Atmel Supplier Page
Atmel® provides a broad range of fixed-function microcontrollers to support capacitive touch in a variety of applications. Buttons, sliders, and wheels capabilities are implemented on silicon using two types of patented acquisition methods: QTouch® technology which detects touches by measuring the charge flow at a given point, and QMatrix® technology which detects touch using a scanned passive matrix of electrode sets.
