3. Resources

A comprehensive set of development tools, application notes and datasheets are available for download on

http://www.atmel.com/avr.

Note: 1.

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.

5. About 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 compiler documentation for more details.

For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions must be

replaced with instructions that allow access to extended I/O. Typically “LDS” and “STS” combined with “SBRS”,

“SBRC”, “SBR”, and “CBR”.

6. Capacitive touch sensing

The Atmel® QTouch® Library provides a simple to use solution to realize touch sensitive interfaces on most Atmel

AVR® microcontrollers. The QTouch Library includes support for the QTouch and QMatrix® acquisition methods.

Touch sensing can be added to any application by linking the appropriate Atmel QTouch Library for the AVR Micro-

controller. This is done by using a simple set of APIs to define the touch channels and sensors, and then calling the

touch sensing API’s to retrieve the channel information and determine the touch sensor states.

The QTouch Library is FREE and downloadable from the Atmel website at the following location:

www.atmel.com/qtouchlibrary. For implementation details and other information, refer to the Atmel QTouch Library

User Guide - also available for download from the Atmel website.
