NM27C256

262,144-Bit (32K x 8) High Performance CMOS EPROM

The NM27C256 is one member of a high density EPROM Family

which range in densities up to 4 Mb.

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.

Features

■ High performance CMOS

—90 ns access time

The NM27C256 provides microprocessor-based systems exten-

■ JEDEC standard pin configuration

sive storage capacity for large portions of operating system and

— 28-pin PDIP package

application software. Its 90 ns access time provides high speed

— 32-pin chip carrier

operation with high-performance CPUs. The NM27C256 offers a

— 28-pin CERDIP package

single chip solution for the code storage requirements of 100%

■ Drop-in replacement for 27C256 or 27256

firmware-based equipment. Frequently-used software routines

are quickly executed from EPROM storage, greatly enhancing

system utility.

■ Manufacturer’s identification code

The NM27C256 is configured in the standard EPROM pinout

which provides an easy upgrade path for systems which are

currently using standard EPROMs.
