DESCRIPTION

The M27C4001 is a 4 Mbit EPROM offered in the

two ranges UV (ultra violet erase) and OTP (one

time programmable). It is ideally suited for microprocessor

systems requiring large programs and

is organised as 524,288 by 8 bits.

The FDIP32W (window ceramic frit-seal package)

and LCCC32W (leadless chip carrier package)

have a transparent lid which allow the user to expose

the chip to ultraviolet light to erase the bit pattern.

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

M27C4001 is offered in PDIP32, PLCC32 and

TSOP32 (8 x 20mm) packages.
