DESCRIPTION
The M27V801 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 microprocessorsystems requiringlarge data or
program storageand is organized as 1,048,576by
8 bits.
The M27V801 operates in the read mode with a
supply voltage as low as 3V. The decrease in op-
erating power allows either a reduction of the size
of the battery or an increase in the time between
battery recharges.
The FDIP32W (window ceramic frit-seal package)
has transparent lid which allows the user to ex-
pose the chipto ultraviolet light to erase the bit pat-
tern. A new pattern can then be written to the
device by following the programming procedure.
