DESCRIPTION

The M27C2001 is a high speed 2 Mbit EPROM of-

fered in the two ranges UV (ultra violet erase) and

OTP (one time programmable). It is ideally suited

for microprocessor systems requiring large pro-

grams and is organised as 262,144 by 8 bits.

The FDIP32W (window ceramic frit-seal package)

and LCCC32W (leadless chip carrier package)

have a transparent lids which allow 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 applications where the content is programmed

only one time and erasure is not required, the

M27C2001 is offered in PDIP32, PLCC32 and

TSOP32 (8 x 20 mm) packages.
