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 National’s latest CMOS
split gate EPROM technology which enables it to operate at
speeds as fast as 120 ns access time over the full operating
range.
The NM27C256 provides microprocessor-based systems
extensive storage capacity for large portions of operating
system and application software. Its 120 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 pin-
out which provides an easy upgrade path for systems which
are currently using standard EPROMs.
The NM27C256 is one member of a high density EPROM
Family which range in densities up to 4 Mb.
