Summary description
Summary description
The M27V160 is a low voltage 16 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 data or program storage. It is organised as either 2 Mbit words of 8 bit or 1
Mbit words of 16 bit. The pin-out is compatible with a 16 Mbit Mask ROM.
The M27V160 operates in the read mode with a supply voltage as low as 3V. The decrease
in operating power allows either a reduction of the size of the battery or an increase in the
time between battery recharges.
The FDIP42W (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 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 M27V160 is offered in PDIP42, SDIP42, PLCC44 and SO44 packages.
In order to meet environmental requirements, ST offers the M27V160 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.
