DESCRIPTION

The M27W101 is a low voltage 1 Mbit EPROM of-

fered in two range UV (ultra violet erase) and OTP

(one timeprogrammable). It is ideally suited for mi-

croprocessor systems requiring large data or pro-

gram storage and is organized as 131,072 by 8

bits.

The M27W101 operates in the read mode with a

supply voltage as low as 2.7V at –40 to 85 °C tem-

perature range.

A0-A16

Q0-Q7

The decrease in operating power allows either a

reduction of the size of the battery or an increase

in the time between battery recharges.

M27W101

The FDIP32W (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.

For application where the content is programmed

only one time and erasure is not required, the

M27W101 is offered in PDIP32, PLCC32 and

TSOP32 (8 x 20 mm) packages.
