HANDLING THE MB89P625/P627
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 Ws/cm
2
is required to completely erase an internal EPROM. This dosage
can be obtained by exposure to an ultraviolet lamp (wavelength of 2537 Angstroms ()) with intensity of 12000
μ
W/cm
2
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 4000. Although erasure time will be much longer than with UV source at 2537, 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.
