E6248 [Microchip]

Atmel® offers market-proven technology for implementing nonmechanical buttons, sliders, and wheels on any touch-sensitive device. These integrated circuits (ICs) enhance the user experience with excellent precision and reliability. They also deliver superb low-power characteristics, a critical requirement for today’s battery-powered handheld and mobile devices. The technology supports simple 1–10 button configurations (self capacitance) as well as more complex scanned-matrix configurations (mutual capacitance) of up to 48 buttons at very low cost per button. In addition to the application specific chips, Atmel offers the QTouch® Library for embedding buttons, sliders, and wheels into the industry-leading AVR® microcontrollers and Atmel AT91SAM.
