Thanks for all the replies! :) The first of my thinking was could I program it, which is a likely with=20 the Epic programmer, but the OTP, and these are not windowed, which I=20 hadn't picked up on by getting into the data sheet, which was next on=20 the agenda is a NO GO. with only 4 chips, I likely would use those up in=20 fine tuning the programming. I do have a bunch of other chips=20 including 18F84, 16C711/UW (windowed), 18F1320 to choose from. Might try=20 for same pinout as 18F1320 for what few pins I need. If someone in the USA could use these 4 pieces 12C671/P, I'll stick them=20 in a first class mail envelope, send me an address off list. :) Thanks again! :) :) On 2/26/2012 1:42 PM, Carl Denk wrote: > Yes, that's the number on the package 12C671/N.
