DESCRIPTION

The M27W102 is a low voltage 1 Mbit EPROM

offeredin thetworangesUV (ultravioleterase)and

OTP (one time programmable). It is ideally suited

for microprocessorsystems requiring large data or

programstorageand is organizedas65,536words

by 16 bits.

Figure 1. Logic Diagram

The M27V102 operates in the read mode with a

supply voltage as low as 3V. 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 FDIP40W (window ceramic frit-seal package)

has a transparent lid which allows the user to

expose the chip to ultraviolet light to erase the bit

pattern. A new pattern can then be written to the

device by following the programming procedure.
