NM27C512
524288-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 08 micron
CMOS AMGTM EPROM technology for an excellent combi-
nation of speed and economy while providing excellent reli-
ability
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
The NM27C512 is configured in the standard JEDEC
EPROM pinout which provides an easy upgrade path for
systems which are currently using standard EPROMs
The NM27C512 is one member of a high density EPROM
Family which range in densities up to 4 Megabit
