NM27C040
4,194,304-Bit (512K x 8) High Performance
CMOS EPROM
General Description
The NM27C040 is a high performance, 4,194,304-bit Electrically
Programmable UV Erasable Read Only Memory. It is organized
as 512K words of 8 bits each. Its pin-compatibility with byte-wide
JEDEC EPROMs enables upgrades through 8 Mbit EPROMs.
The “Don’t Care” feature on V
during read operations allows
memory expansions from 1M to 8 Mbits with no printed circuit
board changes.
The NM27C040 provides microprocessor-based systems exten-
sive storage capacity for large portions of operating system and
application software. Its 120ns access time provides high speed
operation with high-performance CPUs. The NM27C040 offers a
single chip solution for the code storage requirements of 100%
firmware-based equipment. Frequently used software routines
are quickly executed from EPROM storage, greatly enhancing
system utility.
The NM27C040 is manufactured using Fairchild’s advanced
CMOS AMG EPROM technology.
