The Intel® 5 Volt Boot Block Flash memory family provides 2-, 4-, and 8-Mbit memories featuring highdensity, 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® 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 industrystandard 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. NOTE: This document formerly known as Smart 5 Boot Block Flash Memory Family 2, 4, 8 Mbit.
