General Description
The NM27C512 is a high performance 512K UV Erasable Electrically Programmable Read Only Memory (EPROM). It is manufactured using Fairchild’s proprietary CMOS AMG™ EPROM technology for an excellent combination of speed and economy while providing excellent reliability.
The NM27C512 provides microprocessor-based systems storage capacity for portions of operating system and application 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. Frequently-used software routines are quickly executed from EPROM storage, greatly enhancing system utility.
