4. General Information
4.1 Resources
A comprehensive set of drivers, application notes, data sheets and descriptions on development tools are available for
download at www.microchip.com
4.2 Code Examples
This documentation contains simple code examples that briefly show how to use various parts of the device. These code
examples assume that the part specific header file is included before compilation. Be aware that not all C compiler vendors
include bit definitions in the header files and interrupt handling in C is compiler dependent. Please confirm with the C com-
piler documentation for more details.
4.3 Capacitive Touch Sensing
QTouch Library provides a simple to use solution for touch sensitive interfaces on AVR microcontrollers. The QTouch
Library includes support for QTouch
®
and QMatrix
™
acquisition methods.
Touch sensing is easily added to any application by linking the QTouch Library and using the Application Programming
Interface (API) of the library to define the touch channels and sensors. The application then calls the API to retrieve chan-
nel information and determine the state of the touch sensor.
The QTouch Library is free and can be downloaded from the website. For more information and details of implementation,
refer to the QTouch Library User Guide – also available from the website.
4.4 Data Retention
Reliability Qualification results show that the projected data retention failure rate is much less than 1 ppm over 20 years at
85°C or 100 years at 25°C.
