DESCRIPTION
The M27V201 is a low voltage 2 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 storage and is organised as 262,144 by 8
bits.
The M27V201 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 a transparent lid which allow the user to ex-
pose the chipto ultraviolet light to erase the bit pat-
tern.
