NMC27C64Q DIP IC

General Description
TheNMC27C64 isa 64KUVerasable,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 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. A new
pattern can then be written electrically into the device by following
the programming procedure.
The NMC27C64N is packaged in 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.
