution for customers who want a drop-in touch controller to universally support their entire standard resistive-touch portfolio, Microchip said.

AR1100

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 touchscreen controller that meets these needs in a single-chip solution. It also features advanced calibration options for alignment and linearization, enabling accuracy for 4-, 5- and 8-wire touchscreens, as well as accurate button pressing for applications with tight spacing.

AR1100

The AR1100 controller is available in 20-pin SOIC, SSOP and QFN packages today 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 touchscreen, enabling designers to quickly connect and test this advanced touch-screen controller.

All products can be purchased today and samples of the controller can be ordered at the company's website.
