The reson should be one of followings:
1.The chip is a blank chip.
2.The chip's lock bits been set.
3.The jumper/DIP setting on the programmer are incorrect. You should be able to get correct ID if the jumper and the DIP setting are correct. |

DIP setting: 2,3,5,6,8,10,12 ON and 1,4,7,9,11 OFF. Using default jumper setting. Try ID the chip. If you can get correct ID, then your setting should be OK.
There are no way to unlock it. Unless erase it, but the data in chip will be erased too.
But, always, there are people having their ways to unlock it. See http://www.break-ic.com |
