Are there likely to be any additional "Mega-0" (or maybe "Mega-1"/etc) parts released by microchip?

(Right now there's just that one ATMEGAmm0p sub-series (ATmega808 - ATmega4809 ?))

 

Or did those end up being the AVR-Dx parts after naming strategies were reconsidered?

Hope is megaAVR 1-series as the follow-on to USB megaAVR (long-in-tooth compared to USB PIC)

USB PIC have dual-port RAM like USB megaAVR.

XMEGA's USB device controller shares RAM with the CPU via the four synchronization instructions (atomic)

So, hope there's not an extension of AVRxt.

A guess for the long pole in the tent is the qualification of a second wafer fab; after that qualification then the gate for new products may open.

No as AVR Dx is the follow-on to non-EBI non-USB megaAVR.

(AVR DA, AVR DB, AVR DD ... indecision ... AVR DC?)

Does Microchip provide a chart to compare, descriptively, these families by name (I do NOT mean the selector guide/excel sheet)?

 

They seem to be gunning it all over the map with their odd naming strategy.  I'm still trying to figure out what they call their ICE box.

Yes

There's a method.

Recall PIC though PIC have greater variety of peripherals.

Do you really want to know?

Thanks , though I was looking for something that describes all of their current families (say you had never even heard of AVR):

 

The AVR ATtiny family of chips is a great...   that .... and has....

The AVR ATmega family of chips is a great...   that .... and has.... and also...

The AVR ATXmega family of chips is a great...   that .... and has.... and also...

The AVR ATDA family of chips is a great...   that .... and has.... and also...

etc...etc

 

This might be a "roadmap" diagram, or text document

 

ATtiny1627 family   ...this seems rather odd...is a specific part now a family, like the ATtiny family????!?

If so, what are all of the present families?

 

perhaps Microchip doesn't know??

Possible fit for that.

tinyAVR 2-series; IIRC, only AVRxt with a PGA.

A Microchip Technology applications engineer does know.

Guess they have zero budget for clear marketing materials, one of which would describe & give a basic overview of their different AVR families.
