While most PIC32 should be well capable of the task, the downside is that few people have experience with them and it will be much harder to get help. You're a lot more on your own with a PIC32. You definitely need to read the data sheet, carefully, several times (not that wouldn't have to with a PIC 18, but now you really really need to do your own homework). > http://futurlec.com/SMD_Adapters.shtml (last item at the bottom of > the page).

I still don't understand why you need a package with so many pins. Have you figured out how many pins you really need for each function? Wouldn't a 40 pin PIC do it? Being able to make do with a 40 pin PIC is desirable because that's the largest size that comes in DIP package. For one off hobby use, it may actually be better to use external multiplexers so that a 40 pin DIP package can be used than to mess with a .4mm pitch SMD package. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
