Xtrinsic capacitive and resistive touch-sensing platform (CRTouch) enables resistive touch screens to handle basic gesture recognition. CRTouch allows also the addition of up to four capacitive electrodes to your system; all packaged on a 5 x 5 mm lead-free 32-pin QFN. It supports 4- and 5-wire touch screens and communicates over UART and IIC communication protocols.

CRTouch is the industry's first device that combines 4- and 5-wire resistive screen controller with basic gesture recognition, and up to four capacitive touch-sensing electrodes, all encompassed in a single integrated circuit, allowing the implementation of both technologies reducing space, software development cost and time to market.
