NMC27C64
65,536-Bit (8192 x 8) CMOS EPROM
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.
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.

(Note 6) (Note 9)
Note 1: Stresses above those listed under
"
Absolute Maximum Ratings
"
may cause permanent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Note 2: This parameter is only sampled and is not 100% tested.
Note 3: OE may be delayed up to t
ACC
- t
OE
after the falling edge of CE without impacting t
ACC
.
Note 4: The t
DF
and t
CF
compare level is determined as follows:
High to TRI-STATE
, the measured V
OH1
(DC)
0.10V;
Low to TRI-STATE, the measured V
OL1
(DC) + 0.10V.
Note 5: TRI-STATE may be attained using OE or CE .
Note 6: The power switching characteristics of EPROMs require careful device decoupling. It is recommended that at least a 0.1 F ceramic capacitor be used on every device
between V
CC
and GND.
Note 7: The outputs must be restricted to V
CC
+ 1.0V to avoid latch-up and device damage.
Note 8: 1 TTL Gate: I
OL
= 1.6 mA, I
OH
= -400 A.

Note 9: V

may be connected to V

except during programming.
Note 10: Inputs and outputs can undershoot to -2.0V for 20 ns Max.
