1.0 INTRODUCTION
1.1
Smart 3 Advanced Boot Block
Flash Memory Enhancements
This 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 1.65 V–2.5 V or 2.7 V–
3.6 V I/Os and a low VCC/VPP operating range of
2.7 V–3.6 V for read, program, and erase
operations. In addition this family is capable of fast
programming at 12 V. Throughout this document,
the term “2.7 V” refers to the full voltage range
2.7 V–3.6 V (except where noted otherwise) and
“VPP = 12 V” refers to 12 V ±5%. Section 1.0 and
2.0 provide an overview of the flash memory family
including applications, pinouts and pin descriptions.
Section 3.0 describes the memory organization and
operation for these products. Sections 4.0 and 5.0
contain the operating specifications. Finally,
Sections 6.0 and 7.0 provide ordering and other
reference information.
