Interesting. So that's (likely) the megaAVR 0-series family complete. You can't go bigger than 48k because of the way the memory is mapped, it probably doesn't make sense to go smaller than 8k, it also probably doesn't make sense to go more than 48 pins, and you'd never fit all the functionality is less than 28 pins.
The tinyAVR 1-series is looking to be complete, unless there are plans for 48k devices, as is the tinyAVR 0-series.

If you say so. I always thought that Microchip's "Core Independent Peripherals" and Atmel's "Event System" and/or "Sleepwalking peripherals" were approximately the same thing. (though I haven't looked at either one in enough detail to see if there are any important differences.)
In '11, became aware of the Charge Time Measurement Unit (CTMU) in some PIC18F where the CTMU is sensing touch buttons while the CPU sleeps.
Atmel QTouch is implemented by library software (CPU) that was improved by some PB megaAVR with the Peripheral Touch Controller (PTC)
AVR32 UC3L has an autonomous touch button hardware interface (Capacitive Touch or CT) to wake the CPU.
Waking up a capacitive touch-sensing device with an MCU peripheral
Nithin Kumar Mada and Harsha Jagadish, Microchip Technology - July 27, 2011
When a capacitive touch screen goes into sleep or standby mode to save energy, how can you design the system to wake up quickly without degrading its performance or burning a lot of power. Here are two options: a traditional method and a new MCU-based method.
How they run it at 16MHz ? I thought it will run at 20MHz. Is the schematic available ?

No, but I've been playing with the code using an Xplained Pro board.
That's the lovely thing about Open Source - you can analyze it, criticize it, submit bugs, even write fixes, all without actually contributing to the vendor's revenue stream!

TopIt seems I also need to add the ATmega1609, ATmega1608, ATmega809 and ATmega808 to the avrdude.conf file in my programmer.
BTW, tiny3204, tiny3206 and tiny3207 are also missing in my avrdude.conf, but they don't seem to be planed even as future products.

TopCouldn't quickly locate the schematic of Arduino Uno WiFi rev2.
Its competitor is AVR-IOT WG Development Board
AVR-IOT WG's mega4808 is on page 3 at B3 :
http://ww1.microchip.com/downloads/en/DeviceDoc/AVR-IoT_WG_Schematics.pdf
To megaAVR 0-series UARTs were added autobaud (BREAK, SYNC, data) and FBRG.
AVR-IOT WG's nEDBG SAMD21 (page 2, C5) has access to USB SOF for creation of an accurate internal clock.

TopATmega4809 Curiosity Nano
has separate LDO for mega4809 and nEDBG SAMD21 such that mega4809 VCC can be nearly USB VBUS.

TopAnd man, that power supply just keeps getting more and more complicated. Six transistors, now! (oh wait - the opamp is gone...)
Am I missing something? Were there spectacular problems with the old design? Is there something wholy awful about a couple of diodes?
(and you'd think that someone would have put this whole "USB or external power to 5 and 3V @500mA total" on a single chip/module by now...)

It is very strange to see "coming soon" at the Arduino store, as if it had not arrived !
But it is available at Mouser ...
