Freescale's Ready Play Solutions integrate functionality to different applications, allowing customers to add features while reducing development cost, simplifying design cycles and enabling scalability in applications and systems.
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.
