NM27C240
4,194,304-Bit (256k x 16) High Performance
CMOS EPROM
General Description
The NM27C240 is a high performance Electrically Programmable
UV erasable ROM (EPROM). It contains 4,194,304 bits config-
ured as 256k x 16 bits. It is offered in both erasable versions for
prototyping and early production applications as well as non-
erasable, plastic packaged versions that are ideal for high volume
and automated assembly applications.
The NM27C240 operates from a single 5V
±
10% supply in the
read mode.
The NM27C240 is offered in both DIP and surface mount pack-
ages. The DIP package is a 40-pin dual-in-line ceramic with a
quartz window to allow erasing. The surface mount package is a
44-pin PLCC that is offered in OTP.
This EPROM is manufactured using Fairchild’s proprietary AMG
EPROM technology for an excellent combination of speed and
economy while providing excellent reliability.
