Well, LMGTFY:
Core Independent Peripherals are designed to handle their tasks with no code or supervision from the CPU to maintain operation. As a result, they simplify the implementation of complex control systems and give designers the flexibility to innovate.
#5 "If you think you need floating point to solve the problem then you don't understand the problem. If you really do need floating point then you have a problem you do not understand."
... it [mega4809] shares the basic characteristics of the somewhat-stuck-in-time AVR family.
...
Onto Microchip’s most-loved child, the PIC. The new PIC16F18446 is another overachiever when it comes to peripherals.
...
Finally, there’s the new PICkit 4 programmer/debugger ($48). Let’s hope it rights some of the wrongs perpetrated by the deposed PICkit 3. Especially, in my case, the inability to function at the 3V of my project! On the plus side, brownie points to any company that offers multi-platform support (it works under MacOS, Linux, and even Windows).
This Xplained Pro board features the newly released ATmega4809 microcontroller. This device is packed with features such as Core Independent Peripherals, Event System, Intelligent Analog and Low Power. Programming the Xplained Pro board is easy and fast with Atmel Studio and Atmel Start. In this video we are demonstrating how you can get up and running with the Xplained Pro board with a Blink application in minutes.
Those heading to Maker Faire this weekend are invited to attend Massimo Banzi’s semi-annual ‘State of Arduino’ talk, where you can learn more about our latest developments including the MKR Vidor 4000, Uno WiFi Rev2, and our Arduino Day releases.
Both the MKR Vidor 4000 and Uno WiFi Rev2 will be available on the Arduino online store at the end of June.
Hmm, that says "It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. "
- but the image shows a crystal on the Mega23U, and what looks like just 32KHz support (EPSON?) on 4809 ? Or has the 4809 secretly added Crystal Oscillator back into the mix ?
Or is this just lazy copy/paste ?
Other designs have allowed a CLK out from the Debug chip, to feed the MCU, but I don't think they did that here ?
I thought they resist to add Xmega to Arduino in order to be consistent on using the Mega328. Now I see they skip Xmega. Why ? What's wrong with Xmega ?

Nice, I'm happy that someone is using my programmer software on a product. From my github traffic, I can add that this board can be purchased here: https://www.tindie.com/products/...
And the fact that in this board an atmega88 is used to host the firmware made me notice that I can easily reduce the size of an array (I left a huge safety margin) and make it fit in an atmega48. That would save a few cents to the designer, not that it really matters in this case.
Product Change Notification - GBNG-06LXXH156 - 25 Jun 2018 - CCB 2856 Final Notice: Qualification of Microchip Fabrication site (FAB 4) for selected Atmel products manufactured with the 59.91K process technology.
Have you ever wanted to periodically sample an ADC without using code? Have you ever wanted to trigger sensor readings without using CPU resources to do so? The Event System is a feature on some newer AVR® devices that allows autonomous communication between peripherals. This means that you can now trigger sensors, timers, and readings without needing CPU intervention. In this tutorial we will not only cover how to set up the Event System on an AVR device; but we will also cover how to utilize this feature to take more workload off of your CPU.
The AVR-IoT WG Development Board gives developers the ability to add Google Cloud connectivity to new and existing projects with a single click using a free online portal at www.AVR-IoT.com.
...
Powerful AVR microcontroller (MCU) with integrated peripherals: The ATmega4808 8-bit MCU brings the processing power and simplicity of the AVR architecture with added advanced sensing and robust actuation features. With the latest Core Independent Peripherals (CIPs) that decrease power consumption, it provides cutting-edge performance in real-time sensing and control applications.

TopWell, there are differences, I doubt they justify $30 though. I'll compare the tiny817, which has both versions:
Tiny 817 Mini:
Tiny 817 Pro:
So the pro has a few more features, uses the EDBG debugger instead of the mEDBG which is kinda slow.

TopThe Pros are usually bigger boards (and bigger processors), and come populated with the XPro headers - so that you can plug on XPro expansion boards.
As the name (and price) suggests, the Minis are smaller and don't have the extras.

Yes, this note appears in the Xmega timer manual (AVR1306):
...Note that on the XMEGA, the byte order for multi-byte access is always from the least significant byte to the most significant byte.
So does the megaAVR 0-series follow along with Xmega, or use the classic mega avr sequence?
They had the datasheet for the mega328PB reversed (following xmega) & finally corrected it:
