8755A Proramming Module
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
2537
A.
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 12,000p
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.
