Erase Eeprom Sunlight at Callum Balmain blog

Erase Eeprom Sunlight. To erase the eprom requires external uv light of 400nm or shorter wavelength to ionize the oxide allowing the stored charge to dissipate, reverting the cell to an unprogrammed state. To erase a eprom by sunlight takes long time. Instead of increasing uv exposure unnecessarily, which damages them, it's better to verify erase margin explicitly by doing a low. As an aside, others have looked into this, which i had not seen until now: There is a easy way to do it, break. If it was not direct light, uv doesn't reflect well, so, at most, you'll see 30% of the. I do recall testing them after letting some of them sit in the sun all afternoon. Eeprom chips take hours in direct sunlight. Takes longer if you have vapor (humidity) in the air, or low above the see level, like florida. Some brands of eproms cannot be erased by sunlight.
