DESCRIPTION
The M27W800 is a low voltage 8 Mbit EPROM of-
fered in the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited
for microprocessor systems requiring large data or
program storage. It is organised as either 1 Mbit
words of 8 bit or 512 Kbit words of 16 bit. The pin-
out is compatible with a 8 Mbit Mask ROM.
The M27W800 operates in the read mode with a
supply voltage as low as 2.7V. The decrease in
operating power allows either a reduction of the
size of the battery or an increase in the time be-
tween battery recharges.
The FDIP42W (window ceramic frit-seal package)
has a transparent lid which allows the user to ex-
pose the chip to ultraviolet light to erase the bit pat-
tern. A new pattern can then be written rapidly to
the device by following the programming proce-
dure.
For applications where the content is programmed
only one time and erasure is not required, the
M27W800 is offered in PDIP42 and PLCC44 pack-
age.
