Dave, If the timing is important to you, then hopefully you will get some more feedback from the list. I can only tell what we have experienced. However from what I have learnt from the list, Microchip tends to be quite conservative with their specs, so what I have seen probably does make sense. I believe those new flavours I mentioned will also run up to 10MHz or 20MHz, but I am not 100% certain, as I have not actually seen any in our region yet. There are some people on the list who have actually got their hands on them, but I can not remember who. Up to my *#$& in crocodiles at the moment, so have no time to search for you, sorry. :-( Cheers, Sean -- http://www.piclist.com#nomail Going offline?
