... C CP Selection Guide Minimum Address Set-up Time Maximum Clock to Output Maximum Operating Current Standard Cypress Semiconductor Corporation Document #: 38-04007 Rev Reprogrammable Registered PROM Functional Description The CY7C245A is a high-performance electrically programmable, read-only memory packaged in a slim 300-mil plastic or hermetic DIP. The ceramic package may be equipped with an erasure window ...

... For this reason, an opaque label should be placed over the window if the PROM is exposed to sunlight or fluorescent lighting for extended periods of time. The recommended dose for erasure is ultraviolet light with a wavelength of 2537 Angstroms for a minimum dose (UV intensity multiplied by exposure time Wsec/cm2. For an ultraviolet lamp with a 12 mW/cm2 power rating the exposure time would be approximately 35 minutes ...
