DESCRIPTION
The M27W402 is a low voltage 4 Mbit EPROM of-
fered in the two range 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
16 bits.
The M27W402 operates in the read mode with a
supply voltageas low as 2.7V at –40 to 85
°
C tem-
perature range. The decrease in operating power
allows either a reduction of the size of the battery
or an increase in the time between battery re-
charges.
The FDIP40W (window ceramic frit-seal package)
has a transparent lids which allow 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.
For applications wherethe content is programmed
only one time and erasure is not required, the
M27W402 is offered in PDIP40, PLCC44 and
TSOP40 (10 x 20 mm) packages.
