The 3 Volt Advanced Boot Block flash memory, manufactured on Intel’s latest 0.18 µm
technology, represents a feature-rich solution at overall lower system cost. The 3 Volt Advanced
Boot Block flash memory products in x16 will be available in 48-lead TSOP and 48-ball CSP
packages. The x8 option of this product family will only be available in 40-lead TSOP and 48-
ball µBGA* packages. Additional information on this product family can be obtained by
accessing Intel’s website at: http://www.intel.com/design/flash.
Notice: This document contains preliminary information on new products in production. The
specifications are subject to change without notice. Verify with your local Intel sales office that
you have the latest datasheet before finalizing a design.

1.0 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
VCCQ location
• Maximum program and erase time specification for improved data storage.
