1 / 10 page 1 www.fairchildsemi.com www.fairchildsemi.com FM27C256 FM27C256 262,144-Bit (32K x 8) High Performance CMOS EPROM General Description The FM27C256 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 FM27C256 provides microprocessor-based systems exten- sive 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 FM27C256 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. The FM27C256 is configured in the standard EPROM pinout which provides an easy upgrade path for systems which are currently using standard EPROMs. Block Diagram January 2000 The FM27C256 is one member of a high density EPROM Family which range in densities up to 4 Mb.
