M27C160 Summary description

5/26

1 Summary description

The M27C160 is a 16-Mbit EPROM offered in two ranges UV (Ultraviolet Erase) and OTP

(One-Time Programmable). It is ideally suited for microprocessor systems requiring large

data or program storage and is organized as either 2 Mbit words of 8 bits or 1 Mbit word of

16 bits. The pin-out is compatible with a 16-Mbit Mask ROM.

The FDIP42W (window ceramic frit-seal package) has a transparent lid which enables the

user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be

written rapidly to the device by following the programming procedure.

For applications where the content is programmed only one time and erasure is not

required, the M27C160 is offered in PDIP42, SDIP42, PLCC44 and SO44 packages.

In order to meet environmental requirements, ST offers the M27C160 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.
