5 / 49 page  E SMART 3 ADVANCED BOOT BLOCK–WORD-WIDE 5 PRELIMINARY 1.0 INTRODUCTION This preliminary datasheet contains the specifications for the Advanced Boot Block flash memory family, which is optimized for low power, portable systems. This family of products features 1.8V–2.2V or 2.7V–3.6V I/Os and a low VCC/VPP operating range of 2.7V–3.6V for read and program/erase operations. In addition this family is capable of fast programming at 12V. Throughout this document, the term “2.7V” refers to the full voltage range 2.7V–3.6V (except where noted otherwise) and “VPP = 12V” refers to 12V ±5%. Section 1 and 2 provides an overview of the flash memory family including applications, pinouts and pin descriptions. Section 3 describes the memory organization and operation for these products. Finally, Sections 4, 5, 6 and 7 contain the operating specifications. 1.1 Smart 3 Advanced Boot Block Flash Memory Enhancements The new 4-Mbit, 8-Mbit, and 16-Mbit Smart 3 Advanced Boot Block flash memory provides a convenient upgrade from and/or compatibility to previous 4-Mbit and 8-Mbit Boot Block products. The Smart 3 product functions are similar to lower density products in both command sets and operation, providing similar pinouts to ease density upgrades. The Smart 3 Advanced Boot Block flash memory features • Enhanced blocking for easy segmentation of code and data or additional design flexibility • Program Suspend command which permits program suspend to read • WP# pin to lock and unlock the upper two (or lower two, depending on location) 4-Kword blocks • VCCQ input for 1.8V–2.2V on all I/Os. See Figure 1-4 for pinout diagrams and VCCQ location • Maximum program time specification for improved data storage. Table 1.
