NMC27C64

65,536-Bit (8192 x 8) CMOS EPROM

suited for high volume production applications where cost is an

important factor and programming only needs to be done once.

General Description

TheNMC27C64isa64KUVerasable,electricallyreprogrammable

and one-time programmable (OTP) CMOS EPROM ideallysuited

for applications where fast turnaround, pattern experimentation

and low power consumption are important requirements.

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.

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.

Features

High performance CMOS

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.

—150 ns access time

JEDEC standard pin configuration

—28-pin Plastic DIP package

—28-pin CERDIP package

Drop-in replacement for 27C64 or 2764
