NM27C256
262,144-Bit (32K x 8) High Performance CMOS EPROM
General Description
The NM27C256 is a 256K Electrically Programmable Read Only
Memory. It is manufactured in Fairchild’s latest CMOS split gate
EPROM technology which enables it to operate at speeds as fast
as 90 ns access time over the full operating range.
The NM27C256 provides microprocessor-based systems exten-
sive storage capacity for large portions of operating system and
application software. Its 90 ns access time provides high speed
operation with high-performance CPUs. The NM27C256 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 NM27C256 is configured in the standard EPROM pinout
which provides an easy upgrade path for systems which are
currently using standard EPROMs.
