DESCRIPTION
The M2732A is a 32,768 bit UV erasable and
electrically programmable memory EPROM. It is
organized as 4,096 words by 8 bits. The M2732A
with its single 5V power supply and with an access
time of 200 ns, is ideal suited for applications where
fast turn around and pattern experimentation one
important requirements.
The M2732A is honsed in a 24 pin Window Ceramic
Frit-Seal Dual-in-Line package. The transparent lid
allows the user to expose the chip to ultraviolet light
to erase the bit pattern. A new pattern can be then
written to the clerice by following the programming
procedure.
