NM27C256N200 Datasheet PDF - Fairchild

●General Description

●The NM27C256 is a 256K Electrically Programmable Read Only Memory. It is manufactured in Fairchild’s latest CMOS split gate EPROM technology which enables it to operate at speeds as fast

●as 90 ns access time over the full operating range. The NM27C256 provides microprocessor-based systems extensive storage capacity for large portions of operating system and application software. Its 90 ns access time provides high speed operation with high-performance CPUs. The NM27C256 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.
