The M27C16 is a 16,384 bit UV erasable and electrically programmable memory EPROM, ideally suited for applications where fast turn-around and pattern experimentation are important requirements. The M27C16 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.
