The M27C512 is a 512 Kbit UV (ultra violet erase) EPROM. It is ideally suited for applications where fast turn-around and pattern experimentation are important requirements and is organized as 65536 by 8 bits. The FDIP28W (window ceramic frit-seal package) has 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 to the device by following the programming procedure.
