DESCRIPTION
The M27W102 is a low voltage 1 Mbit EPROM
offeredin the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited
for microprocessor systems requiring large data or
program storage and is organized as 65,536 words
by 16 bits.
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.
