4 / 9 page PY291A Page 4 of 9 Document # EPROM101 REV OR DEVICE ERASURE If the device is subjected to wavelengths of light below 4000 Angstroms, device erasure will commence. It is therefore recommended to use an opaque label over the window in the event the device will be exposed to lighting for a long time. The UV dose for erasure requires a wavelength of 2,537 Angstroms for a minimum dose of 25 Wsec/cm2. If using a UV lamp of 12 mW/cm2, the exposure time is estimated to be 35 minutes. Devices should be positioned within 1 inch of the lamp during the erasure process. Permanent damage can occur to the devices if exposed to UV light for an extended period of time.
