The mXT641T 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 mXT641T touchscreen controller supports up to 8” for Android tablets, 7 inches for Windows 8 mobile devices, and up to 6.2 inches for devices with 1.0mm passive stylus.

In addition, the mXT641T 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 brings a more dynamic interface to user applications.
