M27C4001

Summary 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) has a transparent lid which allows 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 20 mm) packages.

In order to meet environmental requirements, ST offers the M27C4001 in ECOPACK®

packages.

ECOPACK packages are Lead-free. The category of second Level Interconnect is marked

on the package and on the inner box label, in compliance with JEDEC Standard JESD97.

The maximum ratings related to soldering conditions are also marked on the inner box label.

ECOPACK is an ST trademark. ECOPACK specifications are available at:
