  1. Hello,
    Can somebody tell me who can read rome PIC protected?
    I pay good money for that.
    Please, post me in
     
  2. The whole point of write protecting them is that you can't recover the
    ROM contents. Well, you can always strip off the plastic and image
    the bits, but that's a whole lot more expensive than writing your own
    code...

    Won't work on most PICs, which use EPROM, EEPROM, or Flash memory
    cells. There's no optically visible difference between cells storing
    a 0 vs. a 1.
     
  4. Not by looking at them, but you can optically or eddy current probe them:

  5. 'Imaging', does not imply visual.
    You can get the data with a SEM, but the cost is typically perhaps
    $20000+. You also then have to work out where each 'bit' resides in the
    physical memory structure.

    Best Wishes
