Atmel 8-bit AVR Microcontroller with 512/1024 Bytes In-System Programmable Flash

Atmel Corporation 

4. General Information

4.1.

Resources

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

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

4.2.

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.

4.3.

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. 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”.

4.4. Capacitive Touch Sensing

4.4.1.

QTouch Library

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 Atmel QTouch and Atmel

QMatrix® acquisition methods.

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

AVR Microcontroller. 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: http://

www.atmel.com/technologies/touch/. For implementation details and other information, refer to the Atmel

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