AVR137: Writing Software Compatible for AT90PWM2/3 and AT90PWM2B/3B (3 pages, revision A, updated 10/06)
Two revisions of AT90PWM2/3 are available. Versions AT90PWM2B and AT90PWM3B are the evolutions of the AT90PWM2 and AT90PWM3. This application note lists the main corrections and differences between the two designs, and showsan example of software that allows to detect which version is currently programmed.

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.

AVR434: PSC Cookbook (32 pages, revision A, updated 10/06)
This application note is an introduction to the use of the Power Stage Controllers (PSC) available in some AVR microcontrollers. The object of this document is to give a general overview of the PSC, show their various modes of operation and explain how to configure them. The code examples will make this clearer and can be used as guide for other applications. The examples are developed and tested on AT90PWM3.

AVR435: BLDC/BLAC Motor Control Using a Sinus Modulated PWM Algorithm (12 pages, revision A, updated 9/06)
BLDC motors are designed to be supplied with a trapezoidal shape current, respectively BLAC motors are designed to be supplied with a sinusoidal shape current. This application note proposes an implementation using the latter with an ATAVRMC100 board mounted with an AT90PWM3B.
