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.
