NM27C020
2,097,152-Bit (256K x 8) UV Erasable CMOS EPROM
General Description
The NM27C020 is a high speed 2 Megabit CMOS UV-EPROM
manufactured on Fairchild’s advanced sub-micron technology.
Utilizing the AMG architecture, this advanced CMOS process
delivers high speeds while consuming low power.
The NM27C020 provides microprocessor-based systems exten-
sive storage capacity for large portions of operating systems and
application software. Its 100ns access time provides no-wait-state
operation with high-performance CPUs.
The NM27C020 offers a single chip solution for the code storage
requirements of 100% firmware-based equipment. Frequently-
used software routines are quickly executed from EPROM stor-
age, greatly enhancing system utility.
The NM27C020 is manufactured using Fairchild’s advanced
CMOS AMG EPROM technology, and is one member of a high
density Fairchild EPROM series family which range in densities up
to 4Mb.
