Intel’s word-wide Smart 5 boot block flash memory family provides 2-, 4-, and 8-Mbit memories featuring
high-density, low-cost, nonvolatile, read/write storage solutions for a wide range of applications. Their
asymmetrically-blocked architecture, flexible voltage, and extended cycling provide highly flexible
components suitable for embedded code execution applications, such as networking infrastructure and office
automation.
Based on Intel’s boot block architecture, the word-wide Smart 5 boot block memory family enables quick and
easy upgrades for designs that demand state-of-the-art technology. This family of products comes in
industry-standard packages: the 48-lead TSOP, ideal for board-constrained applications, and the rugged,
easy to handle 44-lead PSOP.
