Technology
Intel’s byte-wide Smart 3 FlashFile™ memory family renders a variety of density offerings in the same
package. The 4-, 8-, and 16-Mbit byte-wide FlashFile memories provide high-density, low-cost, nonvolatile,
read/write storage solutions for a wide range of applications. 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 4-, 8-, and 16-Mbit FlashFile memories offer three levels
of protection: absolute protection with VPP at GND, selective hardware block locking, or flexible software
block locking. 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. They come in
industry-standard packages: the 40-lead TSOP, ideal for board-constrained applications, and the rugged
44-lead PSOP. Based on the 28F008SA architecture, the byte-wide Smart 3 FlashFile memory family
enables quick and easy upgrades for designs that demand state-of-the-art technology.
