AVR138: ATmega32M1 family PSC
Cookbook
Features
• PSC Basics
• Waveform Generation using Power Stage Controller
• Code Examples
1. Preamble
ATMEL
®
is introducing a new 8 bit AVR
®
family with the ATmega32M1.
This family embeds an innovative PSC dedicated to motor control applications and led
lighting applications.
Note: This PSC is different that the PSC used in the AT90PWMx family dedicated for lighting.
As it is primarily dedicated for motor control and to simplify its use, it is a merge of the
three AT90PWMx family PSC. The AVR434 ‘PSC cookbook’ is specially dedicated for
the AT90PWMx family PSC and is not applicable for the ATmega32M1 family PSC.
2. Introduction
This application note is an introduction to the use of the Power Stage Controller (PSC)
available in ATmega32M1 family. The object of this document is to give a general over-
view of the PSC, show its various modes of operation and explain how to configure
them. The code examples will make this clearer and can be used as guideline for
other applications. The examples are developed and tested on ATmega32M1.
PSC description and additional information can be found in the data sheet and in
application notes where the PSC is used.
This application note describes waveforms which can be generated by the PSC and
how to program it. It also introduces fault modes and output enable management.
All source files are available on the Atmel website. They are written on GCC compiler,
nevertheless they can easily modified to compile on other compilers.
3. General Description
The Power Stage Controller is a special timer with 3 modules dedicated to drive the
power stage of an equipment or a board. The PSC is logical level compatible and is
able to drive a bridge of power transistors.
The PSC can drive different kind of bridges (DC, Brushless DC, AC motors ...)
