DESCRIPTION

PLCC44 (K)

TSOP40 (N)

10 x 20 mm

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.

Figure 1. Logic Diagram

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 chip to ultraviolet light to erase the bit pat-

tern. A new pattern can then be written to the

device by following the programming procedure.

A0-A17

Q0-Q15

For applications where the content is programmed

only one time and erasure is not required, the

M27V256 is offered in PDIP40, PLCC44 and

TSOP40 (10 x 20 mm) packages.
