Question

Started by William Oliver December 11, 2005
Hello All,
I have a question. Can someone in the group tell me what is the
differance between a 16F84 and a 16CR84 is. I have looked at the
datasheet but I didn't see anything to tell me the differance between
them.

Thank for the help

William Oliver

16F devices have flash program memory and are reprogrammable. 16C
devices have ROM program memory and are factory programmable. It
seems to me that some 16C devices are user programmable (once) but
the PICStart Pro will not support the 16CR84 which leads me to the
conclusion it is factory programmable only.

Hi,

MPLAB says PROMATE II or ICE 2000. Wow, not even my new PM3!
