1. Recommended Screening Conditions

High-temperature aging is recommended as the pre-assembly screening procedure for a product with a blanked

OTPROM microcomputer program.

2. Programming Yield

All bits cannot be programmed at Fujitsu shipping test to a blanked OTPROM microcomputer, due to its nature.

For this reason, a programming yield of 100% cannot be assured at all times.

3. Erasure

In order to clear all locations of their programmed contents, it is necessary to expose the internal EPROM to an

ultraviolet light source. A dosage of 10 W-seconds/cm2 is required to completely erase an internal EPROM. This

dosage can be obtained by exposure to an ultraviolet lamp (wavelength of 2537 Angstroms (Å)) with intensity

of 12000 µW/cm2 for 15 to 21 minutes. The internal EPROM should be about one inch from the source and all

filters should be removed from the UV light source prior to erasure.

It is important to note that the internal EPROM and similar devices, will erase with light sources having wave-

lengths shorter than 4000Å. Although erasure time will be much longer than with UV source at 2537Å, never-

theless the exposure to fluorescent light and sunlight will eventually erase the internal EPROM, and exposure

to them should be prevented to realize maximum system reliability. If used in such an environment, the package

windows should be covered by an opaque label or substance.
