NMC27C32B
32,768-Bit (4096 x 8) CMOS EPROM
General Description
The NMC27C32B is a 32k UV erasable and electrically re-
programmable CMOS EPROM, ideally suited for applica-
tions where fast turnaround, pattern experimentation and
low power consumption are important requirements.
The NMC27C32B is designed to operate with a single
a
5V
power supply with
g
10% tolerance.
The NMC27C32B is packaged in a 24-pin dual-in-line pack-
age 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.
This EPROM is fabricated with National’s proprietary, time
proven CMOS double-poly silicon gate technology which
combines high performance and high density with low pow-
er consumption and excellent reliability.
