The NMC27C64 is designed to operate with a single +5V power supply with ±10% tolerance. The CMOS design allows the part to operate over extended and military temperature ranges. The NMC27C64Q is packaged in a 28-pin dual-in-line package with a quartz window. The quartz window allows the user to expose the chip to ultraviolet light to erase the bit pattern.
