DESCRIPTION

· Freescale's Xtrinsic Capacitive and Resistive Touch-Sensing Platform (CRTouch) integrates functionality across various applications, reducing development costs and simplifying design cycles.

· The platform supports both resistive and capacitive touch screens, enabling basic gesture recognition and the addition of up to four capacitive electrodes.

· It is housed in a compact 5 x 5 mm lead-free 32-pin QFN package, supporting communication via UART and I2C protocols.

FEATURES

· Supports standard X, Y resistive touch screen detection with optional calibration and built-in filter for enhanced stability.

· Capable of four- and five-wire pressure detection and two-touch gesture recognition on four-wire screens.

· Features zoom in/out, rotate direction indication, and angle measurement capabilities.

· Includes four independent capacitive electrodes configurable as keypad, rotary, or slider.

· Offers UART and I2C communication with two selectable I2C addresses and UART baud rate auto-detection.

· Provides an event indicator signal for the host processor and a configurable sample rate up to 200 points per second.

· Compatible with Linux, Android, and PEG, with example code available.

· Operates at 1.8 to 3.6 volts and within a temperature range of -40°C to +105°C.

· Includes normal run, sleep, and shutdown modes to minimize power consumption.

APPLICATIONS

· Ideal for integrating advanced touch-sensing capabilities in consumer electronics, industrial controls, and automotive systems.

· Suitable for applications requiring multi-touch gesture recognition and precise touch input.

· Effective in systems where space and power efficiency are critical.
