Hi. Yes, I could put both data sheet besides of each other, but before I do that, is there any (major) differences between the CAN and non-CAN 18Fxxx parts ? There seems to be a minor difference in available flash and RAM (A little more in some the CAN parts), but apart from that, I havn't seen any major difference. Or to put it in another way, could a CAN part (xx8) be used as the corresponding non-CAN (xx2) part without anything "missing" or other problems ? Like having to specificaly disable the CAN module.
