But my experience is thatr the larger (as in transistor count), the chip,
the more likely it is to fail. And FWIW I've got plenty of (plain) TTL
chips that are gettign on for 40 years old and still working fine. I
suspect there'd be a very raal chance of a flash memory microocntroller
developing bit-rot before then.
You may be right, I don't know, But I _would_ bet that in 40 years time
it'll be a lot easier to find data on TTL chips than tracking down the
person who wrote the firmware for the microcontroller and convinicing him
to give you a copy so you can replace the a dead chip.

than the '74 and
'00 that it would replace on this board).
I'm not sure about that--PICs definitely use less power than
