524,288-Bit (64Kx 8) High Performance CMOS EPROM
General Description
The NM27C512isa high performance 512KUV Erasable
Electrically Programmable Read Only Memory (EPROM).It manufactured using National’s proprietary0.8 micron
CMOS AMGTM EPROM technologyforan excellent combi-
nationof speedand economy while providing excellentreli-
ability.
The NM27C512 provides microprocessor-based systems
storage capacityfor portionsof operating systemand appli-
cation software.Its90ns access time provides no-
wait-state operation with high-performance CPUs. The
NM27C512 offers asinglechip solutionforthe code storage
requirementsof 100% firmware-based equipment. Fre-
quently-used software routinesare quickly executed from
EPROM storage, greatly enhancing system utility.
The NM27C512is configuredin the standard JEDEC
EPROM pinout which providesan easy upgrade pathfor
systems whichare currently using standard EPROMs.
The NM27C512is one memberofa high density EPROM
Family which rangein densitiesupto4 Megabit.
