Summary description

The M27C1001 is a 1 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 organized as 131,072 words of 8 bits.

The FDIP32W (window ceramic frit-seal package) has a transparent lid that enables 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 M27C1001 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20 mm) packages.

In order to meet environmental requirements, ST offers the M27C1001 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: www.st.com.
