M27C128-12FI EPROM IC

General Description
The NM27C128 is a high performance 128K UV Erasable Electrically Programmable Read Only Memory. It is manufactured with
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 NM27C128 provides microprocessor-based systems extensive 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 NM27C128 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 NM27C128 is configured in the standard EPROM pinout
which provides an easy upgrade path for systems which are
currently using standard EPROMs

The NM27C128 is one member of a high density EPROM Family
which range in densities up to 4 Mb.
