Introduction
This datasheet contains the specifications for the 3 Volt 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.
The 3 Volt 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
V
CCQ location
• Maximum program and erase time specification for improved data storage.
