This is a FFFAQ
16f84 (68 file registers == ram bytes) is upwards compatible with 16c84
(36), except for:
- polarity of power-on timer enable bit
- code-protection bits
Neither will be very important for a hobby project.
Using the appropriate header files (in whathever language you use) will
useually take care
of these differences, but in a pinch you can simply substitute a 16f84 for
a 16c84,
invert the power-on enable (if you care at all) and live with a
less-than-perfect
code protection (if you enabled this at all).

Wouter.
