DN003 - AVR sleep modes

Updated: Feb 24, 2005


A short description of the AVR sleep modes and how they are used, including code examples in C and assembly language.

The AVR family of microcontrollers features several sleep modes. The purpose of these modes is to provide a way of suspending program execution when necessary, thereby reducing power consumption.
Each AVR device features more or less sleep modes. This document is intended to summarize the most common ones and their use, thus enabling the reader to select one of the modes and easily implement this choice in application code.
