FM27C010 1,048,576-Bit (128K x 8) High Performance CMOS EPROM
December 2000

1,048,576-Bit (128K x 8) High Performance
General Description The FM27C010 is one member of a high density EPROM Family
which range in densities up to 4 Megabit.
The FM27C010 is a high performance, 1,048,576-bit Electrically
Programmable UV Erasable Read Only Memory. It is organized Features
as 128K-words of 8 bits each. Its pin-compatibility with byte-wide
JEDEC EPROMs enables upgrades through 8 Mbit EPROMs. I High performance CMOS
The "Don't Care" feature during read operations allows memory -- 90, 120, 150 ns access time
expansions from 1M to 8M bits with no printed circuit board I Fast turn-off for microprocessor compatibility
changes. I Simplified upgrade path
The FM27C010 can directly replace lower density 28-pin EPROMs -- VPP and PGM are "Don't Care" during normal read
by adding an A16 address line and VCC jumper. During the normal operation
read operation PGM and VPP are in a "Don't Care" state which I Manufacturers identification code
allows higher order addresses, such as A17, A18, and A19 to be I Fast programming
connected without affecting the normal read operation. This
I JEDEC standard pin configurations
allows memory upgrades to 8M bits without hardware changes.
-- 32-pin PLCC package
The FM27C010 is also offered in a 32-pin plastic DIP with the
-- 32-pin CERDIP package
same upgrade path.
The FM27C010 provides microprocessor-based systems exten-
sive storage capacity for large portions of operating system and
application software. The FM27C010 offers a single chip solution
for the code storage requirements of 100% firmware-based equip-
ment. Frequently-used software routines are quickly executed
from EPROM storage, greatly enhancing system utility.
The FM27C010 is manufactured using Fairchild's advanced CMOS
AMGTM EPROM technology.
