Ha! Forgot that I'd already bought the DM320010 (which has the PIC32MZ2064DAG169 device) so I could see if my project could run with less memory.
 
Just run up the coffee maker demo and the chip can now be touched! Yes, a little warm, but MUCH cooler. Result!
 
You have almost certainly hit the nail on the head with the external DDR interface being the culprit. I will scratch my chin pensively and make sure 32Mbyte of RAM will be enough, and I think I'm then a happy bunny.

Hi,
thank you for that information. I would estimate the PIC32MZ2064DAG169 is getting hotter, because more parts on die producing heat.
But when it is working cooler, it is interesting.
 
Perhaps other external flash could help..

FYI the MZ2064DAG169 runs with a case temperature of 44C/110F - so still fairly warm but much better than the 60C of the MZ2064DAA288.
