M27C1001
Device description
11/24
Byte 0 (A0 = V
IL
) represents the manufacturer code and byte 1 (A0 = V
IH
) the device
identifier code. For the STMicroelectronics M27C1001, these two identifier bytes are given
in
Table 3
and can be read-out on outputs Q7 to Q0.

Erasure operation (applies to UV EPROM)
The erasure characteristics of the M27C1001 is such that erasure begins when the cells are
exposed to light with wavelengths shorter than approximately 4000 . It should be noted
that sunlight and some type of fluorescent lamps have wavelengths in the 3000-4000
range. Research shows that constant exposure to room level fluorescent lighting could
erase a typical M27C1001 in about 3 years, while it would take approximately 1 week to
cause erasure when exposed to direct sunlight. If the M27C1001 is to be exposed to these
types of lighting conditions for extended periods of time, it is suggested that opaque labels
be put over the M27C1001 window to prevent unintentional erasure. The recommended
erasure procedure for the M27C1001 is exposure to short wave ultraviolet light which has a
wavelength of 2537 . The integrated dose (i.e. UV intensity x exposure time) for erasure
should be a minimum of 15 W-sec/cm
2
. The erasure time with this dosage is approximately
15 to 20 minutes using an ultraviolet lamp with 12000 μW/cm
2
power rating. The M27C1001
should be placed within 2.5 cm (1 inch) of the lamp tubes during the erasure. Some lamps
have a filter on their tubes which should be removed before erasure.
