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¨C2.2V or 2.7V¨C3.6V I/Os and a low VCC/VPP operating range of 2.7V¨C3.6V 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¨C3.6V (except where noted otherwise) and ¡°VPP = 12V¡± refers to 12V ¡À5. 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.
