Read Protected PIC

[Marco Torello]

Hello,
Can somebody tell me who can read rome PIC protected?
I pay good money for that.
Please, post me in [email protected]

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.

Not by looking at them, but you can optically or eddy current probe them:

'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.
