Sensor Controller Capacitive/Resistive 1-CH I2C 32-Pin QFN Tray

The CRTouch is a Ready Play solution device designed to serve as a four wire and five wire resistive touch driver and a capacitive touch sensing device in a single 32-pin QFN package. It provides all the signal interfacing and processing to calculate X and Y coordinates as well as to detect and process two touch gestures for human-machine interface applications.

• X and Y coordinates calculated from a resistive touch screen with built-in filter to improve stability
• Slide gesture detection for single touch.
• Two touch gesture detection for resistive four wire screens
  • Zoom In and Zoom Out
  • Rotate with clockwise and counter clockwise indication.
• Four capacitive keys in different configurations
  • Rotary
  • Slider
  • Keypad
• UART communication and I2C communication available
• Baud-rate auto detection pin to enable automatic synchronization with any UART baud-rate between 9600 and 115200 bps using the same UART RX pin
• Configurable scanning period that can calculate up to 200 coordinate points per second
• 1.8 to 3.6 volts operation
• 32-pin QFN package
• –40 °C to 105 °C operating temperature
• Normal Run mode, Sleep mode, and Shutdown mode for lower power consumption operation
