P DESCRIPTION
te The M27V402 is a low voltage, low power 4 Mbit
le UV erasable and electrically programmable
EPROM, ideally suited for handheld and portable
so microprocessor systems requiring large programs.
b It is organized as 262,144 by 16 bits.
O 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
t(s of the battery or an increase in the time between
battery recharges.
c The FDIP40W (window ceramic frit-seal package)
u has a transparent lid which allows the user to ex-
rod pose the chip to ultraviolet light to erase the bit pat-
tern. A new pattern can then be written to the
P device by following the programming procedure.
te For applications where the content is programmed
only one time and erasure is not required, the
le M27V256 is offered in PDIP40, PLCC44 and
Obso TSOP40 (10 x 20 mm) packages.
