DESCRIPTION
The M27V402 is a low voltage, low power 4 Mbit
UV erasable and electrically programmable
EPROM, ideally suited for handheld and portable
microprocessor systems requiring large programs.
It is organized as 262,144 by 16 bits.
The M27V402 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.
