M27C322-100F1

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 expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written rapidly to
the device by following the programming procedure.
For applications where the content is programmed
only one time and erasure is not required, the
M27C322 is offered in PDIP42 package.
