            AT42QT2160 – Touch and Slide Control
                    Microchip's AT42QT2160 is ideal for use as a small control panel processor in battery-driven consumer devices such as mobile phones, personal media players, and other mobile appliances
    

Image of Atmel's AT42QT2160 Touch and Slide Control The AT42QT2160 from Microchip implements 16 touch channels and a slider (using 2 to 8 channels) as well as LED control, IO expansion and a 2-wire serial interface, compatible to the industry standard I²C bus.

The integrated circuit (IC) is ideal for use as a small control panel processor in battery driven consumer devices such as mobile phones, personal media players, PDAs, digital picture frames, and other mobile appliances. It is based on Microchip's QMatrix™ and QSlide™ technologies, has very low power requirements and provides a very wide range of host programmable input/output configurations.

The EVK2160A allows the user to evaluate all functions of the AT42QT2160 touch sense controller. The kit provides a convenient reference design and allows the user to visualize discrete touch buttons or a touch slider LED control.

This kit is for the evaluation and development of applications using the AT42QT2160-MMU (QT2160) 16 key QMatrix IC. In this example, the QT2160 is shown working in a battery powered standalone mode, but can be connected to a PC and/or user application by simple modifications to the EVK2160A evaluation board.
