It is organized as 128K-words of 8 bits each. FM27C010's pin-compatibility with byte-wide JEDEC EPROMs enables upgrades through 8 Mbit EPROMs. The "Don't Care" feature during read operations allows memory expansions from 1M to 8M bits with no printed circuit board
changes.
The FM27C010 can directly replace lower density 28-pin EPROMs by adding an A16 address line and VCC jumper. During the normal read operation PGM and VPP are in a "Don't Care" state which allows higher order addresses, such as A17, A18, and A19 to be connected without affecting the normal read operation. This allows memory upgrades to 8M bits without hardware changes.
The FM27C010 is also offered in a 32-pin plastic DIP with the same upgrade path. The FM27C010 provides microprocessor-based systems exten-sive storage capacity for large portions of operating system and application software. Its 70 ns access time provides no-wait-state operation with high-performance CPUs. The FM27C010 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.
