World’s lowest power capacitive touch, the new Atmel QTouch Surface platform builds on the market-proven QTouch capacitive touch button sensing technology supported by Atmel | SMART MCUs. The new solution includes an on-chip peripheral touch controller (PTC), the cornerstone technology that enables higher performance capacitive touch on Atmel MCUs. Consuming less than 4µA, the QTouch Surface technology is perfect for wearables and other battery-powered applications that require a capacitive touch user interface.
