Hi, I now from start, it's very small chance to find a solution, but I will try. I have a problem with a dental curing Heraeus Kulzer Unixs device. Same years ago I repair this device. The device had blow up same components ( BUZ357, BYT12, ICL7667CPA ). I replace this components and the device was ok. Now I have a really big problem. All components I've changed are now blow up but now also the PIC16C71-04/P it's blow up. The PIC16C71-04/P have a label on it 168XS3-0437. The chance for me, is someone try to read the code from a good one, and he have luck to be with no code protection. Regards, Ciprian

Probability for this chance will be literally zero. Manufacturers (have to) put lots of effort in protecting their desings against copying ... And if getting (some level of) protection is so simple like just setting the copy protection fuse, guess what manufacurers will do ... I guess, your only chance will be to get the µC as an original spare part from the manufacturer. good luck!
I have a problem with a dental curing Heraeus Kulzer Unixs device. The device had blow up same components ,but unfortunately the numbers of ICs are deleted can anybody tell me the numbers of ICs. the 3 optocoupler CNY75GA ,CD4098, I need the number for other 16 pin ic 14 pin and the two with 8 pin ic (the one of 8pin is ICL7667CPA I know it for this forum) Please if anybody know the above ICs number email me or write here in this forum Thank you in advance
