Features, Applications

The 64K UV erasable, electrically reprogrammable and one-time programmable (OTP) CMOS EPROM ideally suited for applications where fast turnaround, pattern experimentation and low power consumption are important requirements. 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 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. A new pattern can then be written electrically into the device by following the programming procedure. The NMC27C64N is packaged a 28-pin dual-in-line plastic molded package without a transparent lid. This part is ideally suited for high volume production applications where cost is an important factor and programming only needs to be done once. This family of EPROMs are fabricated with Fairchild's proprietary, time proven CMOS double-poly silicon gate technology which combines high performance and high density with low power consumption and excellent reliability.
