DESCRIPTION
The M27V402 is a low voltage, low power 4 Mbit
UV
erasable
and
electrically
EPROM, ideally suited for handheld and portable
microprocessor systemsrequiring 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 op-
erating power allows either a reduction of the size
of the battery or an increase in the time between
battery recharges.
The FDIP40W (window ceramic frit-seal package)
has a transparent lid which allows 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.
