Hi there, first excuseme for my english...

Time ago I have had a question about microcontrollers with flash memory
and rom memory. Which are the difference between them?, apart of the
feature of flash memory to be reprogramed, there is any difference in
cost or any else fact?, which are the advantage of ROM
microcontrollers?, for examle the PIC18F252 and PIC18C252. For desing
stuff is clear that FLASH micros are better, but in production?, which
are better?

Thanks!

Depends on quantities. For small quantities Flash is best but is you get to
a million parts a year then masked ROM will be cheaper.
