> I've sampled some 18F458's from MC, but received the Extended Temperature > version (E/P) instead of the normal Industrial (I/P). You're lucky! Industrial parts have anoying bugs that the latest Extended Temperature devices don't (if I didn't missunderstand the errata sheets). I'm working at 16 MHz and I'm willing to get the E/P parts for developing. The bugs are a nightmare if you program in 'C'. As soon as MC ships to Spain, I will order some of them! Just a comment. I can't answer your main question :) Ovidio Vazquez Jara -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
