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 micro-
processor systems requiring large programs and is
organised as 262,144 words of 16 bits.
The FDIP40W (window ceramic frit-seal package)
and the JLCC44W (J-lead chip carrier packages)
have transparent lids which allow the user to ex-
pose 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.
