Notice On Data Sheet Designations
Spansion Inc. issues data sheets with Advance Information or Preliminary designations to advise readers of
product information or intended specifications throughout the product life cycle, including development,
qualification, initial production, and full production. In all cases, however, readers are encouraged to verify
that they have the latest information before finalizing their design. The following descriptions of Spansion data
sheet designations are presented here to highlight their presence and definitions.
Advance Information
The Advance Information designation indicates that Spansion Inc. is developing one or more specific
products, but has not committed any design to production. Information presented in a document with this
designation is likely to change, and in some cases, development on the product may discontinue. Spansion
Inc. therefore places the following conditions upon Advance Information content:
“This document contains information on one or more products under development at Spansion Inc.
The information is intended to help you evaluate this product. Do not design in this product without
contacting the factory. Spansion Inc. reserves the right to change or discontinue work on this proposed
product without notice.”
Preliminary
The Preliminary designation indicates that the product development has progressed such that a commitment
to production has taken place. This designation covers several aspects of the product life cycle, including
product qualification, initial production, and the subsequent phases in the manufacturing process that occur
before full production is achieved. Changes to the technical specifications presented in a Preliminary
document should be expected while keeping these aspects of production under consideration. Spansion
places the following conditions upon Preliminary content:
“This document states the current technical specifications regarding the Spansion product(s)
described herein. The Preliminary status of this document indicates that product qualification has been
completed, and that initial production has begun. Due to the phases of the manufacturing process that
require maintaining efficiency and quality, this document may be revised by subsequent versions or
modifications due to changes in technical specifications.”
Combination
Some data sheets contain a combination of products with different designations (Advance Information,
Preliminary, or Full Production). This type of document distinguishes these products and their designations
wherever necessary, typically on the first page, the ordering information page, and pages with the DC
Characteristics table and the AC Erase and Program table (in the table notes). The disclaimer on the first
page refers the reader to the notice on this page.
Full Production (No Designation on Document)
When a product has been in production for a period of time such that no changes or only nominal changes
are expected, the Preliminary designation is removed from the data sheet. Nominal changes may include
those affecting the number of ordering part numbers available, such as the addition or deletion of a speed
option, temperature range, package type, or V
IO
range. Changes may also include those needed to clarify a
description or to correct a typographical error or incorrect specification. Spansion Inc. applies the following
conditions to documents in this category:
“This document states the current technical specifications regarding the Spansion product(s)
described herein. Spansion Inc. deems the products to have been in sufficient production volume such
that subsequent versions of this document are not expected to change. However, typographical or
specification corrections, or modifications to the valid combinations offered may occur.”
Questions regarding these document designations may be directed to your local sales office.

General Description
The Spansion S29VS256/128R and S29XS256/128R are MirrorBit
®
Flash products fabricated on 65 nm process technology.
These burst mode Flash devices are capable of performing simultaneous read and write operations with zero latency on two
separate banks using multiplexed data and address pins. These products can operate up to 108 MHz and use a single V
CC
of
1.7 V to 1.95 V that makes them ideal for the demanding wireless applications of today that require higher density, better
performance, and lowered power consumption. The S29VS256/128R operates in ADM mode, while the S29XS256/128R can
operate in the AADM mode.
