So pic42 will be armed :)
After the pic32mx/mz experience they rather acquire new arch off the shelf :)
arduinoUno with pic328p :)

Or they buy a rival, strip the assets, and close them down... Just like Microsoft did with Nokia ;)

Bad news for you - another forum to care about - Arduino.
For example:
how to burn the bootloader into pic328p?
:D

.. Atmel's board will consider in good faith any changes to the Dialog merger agreement or other arrangements that Dialog may offer in writing and would be legally binding upon Dialog by 5:00 PM California time on Tuesday, January 19, 2016.

Microchip's offer will remain open and binding until 10:00 PM California time on Tuesday, January 19, 2016. If Atmel terminates the Dialog merger agreement, it will be required to pay a termination fee in the amount of $137,300,000 to Dialog.

There can be no assurance that Atmel will terminate the Dialog merger agreement or enter into the Microchip merger agreement.

NYTimes
Code:
Microchip Technology agreed to acquire a fellow chipmaker, the Atmel Corporation, for about $3.6 billion, part of a wave of mergers and acquisitions within the semiconductor industry.
Chip makers have been combining to cut costs and build scale for their customers.

Maybe a new trigger for considering arm for retrobsd :)

$3.6 billion is Microchip's income for 9 years.

They are in most home routers, and that's a huge number of routers...

Routers - mips, but not from Microchip, I guess. And those are not mcus but big cpus with external dram.
Would be interesting to see how the guys are going to shuffle with their product portfolios.

Still MIPS, whether it's a CPU, a SoC (which is what most routers are, not CPUs) or an MCU. They license the core, like ARM do, so it's not about what else is on the die with the core, but how many dies have the core. I think what you are actually asking is what percentage of MIPS licensees use the core in MCUs and what percentage of the MCU market those licensees have, coupled with what percentage of the MCUs that licensee produces use the MIPS core they license.

But then you have to define just what an MCU is. The PIC32MZ...DA - since that can have a big chunk of DDR2 attached to it, is that still an MCU or is it a SoC now? What's the dividing line between them? Where do MCUs end and SoCs begin? We call the Boredcum chip on the Pi a SoC, but what makes that different to the PIC32MZ...DA MCU? Could a PIC32MX795 with your RAMDisk be categorized as a SoC if it's running RetroBSD?

Serge, do MIPS actually produce any chips of their own these days (for public consumption)? I know that back in the day they used to manufacture CPUs (DEC used them in the DECstations that I used to use when younger) but do they actually make them these days, or is it all about licensing to other manufacturers?

I would say an MCU is a single chip/die solution where cpu+ram+rom+i/o - the basic necessary components for providing a performance of such a MCU solution - all reside on the single chip.

An external dram/sram/flash or whatever else could be connectable to an MCU, but such external components are not necessary for providing the most typical MCU functionality, and/or, the external component's operation does not represent its native functionality.

Ie. pic32mz is an mcu, pic32mzda is also an mcu as it cannot execute out of the external dram.
Atmega1284p is an mcu even Jaromir is running Linux on it (because the 32MB dram is bitbanged)..
STM32F4xx is an mcu even you can connect a dram/sram to it, and execute out of it, but you do not need those for providing a typical functionality of an mcu.

Or, to make it simple - what looks like an mcu, walks like an mcu, talks as an mcu, is diy solderable as an mcu, easy programmable as an mcu, it smells like an mcu - IS AN MCU!

Yes it can.

"Technically possible to execute out of dram" is not native to it.. That smells like a WA.

I don't understand what you mean there. It's perfectly possible, it's just that isn't it's prime intention. It's designed as a framebuffer. But you can execute direct from it. What is "native"?

When the intended purpose is the frame buffer, running a program out of it is not its native purpose.. I would be extremely happy to see in the datasheet (you cannot publish) a wording saying "the external dram could be used as the main operational memory without limitation if required" or something like that..
