DESCRIPTION

The M27V322 is a 32 Mbit EPROM offered in the

UV range (ultra violet erase) and OTP range. It is

ideally suited for microprocessor systems requir-

ing 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.

For applications where the content is programmed

only one time and erasure is not required, the

M27V322 is offered in PDIP42 package.
