I had been assuming that the newer, high-end 18FXXX PICs were more expens= ive than the mid-range 16F8XX chips, but just noticed in the digikey catalog that they are about the same price. So, what=92s the catch? Is there any disadvantage to using say the 18F45= 2 over the 16F877? Twice the program space appeals to me. The peripherals seem roughly equivalent. --BobG -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
