Intel’s Word-Wide FlashFile™ memory family provides high-density, low-cost, nonvolatile, read/write storage
solutions for a wide range of applications. The word-wide memories are available at various densities in the
same package type. Their symmetrically-blocked architecture, 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 memories offer three levels of protection: absolute protection with V
PP
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. In addition, the 16-Mb device is available in the industry-standard 56-lead
TSOP package.
