age may result if the EPROM is exposed to high-intensity UV  
light for an extended period of time. 7258 Wsec/cm is the  
Erasure Characteristics  
2
The recommended dose of ultraviolet light for erasure is a  
wavelength of 2537 Angstroms for a minimum dose (UV inten-  
sity multiplied by exposure time) of 25 Wsec/cm2. For an ul-  
traviolet lamp with a 12 mW/cm power rating the exposure  
time would be approximately 35 minutes. The 7C276 needs to  
be within 1 inch of the lamp during erasure. Permanent dam-  
recommended maximum dosage.  
Wavelengths of light less than 4000 Angstroms begin to erase  
the 7C276 in the windowed package. For this reason, an  
opaque label should be placed over the window if the EPROM  
is exposed to sunlight or fluorescent lighting for extended pe-  
riods of time.
