Hi guys,
For the last couple of months there is a permanent lack of AVR microprocessors, and prices are crazy. Now for simple AVR I have to pay more than for a 32-bit, full featured processor. Somebody in Atmel has a serious brain damage. Do anybody know when the situation will change, or maybe it's time to change to ARM or PIC ?

A lot of parts are currently on allocation. Not only Atmel is affected.

Can I respectfully suggest you do a thread search for "availability" (especially in the OT forum) - there's only been about 10 or more threads about this in the last 3 months already. There's little point in continuing to flog the dead horse.

I'm not having any problem finding what I use, if fact both DigiKey and Mouser have thousands each of a large variety of AVRs. Yes, some devices are on allocation, but I can't remember a time in my career where that couldn't be said about some part for every IC mfg out there. Would anyone claim that there aren't now nor ever were any ARM or PIC part on allocation? Only someone deluded or intent on FUD would make such a claim.

That's a bit of a broad statement, don't you think? With ~100 models and different flavours and packages of those, "a permanent lack of AVR microprocessors" implies that none are available? No-one is able to buy any AVR micro, and all of our production at board houses is on hold because of that, and they haven't notified us?!? I must check on that immediately!

Yes, indeed, there are "spot shortages" in certain models/families/packages. And it can be rankling when for the past few years virtually every mainstream model/package was in stock at domestic distributors.

Adding to the above, it ain't just AVRs. Try to get a supply of relays....

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

Yes, it’s a broad statement, but unfortunately it’s true. In Poland, where I live, none of the big electronic suppliers have any AVR. To be honest, they have, one or two types. The rest are ‘on special order’, and nobody can say when it can be shipped.
Just take a look www.tme.eu, www.farnell.com and so on. Ok, you can get ATMega128 for 23 pounds + shipping costs. At the same time, there is a lot of different cheap ARM and PIC models.

So could you edit the title to include the word Poland?

The same situation is in the whole Europe. TME and Farnell are a European distributors.

OK, I'll bite.

-- I cannot comment on the price that your supplier chooses to charge, especially quantity 1 prices. Nearly irrelevant?

-- pl.farnell.com shows 108 items of "ATmega" in-stock. I did not scroll through all the pages, but for the first pages the "1" models seemed to be in-stock in several packages: 128, 1280, 1281, 162, 164, 165, 169, ...

So "permanent lack"? Hardly.

Finding the distributors in Poland from the links at www.atmel.com Farnell and tme aren't listed. What kind of stock do the authorized distributors have?

Yes, as others have said in this thread and previous discussions, component availability is spotty. And it is frustrating after the well-stocked shelves of the past few years. Hardly a "permanent lack".

Check the prices. ATMega128x series cost above 10 pounds, if you will buy at least 100 pieces. Above 22 pounds if you will buy 1-10. Do you think it’s normal? For a fraction of that price I can buy better equipped ARM or PIC. Half of the items are. Don’t understand me wrong, I’m a great fun of Atmel, but most of their chips seems to exist only virtually as datasheets. And because I build real devices, I need real chips.
And BTW, I’ve checked distributors listed on Atmel webpage – the same. They only have a couple of not so popular chips. The date of delivery of rest of them is in the misty future.

Only 27 different types are on stock.

What do you mean "different types"? Different model numbers?

If so, what is the total number of different ATmega model numbers? On the Atmel devices page, I count about 30 different ATmegannn with various suffixes. Let's make it 36 and assume you sorted and counted all 108 of the Farnell (only ONE supplier and not listed as a disti) hits and came up with 27. That means to you that 75% of all models available, in an average of 4 flavours each, is a "permanent lack"? [Give it up--you are never going to reason or prove this one. Out-of-stock frustration and venting is certainly understandable. But it always makes me rise to the bait when superlatives are used.]

Now on to pricing. You are picking one model, and one supplier, and somehow holding up this pricing as an example of "problems with AVR availability". If Charmin toilet paper is too high a price at my corner convenience store, I look for it at the department store or discount store. If they are out, I look at equivalent substitutions or look at other outlets (in this case, I do stock checks and use OctoPart and FindChips to find distributors with stock)

I don't know; what do you consider "normal"?

Are you saying AVRs are too high priced? That is an entirely different topic than "permanent lack". They certainly may not have as much "value" as the newer ARM M3 and M0 offerings. Vs. traditional rivals such as PIC? I'd think AVR prices are competitive.

Note that a non-A Mega128 is "old school" and will probably have higher pricing than, say, an equivalent Mega1281. Perhaps good for your example but in the real world I'll be using Mega88P or Mega88PA and not Mega8. (maybe Mega8A but probably not) I'll use Mega164P or PA and not '8535 or '16 or '32 ('324 instead).

I cannot comment on pricing and availability to Poland. I know there have been several curious posts about not being able to get AVRs in India--you'd think with the size of that economy there would be a thriving electronics distribution system.

The cost for repackaging and handling is excessively big when buying single units. Especially stuff like the big atmegas in trays. IC's on tape are a lot easier to snip :)

At Farnell ‘ATMega’ returns 235 positions, of which only 27 are in stock. It’s 11%. So you said that there is no problem with availability? BTW, Farnell is a distributor of JM ELEKTRONIK, a listed distributor of Atmel.
At Digi-Key ‘ATMega’ returns 782 positions, but only 116 are in stock. Impressive result.

Not true for my run. I got 108 in stock. Thus our difference, I guess.

Yep, 108. I repeated the page load from my history file. But I don't know Polish. ;)

As that will pick up all quantities and obsolete flavours, let's consider that 116, as the 108 at Farnell, is about 4 different flavours of 30 numbered AVR Megannn models.

I'm not saying availability is great. I feel your pain, on a regular basis. But the numbers/links we have posted right above are certainly not "a permanent lack of AVR microprocessors".

I just received this from Silica:

http://www.silica.com/fileadmin/Inxmail_Daten/Trendliner/Trendliner_July10/Trendliner_July2010.pdf

They don't sell Atmel devices (I think they are the main Microchip distributor in the UK), although Avnet, their parent company, does, but it makes interesting reading. Microchip seems to have the shortest lead time for MCUs, which isn't surprising.
