I have read both datasheet ,but i was a bit confused .Please it is possible to clarify ,that can i use pic16F84a instead of pic 18LF1220 ,i just wanna try something .i have a hex file that must work with 16f84 but it does not ,so i see that someone use instead for same hex 18lf1220 .i do not know if it working or not ,but my question is both IC pin to pin compatible
thanks.
