The mXT642T uses the latest capacitive touch technologies that Atmel has designed for the highest-performance super phones and tablets. With a revolutionary adaptive-sensing architecture featuring both mutual- and self-capacitance, it enables the highest performance with the industry’s lowest power consumption.

With 640 nodes, the mXT642T touchscreen controller supports up to 8 inches for Android tablets, 7 inches for Windows 8 mobile devices, and up to 6.2 inches for devices with 1.0mm passive stylus.

The mXT642T supports Hover operation, which tracks the position of the finger when it floats within 20mm of the touchscreen. Hover allows user interaction without making a physical contact, and it brings a more dynamic interface to user applications.

Powered by Atmel’s maXStylus™ technology, the mXT642T supports Active Styli with a 1.0mm tip. With up to 256 levels of pressure-sensing capability, Active Stylus enhances writing and drawing experiences by bringing the convenience of pen-like operation to your touchscreen.
