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. NM27C256 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 pinout which provides an easy upgrade path for systems which are currently using standard EPROMs.
