AVR-Chat

I am looking for a reference book of useful ICs in automation
circuits. Their datasheet and maybe a sample circuit.
Could u help me with a link or a book title?
Tnx

download avrbook.rar from yahoo group-booksbybibin and some books for avr in yahoo group-avrbooks, if you want to do with avr

Thank but I am looking for Motorola or National semiconductor datasheet e-book to find suitable ICs to use or extend my AVR project capabilities. Autodialing, voice recording, etc.

I doubt you are going to find all the info in one place. Also, the devices 
you're seeking may not be made by Motorola or National.

If you have a specific function in mind, I or others here may be able to 
recommend a chip that will work.

I assume you're not in the USA. A good starting place is to get a Digikey 
or Mouser Electronics catalog or spend some time on their websites. Maybe 
when you find the parts in there that will do the functions you want, you 
can download a data sheet from Internet and find a source in your 
country. Actually, the Digikey and Mouser websites have links to 
datasheets for most of the parts they sell.

I have become convinced that a good part of electrical engineering 
consists of a knowledge of what components are available for a particular 
function.  :-)

Well, what I had in my mind was to make my AVR project capable of dialing a phone number in case of an alert, and send a voice message (related to alert type)  over the phone line. I guess at least two ICs are needed: One for dial up functions (busy line, redialing, etc)  and the other for recording/replying voice messages.
 
 Furthemore, I just wanted to 'browse' the most common chips generally used by AVR-programmers/Automation designers.  A dialer and voiceplayer should be among them. Is there such a collection at all? How to know more about it?
 
 Visited Digikey. Was an amazing site, but consists a very broad range of products, a bit puzzling. 
 
 Tnx.

There are various sorts of analog voice storage ICs, and DTMF dialer ICs,
and you'll need a line interface for legal and safety reasons.

Here is an idea.  There is a Yahoo group called the "RAT Ring".  "RAT"
stands for Remote Access Terminal.  Although it is PIC-based, what
they are doing is essentially having the PIC actually perform the
modem functions and other activities with as little reliance on
external hardware as possible.  There is no reason why the same ideas
could not be applied to the AVR.  Also, there is no reason I can think
of that would keep you from using more than one AVR in the project,
i.e., one acts like the modem, the other does the dialling, etc.

Basically, what I am getting at is see how much you can do in software.
Hope this helps.

The Original Poster should know that there really is no set
of "interface ICs commonly used with AVRs". The AVR is a
very general purpose microcontroller and peripheral ICs
that work with other micros also work with the AVR
(mostly).

For dialling, you first need to determine whether you can
use DTMF or do you need "pulse" dial. For the sort of
things you are looking for, check CML Microcircuits in the
UK - http://www.cmlmicro.com/
