Hi everybody
what's difference between ATMEGA8-PU and ATMEGA8-16PU?
i couldn't found separate datasheet for both.

According to the datasheet, the first is not a valid partnumber. Where did you get it from?

Well, one of my friends ask it in ECA forum but i couldn't found an answer for it. the link of question:

If you check the ATMEGA8 data sheet under the title ORDERING INFORMATION then you will find all avaliable part numbers.

My farsi is not up to chuff, so reading that forum is of little use to me.

The fact you couldn't find an answer tends to suggest something, yes? Where did your friend get this part number from? Besides, it doesn't take much mental power to conclude the speed has been omitted.

lets i ask this subject to him and next answer to you.

Guys,
who can put a picture of his atmega8a(please no iranian)?
today, i looked to my atmega8a. they wrote this on my MCU: ATMEGA8A-PU!!! :shock:

You can see exactly what that is in the back of the data sheet. The data sheet lists all of the available part numbers. It will tell you something about temperature range and maybe clock rates and other numbers that specify the package (DIP, etc).

What ever anyone else may tell you, that is the definitive list.

Thanks Jim,
but you can really see this partnumber=ATMEGA8A-PU?
unfortunately, i haven't a good camera for photography.

See it where - on the chip or in the spec sheet? On the chip, it is on the top, and is typically a few mm tall. It may not alway be very clear. If you use a low power magnifier, you should be able to see it with little problem.

The DIP packages often have an Atmel logo. One Mega32 I have says in white printing:

ATMEL
ATMEGA32
16PU
06278

Ignore the 4th line. This is for an AtMega32-16PU

I cannot see yours because my eyesight for such things is limited to a meter or less, not thousands of kilometers.

Thanks Jim,
Coincidentally i have an ATMEG32A. on it wrote:
ATMEL(the brand of Atmel)
ATMEGA32A
PU
1150

and for ATMEGA8A wrote:

ATMEL(the brand of Atmel) 1222
ATMEGA8A-PU

i attached a picture by high resolution(the size of picture is 1507*1943).

But you did not ask about this part...you asked about

ATMEGA8-PU and ATMEGA8-16PU

...and you were told ...
Quote:

So, what >>is<< your question?

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.

My main question was this:
"what's difference between ATMEGA8-PU and ATMEGA8-16PU?"
that also the Kartman said:

Quote:

Lee,
in my country, we just have this type that i can't find it at datasheet. this subject is very odd! i think in this case, the picture is very obvious. already, when i said you or other guys that we(iranian) have fake MCU, you wouldn't believe.

Rohalamin, I know I "am not important" to you, but still..

Starting with the "ATmega8":
Pay attention to details. Your photo shows a ATmega8A-PU.

Again, ATmega8-PU seems to be a non-valid part number. Have you ever actually seen one (without the 'A')?

The ATmega8A has a separate data sheet (it is not the ATmega8 data sheet). Just go over to Atmels site and get that data sheet.

Now for the "ATmega16":
Your photo shows an ATmega32A-PU. So what is it you want to compare the ATmega8A-PU with? An ATmega32A-PU or an ATMEGA8-16PU?

If it is the ATmega8-16PU then compare the ATmega8A data sheet with the ATmega8 data sheet.

If it is the ATmega32A, then compare the ATmega8A data sheet with the ATmega32A data sheet.

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

ATmega8(L) datasheet: ATmega8L-8PU PDIP-28

ATmega8A datasheet: ATmega8A-PU PDIP-28

Looking at a Chinese USBASP board: ATmega8-8AU TQFP-32

So it appears that there are device with inconsistent part numbers.

Your "1222" means manufactured in week-22 of 2012.

I doubt that anyone would ever bother to counterfeit mega8 chips. Especially the PDIP versions.

David.

Interesting! "ATmega8-8AU" is not a part number listed by Atmel, if I read them correctly. Now I need to go have a look at one of my chinese USBASPs..
