if blankcheck failed, then the erase is fail.
If the chip is locked, then you need to unloack the chip before write it. |

Hi guys, I'm new here.
Bumping on this old thread as I'm having a similar issue
Trying to program a MX29LV160TM with TOP 3100.
The program seems to be writing upon verifying the chip is still blank.
Understand from above that the eeprom could be locked/protected. Is there a way to unlock the chip from topwin7?
Thanks,
Jerome |

| Try on new chips. Brand new chip never in a locked state. |

Thanks for the information about new chip.
I have tried a bunch of new chips but still having the same issue.
Even tried 2 different SOP44/DIP40 adapters.
The chip is recognized properly but the data programmed passes thru.
I've been using this programmer to burn regular Eprom mainly with no problem. I |

Managed to program successfully a MX29F800TMC-90 with TOP3100.
The programmer might just not be compatible with MX29LV160TM. |
