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 microprocessor systems requiring large data or

program storage and is organised as 262,144 by

16 bits.

The M27W402 operates in the read mode with a

supply voltage as low as 2.7V at 鈥?0 to 85擄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 chip to 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 where the 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.
