DESCRIPTION
The M27C160 is a 16 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 organised as either 2 Mbit words of
8 bit or 1 Mbit words of 16 bit. The pin-out is com-
patible with a 16 Mbit Mask ROM.
The FDIP42W (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 rapidly to
the device by following the programming proce-
dure.
For applications where the content is programmed
only one time and erasure is not required, the
M27C160 is offered in PDIP42, SDIP42, PLCC44
and SO44 packages.
