I have tried sticking it under a UV lamp for 30 minutes, but there | seems to be no corruption or any signs that the chip has been erased. The HEX code looks exactly as it was when I programmed | it. Does anyone know how long the chip must stay in UV light? The UV light box I am using, is actually meant for developing | PCB's, but I'm have been told, it has been used to erase EPROMS. | | Regards | Chris Pringle |
