I ASSUME A 16F877A-04 is a 4 meg chip?
Well, what is a 16F877A-I/P operating speed??
I have RTFM , but obviouslt not every page, 'cos I can't see it anywhere?


Thanks as always.

It's a bit "muddy" as a subject. :)
I think they've changed their numbering conventions as time went along.

For a guide to all Microchip suffix' there is a table in this extremely HUGE file.

While the -04 does specify DC-4Mhz ....
The -I/P means it's (I) "Industrial Temperature range" in a (P) "Plastic DIP" package. Frequency is not specified in the part number. In which case the datasheet takes precedence.

And the datasheet for a 16F877A shows that it's DC-20Mhz

Clear as ... well, you know.
