General Description
The FM27C512 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 FM27C512 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 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.
