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, 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 LLC 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 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 contacting 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 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 will contain a combination of products with different designations (Advance Information, 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 VIO range. Changes may also include those needed to clarify a description or to correct a typographical error or incorrect 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 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 AMD or Fujitsu sales office.

General Description
The S29AL032D is a 32 megabit, 3.0 volt-only flash memory device, organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. Word mode data appears on DQ0-DQ15; byte mode data appears on DQ0-DQ7. The device is designed to be programmed in-system with the standard 3.0 volt VCC supply, and can also be programmed in standard EPROM programmers. The device is available with access times as fast as 70 ns. The devices are offered in 40-pin TSOP, 48-pin TSOP and 48-ball FBGA packages. Standard control pins- chip enable (CE#), write enable (WE#), and output enable (OE#)-control normal read and write operations, and avoid bus contention issues. The device requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the pro-gram and erase operations.
S29AL032D Features
The Secured Silicon Sector is an extra sector capable of being permanently locked by Spansion or customers. The Secured Silicon Indicator Bit (DQ7) is permanently set to a 1 if the part is factory locked, and set to a 0 if customer lockable. This way, customer lockable parts can never be used to replace a factory locked part. Note that the S29AL032D has a Secured Silicon Sector size of 128 words (256 bytes). Factory locked parts provide several options. The Secured Silicon Sector may store a secure, random 16 byte ESN (Electronic Serial Number), customer code (programmed through the Spansion programming service), or both. The S29AL032D is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input
