Summary description
The M27C4002 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 organized as 262,144 words of 16 bits.
The FDIP40W (window ceramic frit-seal package) has transparent lids which allow 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 M27C4002 is offered in PDIP40, PLCC44 and TSOP40 (10 x 20 mm)
packages.
In order to meet environmental requirements, ST offers the M27C4002 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.
