I've trying to find out what's the program memory data retention with no success. A search in the forums reveals only answered similar questions. Then I did a search on google and found some documents from ATMEL, but I really can't get any meaningful value out of them!
I got to these documents:
http://www.atmel.com/quality/acr... (this one from 2007)
But these seem to be just test reports without values that, at least I, can't translate to the usual "years".
I also took a look at the FAQs in ATMEL support center but nothing.
Has anyone any information of this?
