The Intel
3 Volt FlashFile memory provides high-density, low-cost, nonvolatile, read/write storage
solutions for a wide range of applications. The 3 Volt 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 3 Volt FlashFile memory offers 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
0.4
μ
m ETOX V process technology. It comes in the
industry-standard 56-lead SSOP and
μ
BGA packages. In addition, the 16-Mb device is available in the
industry-standard 56-lead TSOP package.
