I've recently been looking at an old project, which used a Mega8, I've noticed that the Mega8 (and 8L) is in the process of being replaced by the Mega8A.
Usually when a product is replaced, Atmel list the changes, but for the 8 to 8A I can't find a list of changes.
After a quick scan of the Datasheets. I can't see any significant changes. Are there any or is the Mega8A designed as a drop in replacement?.
Also I can't find anything from Atmel announcing the change, however I sure that is just because I'm looking in the wrong place (I think/hope).
