DESCRIPTION
The M2716 is a 16,384 bit UV erasable and elec-
trically programmable memory EPROM, ideally
suited for applications where fast turn around and
pattern experimentation are important require-
ments.
The M2716 is housed 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 then be
written to the device by following the programming
procedure.
