EM2

On the EM2 Board:

the Intel® 8755A EPROM can be programmed using any o/the modules listed in Table 1.

The 8755A EPROM is erased when exposed to light with wavelengths shorter than approximately 4000 Ang- stroms (A). Sunlight and certain fluorescent lamps have wavelengths in the 3000A to 4000A range. If the 8755A is to be exposed to sunlight or room fluorescent lighting

for extended periods, then opaque labels should be placed over the window to prevent unintentional erasure.

The recommended erasure procedure is exposure to ultraviolet light which has a wavelength of 2537A. The integrated dose (UV intensity multiplied by exposure time) for erasure should be a minimum of 15W-sec/cm.

The erasure time with this dosage is approximately 15 to 20 minutes using an ultraviolet lamp with a 12,000" W/em 2 power rating. Place the 8755A within one inch of the lamp during erasure. Some lamps include a filter which should be removed before erasure.
