Fairchild NM27C256V120

32K x 8120 ns0°C ~ 70°C（TA）

Overview

The NM27C256V120 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 NM27C256V120 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 NM27C256V120 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.
