    Question Replacing pic16f627a from a 16f84(a)

    Just out of curiosity, can I use the 627a instead of the 84(a) and keep the programming the same? I am using picBasic pro compiler. Secondly, if I don't use xtal, does the 627a automatically uses it's intrc if i make this selection on epicwin....if not what is the code to tell the 627a to use intrc for both picBasic and picBasic Pro.

    Thank you

    Yes, but 627A, 628A, 648A (all use same data sheet ) has Comparators, whereas the F84 does not. So add CMCON = 7 to disable them. Please look at this thread: http://www.picbasic.co.uk/forum/showthread.php?t=561,
    Now as far as using Internal Osc, read this thread:
