Description

Intel's Word-Wide FlashFile™ memory family provides high-density, low-cost, nonvolatile, read/write storage solutions for a wide range of applications. 28F320S5 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, 28F320S5 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.

28F320S5 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.
