16F1782 @ 80MHz clock

[CuriousOne]

Can be same approach applied to other chips from 16F series, that support extosc ?
Say 16F1829 ?

I can't say for sure, so try it? There is quite a difference between what I was trying to do (40 Mhz from 32 Mhz. processor) and what you are proposing (80 Mhz. from 32 Mhz. processor).

Nice What is it doing?
I wonder how on-chip EEPROM or program memory writes go.. if supported by the chip.

It's only doing a simple repetitive task - triggered on dig ip by comparators, dig ops driving at any one time one of several hard pull-up transistors in a multiple 1-wire master circuit, with retrigger (blocking) timers. It's basically doing something that could be handled quicker by a few logic gates. The 1-wire communication proper (and everything else) is handled by another on-board µC - of the 18F family.
So the 16F1782 is not writing to EEPROM etc. I'll leave that interesting experiment @80MHz to someone else!

The program's I have written for the 16F1825 running at 40Mhz. (10 mHZ. 4 x PLL) work just fine writing and reading from eeprom. No issues.
