1.1
The 5 Volt FlashFile memory family maintains
backwards-compatibility with Intel’s 28F008SA. Key
enhancements include:
They share a compatible status register, software
commands, and pinouts. These similarities enable
a clean upgrade from the 28F008SA to 5 Volt
FlashFile products. When upgrading, it is important
to note the following differences:

The 5 Volt FlashFile memory family provides
density upgrades with pinout compatibility for the 4-
, 8-, and 16-Mbit densities. The 28F004S5,
28F008S5, and 28F016S5 are high-performance
memories arranged as 512 Kbyte, 1 Mbyte, and
2 Mbyte of 8 bits. This data is grouped in eight,
sixteen, and thirty-two 64-Kbyte blocks which are
individually erasable, lockable, and unlockable in-

A Command User Interface (CUI) serves as the
interface between the system processor and
internal operation of the device. A valid command
sequence written to the CUI initiates device
automation. An internal Write State Machine (WSM)
