1.2.203 (2017-12-15)

Corrected register names for ATmega4809, ATmega4808, ATmega3209 and ATmega3208.

1.2.150

...

Added ATmega4809, ATmega4808, ATmega3209 and ATmega3208.

Two-level (plus NMI) interrupt controller

32KB and 48KB flash (likely unified memory)

28/32 pins for 8, 48 pins for 9

oooh...  Looks like there might even be a DIP-28 !

Certainly gives the impression that the ATtiny's (xtiny's) are limiting out at 16KB and that 32KB, and larger?, will be classified as ATMega, though that conflicts with what Jan (je_ruud) wrote here.  It would be nice to see an actual roadmap!  Microchip|Atmel, are you listening?

 

Seems to also confirm comments in other threads, made by Microchip|Atmel personnel, that indicated there would be no Xplained Pro based on an ATtiny1616 as they are most likely going to produce an Xplained Pro 32xx or 42xx instead.

So, 3 levels of interrupt priority now - nice!

Two years ago the plans were completely different (, and we also had other owners...). Earth spins, plans change and we just have to compensate and make the best out of it.

 

Currently it seems to me (Marketing people are rather unpredictable at times. Or predictably unpredictable...) that what differs the new tiny's from the new mega's is pin count. But you won't find tiny's with >32kb flash. (.. ... Yet? Marketing, you know.)

I'll go with your "predictably unpredictable" assessment.  Guess we will just have to wait and see what pans out.

Or, maybe, what pins out?
