Ready Play Solutions Xtrinsic Capacitive and Resistive Touch-Sensing Platform Overview Freescale Ready Play solutions integrate functionality in different applications, allowing customers to add features while reducing development cost—simplifying design cycles and enabling scalability in applications and systems. The Xtrinsic capacitive and resistive touch-sensing platform (CRTouch) enables resistive touch screens to handle basic gesture recognition and allows 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 four- and five-wire touch screens and communicates over UART and I2C communication protocols. The implementation of these technologies enables the CRTouch to help reduce space, cut software development costs and speed time to market. Key Features • Standard X, Y resistive touch screen detection with optional calibration and built-in filter for improved stability • Four- and five-wire pressure detection • Two touch gesture detection on a four wire screen • Zoom in/out • Rotate direction indication and angle measurement • Four capacitive electrodes independent from touch screen may be configured as keypad, rotary or slider • UART and I2C communication available Two selectable I2C addresses UART baud rate auto detection mechanism • Event indicator signal for host processor • Configurable sample rate with up to 200 points per second • Linux®, Android® and PEG integration example code available • 1.8- to 3.6-volt operation • 32-pin QFN package • –40°C to +105°C operating temperature • Normal run, sleep and shutdown modes for reduced power consumption Target Applications • Control panels Xtrinsic and Capacitive and Resistive Touch-Sensing Platform Xtrinsic Capacitive Resistive Touch-Sensing Platform • Human-machine interface CRTouch Ready Play solution System Calibration Sampling Config Capacitive Touch Driver UART I2C SDA/SCL Keypad Rotary Slider Address Select System Communication and Signaling GPIO Comm Selection GPIO VCC GND VCC GND Wakeup Capacitive Electrodes Coordinates Filter Gestures Detection Screen Detection Event • Kiosks CRTouch System Controller Baud Rate Detect • Signature capture devices Resistive Touch Screen RXD/TXD • Point-of-sale terminals Resistive Touch Screen Driver Reset • Keyboard replacement Host MPU/MCU Ordering Information Description MSRP (USD) Part Number CRTOUCHB10VFM $1.82 10 KU Development Tools EVBCRTOUCH $85 Tools and Software GUI No cost Freescale: A Leader in Sensing Solutions Expanding on more than 30 years of sensor innovation, Freescale’s Xtrinsic sensing solutions are designed with the right combination of high-performance sensing capability, processing capacity and customizable software to help deliver smart, differentiated sensing solutions.
