NM27C512

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

The NM27C512 is one member of a high density EPROM Family

which range in densities up to 4 Megabit.

General Description

The NM27C512 is a high performance 512K UV Erasable Electri-

cally Programmable Read Only Memory (EPROM). It is manufac-

tured using Fairchild’s proprietary CMOS AMG™ EPROM tech-

nology for an excellent combination of speed and economy while

providing excellent reliability.

Features

■ High performance CMOS

— 90 ns access time

■ Fast turn-off for microprocessor compatibility

TheNM27C512providesmicroprocessor-basedsystemsstorage

capacity for portions of operating system and application soft-

■ Manufacturers identification code

ware. 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. Frequently-used software routines are quickly

executed from EPROM storage, greatly enhancing system utility.

■ JEDEC standard pin configuration

— 28-pin PDIP package

— 32-pin chip carrier

— 28-pin CERDIP package

The NM27C512 is configured in the standard JEDEC EPROM
