ATmega48/88/168 Automotive (341 pages, revision H, updated 2/09) AVR042: AVR Hardware Design Considerations(14 pages, revision F, updated 4/08)This Application Note covers the most common problems encountered when switching to a new microcontroller architecture like the AVR.Solutions and considerations for the most common design challenges are covered.
AVR053: Calibration of the internal RC oscillator(15 pages, revision G, updated 05/06)This application note describes a method to calibrate the internal RC oscillator and targets all AVR devices with tunable RC oscillator. Furthermore, an easily adaptable calibration firmware source code is also offered. This allows device calibration using AVR tools, and it can also be used for 3rd party calibration systems, based on production programmers.
AVR055: Using a 32kHz XTAL for run-time calibration of the internal RC(16 pages, revision D, updated 7/08)This application note describes a fast and accurate way to calibrate the internal RC oscillator using an external 32.768 kHz crystal as input to an asynchronous Timer/Counter.
AVR140: ATmega48/88/168 family run-time calibration of the Internal RC oscillator(12 pages, revision A, updated 09/06)This application note describes how to calibrate the internal RC oscillator via theUART. The method used is based on the calibration method used in the Local InteconnectNetwork (LIN) protocol, synchronizing a slave node to a master node at thebeginning of every message frame.
AVR317: Using the USART on the ATmega48/88/168 as a SPI master(10 pages, revision A, updated 09/04)Some applications might need more than one SPI module. This can be achieved using the new Master SPI Mode of the ATmega48/88/168 USART.
AVR322: LIN Protocol Implementation on Atmel AVR Microcontrollers(21 pages, revision A, updated 12/05)The LIN protocol is introduced in this application note, along with its implementation on Atmel Automotive AVR microcontrollers.
