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.
