FM27C512 Rev. A
The FM27C512 is a high performance 512K UV Erasable Electri-
cally Programmable Read Only Memory (EPROM). It is manufac-
tured using Fairchild’s proprietary CMOS AMG™ EPROM tech-
nology for an excellent combination of speed and economy while
providing excellent reliability.
The FM27C512 provides microprocessor-based systems storage
capacity for portions of operating system and application soft-
ware. Its 90 ns access time provides no wait-state operation with
high-performance CPUs. The FM27C512 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 FM27C512 is configured in the standard JEDEC EPROM
pinout which provides an easy upgrade path for systems which are
currently using standard EPROMs.
