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 AMGTM EPROM 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  
Y
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.  
Y
Fast turn-off for microprocessor compatibility  
Y
Manufacturers identification code  
Y
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.
