The IntelÂ® 5 Volt 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 IntelÂ® Boot Block architecture, the 5 Volt Boot Block Flash 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.
