DESCRIPTION
The M27C1024 is a 1 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 data or program
storage and is organized as 65,536 words of 16
bits.
The FDIP40W (window ceramic frit-seal package)
has a transparent lid which allows the user to ex-
pose the chip to ultraviolet light to erase the bit pat-
tern. A new pattern can then be written to the
device by following the programming procedure.
For application where the content is programmed
only one time and erasure is not required, the
M27C1024 is offered in PDIP40, PLCC44 and
TSOP40 (10 x 14 mm) packages.
