General Description
The NMC27C64 is a 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.
