ATtiny261/461/861 Preliminary Summary (19 pages, revision B, updated 11/06)

      ATtiny261/461/861 Preliminary (236 pages, revision B, updated 11/06)

AppNote:

AVR077: Opto Isolated Emulation for the DebugWIRE(9 pages, revision A, updated 1/08)
This application note describes how to implement an optoisolated interface for the DebugWIRE. This device could help the debug of applications with non isolated power supply like ballast, motors, vacuum cleaners, refrigerators, etc.

AVR040: EMC Design Considerations(18 pages, revision D, updated 6/06)
This Application Note covers the most common EMC problems designers encounter when using Microcontrollers.

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.

AVR469: MC301 Hardware User Guide(21 pages, revision A, updated 4/09)
The MC301 is the device board for ATtiny861 AVR® microcontroller which can be connected to the general-purpose power stage board MC300 for driving brushless DC, brushed DC and stepper motors. This board is also designed to be connected on any other driver board which could share the same interface. Power and all signals needed for a power stage board are available on the right side of the board. Jumpers allow demonstrating sensor or sensorless modes of motor control. Finally, interface like USB or Atmel DB101 Display module is also available.

AVR498: Sensorless control of BLDC Motors using ATtiny261/461/861(20 pages, revision A, updated 7/09)
This application note describes how to implement a brushless DC motor control insensorless mode using the ATtiny861 AVR® microcontroller.In this document, we will give a short description of brushless DC motor theory ofoperations, we will detail how to control a brushless DC motor in sensorless modeand we will also give a short description of the ATAVRMC301 and ATAVRMC300boards used in this application note.

      AVR000: Register and Bit-Name Definitions for the AVR Microcontroller(1 pages, revision B, updated 4/98)
This Application Note contains files which allow the user to use Register and Bit names from the databook when writing assembly programs.
