SMART 3 ADVANCED BOOT BLOCK

PRELIMINARY

1.0

INTRODUCTION

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.

Flash Memory Enhancements

The Smart 3 Advanced Boot Block flash memory

features

• Enhanced blocking for easy segmentation of

code and data or additional design flexibility

• Program Suspend to Read command

• VCCQ input of 1.65 V–2.5 V on all I/Os. See

Figures 1 through 4 for pinout diagrams and

VCCQ location

• Maximum program and erase time specification

for improved data storage.
