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.
