PIC16C84 and PIC16F84

[dan williams]

F means flash, as in you can reprogram it, the C is EPROM or OTP (one
time programmable) I dont remember, the book is out of reach of my
arm...

aside from that there identicle.

any other 16x84 questions just ask...

There's no difference at all between 16F84 and 16C84. The 16C84 is an
obsolete device that was replaced by 16F84. I have some 16C84 left and they
work properly even when using the 16F84/16F84A header in the asm file. Both
16F84 and 16C84 are flash MCUs. The 16CR84 is the ROM version of the same
device.
The datasheet you can download from microchip web site.
Hope this was helpful

Whoah... C84 has 36 bytes of RAM, F84 has 68, PWRTE config bit sense is
reversed, /MCLR has a filter in the F84, not in the C84, and some
electrical characteristics (and probably programming characteristics,
whatever the consequences of "Flash" vs. "EEPROM" are) are different.

These days you should consider using the F628 rather than either of those
two old dogs.

What if you have several of the "old dogs" in the junk box?
What if you don't use that many variables at once?
What if you can go around these small differences for small experimenting
and learning purpose?
My mistake about the two devices being identical, they are strictly not.
Although very close. If you don't expect too much from them, then is ok to
use them interchangeably.
Anyway I liked the "whoah effect", and indeed using the F628 is a good
alternative if you don't have any MCU at all. The 16F628 is half the price
of the 16F84A at Farnell.
