DESCRIPTION

The M27C322 is a 32 Mbit EPROM offered in the

UV range (ultra violet erase). It is ideally suited for

microprocessor systems requiring large data or

program storage. It is organised as 2 MWords of

16 bit. The pin-out is compatible with a 32 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.

A0-A20

Q0-Q15

For applications where the content is programmed

only one time and erasure is not required, the

M27C322 is offered in PDIP42 package.
