Intel鈥檚 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鈥檚 boot block architecture, the 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 40-lead TSOP for very space-constrained 8-bit applications, 48-lead TSOP, ideal for
board-constrained higher-performance 16-bit applications, and the rugged, easy to handle 44-lead PSOP.
