Notice On Data Sheet Designations
Spansion LLC issues data sheets with Advance Information or Preliminary designations to advise
readers of product information or intended specifications throughout the product life cycle, includ-
ing 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 de-
sign. 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 LLC is developing one or more spe-
cific 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 prod-
uct may discontinue. Spansion LLC therefore places the following conditions upon Advance
Information content:
“This document contains information on one or more products under development at Spansion LLC. The
information is intended to help you evaluate this product. Do not design in this product without con-
tacting the factory. Spansion LLC 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 as-
pects 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 modifica-
tions due to changes in technical specifications.”
Combination
Some data sheets will contain a combination of products with different designations (Advance In-
formation, Preliminary, or Full Production). This type of document will distinguish these products
and their designations wherever necessary, typically on the first page, the ordering information
page, and pages with DC Characteristics table and 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 incor-
rect specification. Spansion LLC applies the following conditions to documents in this category:
“This document states the current technical specifications regarding the Spansion product(s) described
herein. Spansion LLC deems the products to have been in sufficient production volume such that sub-
sequent 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 AMD or Fujitsu
sales office.

Data Sheet
ADVANCE
INFORMATION
General Description
The Spansion™ S29WS-K devices are 90 nm 1.8 Volt-only, Simultaneous Read/Write, Burst Mode Flash memory devices.
These products use a 32-word Write Buffer for faster programming and are capable of performing simultaneous Read/
Write operations with zero latency on two separate banks. These devices offer fast burst access of 7.0 ns with initial
latency of 54.5 ns for 108 MHz operation and are organized as 16/8/4 Mwords of 16 bits.
Distinctive Characteristics
Architectural Advantages
Manufactured on 90 nm Floating Gate process
technology
Single 1.8-volt read, program and erase (1.7
– 1.95 V)
32-Word Write Buffer
Single power supply operation
— Full Voltage range: 1.7 to 1.95 V read, erase, and
program operations for battery-powered applications
Simultaneous Read/Write Operation
— Data can be continuously read from one bank while
executing erase/program functions in another bank
— Zero latency switching from write to read operations
Programable Burst Interface
— Linear Burst: 8, 16, and 32 words with or without
wrap-around
— Continuous Sequential Burst
Architecture
— S29WS256K: 16 Banks consisting of 8 sectors of
16-KWords and 508 sectors of 32KWords
— S29WS128K: 8 Banks consisting of 8 sectors of
16-KWords and 252 sectors of 32KWords
— S29WS064K: 8 Banks consisting of 8 sectors of
16-KWords and 124 sectors of 32KWords
256-Word Secured Silicon Sector region
— 128 words factory locked
— 128 words customer locked
Data retention: 20 years typical
Cycling Endurance: 100,000 cycles per sector
typical
Packages
— S29WS256/128K: 84 Ball MCP compatible
FBGA (8 mm x 11.6 mm)
— S29WS064K: 80 Ball MCP compatible
FBGA (7mm x 9 mm)
Software Features
Data# Polling and toggle bits
— Provides a software method of detecting program
and erase operation completion
Erase Suspend/Resume
— Suspends an erase operation to read data from, or
program data to, a sector that is not being erased
Program Suspend/Resume
— Suspends a programming operation to read data
from a sector other than the one being programmed
Unlock Bypass Program command
— Reduces overall programming time when issuing
multiple program command sequences
Hardware Features
Handshaking feature available
— Provides host system with minimum possible latency
by monitoring RDY
Hardware reset input (Reset#)
— Hardware method to reset the device for reading
array data
WP# input
— Write protect (WP#) function allows protection of
eight outermost boot sectors, four at top and four at
bottom of memory, regardless of sector protect
status
ACC input: All sectors locked when ACC = V
IL
Low V
CC
write inhibit
Security Features
Advance Sector Protection consists of the two
following modes of operation
— Persistent Sector Protection method to lock
combinations of individual sectors to prevent
program or erase operations
— Password Sector Protection method to lock
combinations of individual sectors to prevent program
or erase operations within that sector using a user-
defined 64-bit password
Additional Features
Program Operation
— Ability to perform synchronous and asynchronous
write operation independent of burst control register
setting
