M27C160
Device description
ambient temperature range that is required when programming the M27C160. To activate
the ES mode, the programming equipment must force 11.5V to 12.5V on address line A9 of
the M27C160, with VPP = VCC = 5V. Two identifier bytes may then be sequenced from the
device outputs by toggling address line A0 from VIL to VIH. All other address lines must be
held at VIL during Electronic Signature mode. Byte 0 (A0 = VIL) represents the manufacturer
code and byte 1 (A0 = VIH) the device identifier code. For the STMicroelectronics M27C160,
these two identifier bytes are given in Table 3 and can be read-out on outputs Q7 to Q0.
Note:
Outputs Q15-Q8 are set to '0'.

Erasure operation (applies to UV EPROM)
The erasure characteristics of the M27C160 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 M27C160 in about 3 years, while it would take approximately 1 week to
cause erasure when exposed to direct sunlight. If the M27C160 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 M27C160 window to prevent unintentional erasure. The recommended
erasure procedure for M27C160 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 30 W-sec/cm2. The erasure time with this dosage is approximately
30 to 40 minutes using an ultraviolet lamp with 12000 W/cm2 power rating. The M27C160
should be placed within 2.5cm (1 inch) of the lamp tubes during the erasure. Some lamps
have a filter on their tubes which should be removed before erasure.
