Hi,

I'm looking for some Atmel PDF document about how to read description on AVR packages.

for example:

ATmega8-16PU
1136D <--- ????

I think it is year (2011) and week (36) - am i right?

Regards

Some info here: https://www.avrfreaks.net/index.p...
See this, and the linked thread:

Note that very small devices may not have enough room for full labeling.

Perhaps, also, as Atmel is now using new fabs the identification system might have changed.

So P stands for low power, A stands for Automotive/Affordable (they run at higher temperatures and are cheaper) The 10U has a max speed of 10, a 20U has a max speed of 20 MHZ.

That's what I've gathered after working with them for 4 years now

I think a v indicates the new 1.8v parts.

If you don't know my whole story, keep your mouth shut.

Not exactly. For example, "A" can be the new fab/die change or a packaging suffix. "A" is not "automotive temperature range" in any model I've every seen.

While your 10U/20U isn't incorrect, newer generations (all the A dies?) have no max speed number in the part number.

"P" is PicoPower --- and also a packaging suffix.

Even veterans can get fooled--there are a couple threads about "-AQ" suffixes with scant information anywhere. (Those are neither "automotive temperature range" nor "affordable" regardless of the "A".)

LOL--apparently it indeed was in the good-old-days when other temperature ranges were C/I/etc. :

So, an A could be automotive temperature range, packaging option, or die shrink. Thus, if they did a die shrink on a Mega8 that was formerly classified by the C/I temperature range and did not make it lead-free and in the automotive temperature range in TQFP, it would be an ATmega8A-AA.

After visiting digikey, they have some different stuff than I remember seeing before, in particular this bad boy

ATMEGA88PA-ANRCT-ND

ANRCT seems to mean that it can go up to 100C where as most of the other stuff only does 80C
