As I pointed out in previous post (I was a it hasty sending it before reading all your post) the PIC 24 family have what you need. The smallest ones come as 64 pin TQFP packages, with 0.5mm lead pitch, which are not too bad for hand soldering. Alternatively you could purchase the PIM, which plugs onto a 100 pin square header, but is finer pitch header than 0.1" ... but would be OK for a 1 off, if you are careful about how the leads come out, as it is not 1:1 from the chip. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
