The M27C160 is a 16 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one-time programmable). It is ideally suited for microprocessor systems requiring large data or program storage and is organized as either 2 Mbit words of 8 bit or 1 Mbit words of 16 bit. The pin-out is compatible with a 16 Mbit Mask ROM. The FDIP42W (window ceramic frit-seal package) has a transparent lid that allows the user to expose the chip to ultraviolet light to erase the bit pattern.
