You're absolutely right. This member is stupid. Please help.
Interesting. The datasheet doesn't seem to cover the 44-pin and 64-pin parts.
a secret chip :lol:
That must be just a mistake on that web page. R in the end means tape and real (instead of tray), thus AN and ANR should be the same except the ordering format. Now one is 44 pin (A4U?) and the other 64 pin (A3U?).
Digikey has ATXMEGA128A1U-AN in stock, claiming it is a TQFP-44 package. And the datasheet on their site is the same as the one from Atmel, where the 44-pin version is not mentioned. Indeed it seems to be a secret (yet purchasable) chip. Weird.

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.
Aren't all Xmega 1 100 pin (in TQFP); 3 is 64 pin; 4 is 44 pin; 5 is 32 pin?
Interestingly, they are now gone from Atmel's website (I suspect that some Atmel actually people read some of these posts). But curiously, they are still available from Digikey. I almost feel like buying some, just so I can own a few microcontrollers that never existed. :lol:

Look at the DigiKey entry again. While it says 44 pin, lok further and see the 78 I/O. If you can get THAT out of a TQFP44... :twisted:
i think the only difference between atxmega128a1u-au and
ATXMEGA128A1U-AN is the working temperature range which is -40 to 85 degrees for AU and -40 to 105 degree for AN version (in celcius)...... and rest all specs are the same and both are in 100 TQFP package
