Description
The M27C801 is an 8 Mbit EPROM offered in the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited for applications where fast turn-around
and pattern experimentation are important requirements and is organized as 1,048,576 by 8
bits.
The FDIP32W (window ceramic frit-seal package) has 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 M27C801 is offered in PDIP32 and PLCC32 packages.
In order to meet environmental requirements, ST offers the M27C801 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.
