Hello Everybody,
I have a EPROM programmer at my college. I wanted to burn code in my DS89C450 uC. the programmer had only DS89C420. i checked the datasheet it says that the 2 IC's are pin compatible and applications using DS89C420 can be replaced with DS89C450. When i tried burning my code the programmer says " MANUFACTURER'S CODE NOT MATCHED". what does it mean and what should i do?
Not too much problems with chips that lets out the magic smoke from incorrect programming parameters.
The big problem is chips that just got a little bit damaged, or chips that was "almost" programmed. I.e. chips that gets sent out to a customer and then fails.
When the chip blows up directly while being programmed, it's just a fixed learning cost, not to program with wrong algorithms. the pro will agree with you, the amateur not
