NM27C512

524,288-Bit (64K x 8) High Performance CMOS EPROM

General Description

The NM27C512 is a high performance 512K UV Erasable

Electrically Programmable Read Only Memory (EPROM). It

is manufactured using National’s proprietary 0.8 micron

CMOS AMG^TMEPROM technology for an excellent combi-

nation of speed and economy while providing excellent reli-

ability.

The NM27C512 is one member of a high density EPROM

Family which range in densities up to 4 Megabit.

Features

High performance CMOS

Ð 90 ns access time

The NM27C512 provides microprocessor-based systems

storage capacity for portions of operating system and appli-

cation software. Its 90 ns access time provides no-

wait-state operation with high-performance CPUs. The

NM27C512 offers a single chip solution for the code storage

requirements of 100% firmware-based equipment. Fre-

quently-used software routines are quickly executed from

EPROM storage, greatly enhancing system utility.

Fast turn-off for microprocessor compatibility

Manufacturers identification code

JEDEC standard pin configuration

Ð 28-pin DIP package

Ð 32-pin chip carrier

The NM27C512 is configured in the standard JEDEC

EPROM pinout which provides an easy upgrade path for

systems which are currently using standard EPROMs.
