Intel’s Word-Wide FlashFile™ memory family provides high-density, low-cost, non-volatile, read/write storage
solutions for a wide range of applications. The Word-Wide FlashFile memories are available at various
densities in the same package type. Their symmetrically-blocked architecture, flexible voltage, and extended
cycling provide highly flexible components suitable for resident flash arrays, SIMMs, and memory cards.
Enhanced suspend capabilities provide an ideal solution for code or data storage applications. For secure
code storage applications, such as networking, where code is either directly executed out of flash or
downloaded to DRAM, the Word-Wide FlashFile memories offer three levels of protection: absolute protection
with VPP at GND, selective block locking, and program/erase lockout during power transitions. These
alternatives give designers ultimate control of their code security needs.
This family of products is manufactured on Intel’s 0.4 µm ETOX™ V process technology. It comes in the
industry-standard 56-lead SSOP and µBGA packages. In addition, the 16-Mb device is available in the
industry-standard 56-lead TSOP package.
