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, 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 Inc. 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 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 con-
tacting 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 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 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 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 sales office.

General Description
The S29AL016M is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152
bytes or 1,048,576 words. The device is offered in a 48-ball Fine-pitch BGA, 64-
ball Fortified BGA, and 48-pin TSOP packages. The word-wide data (x16) appears
on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. The device re-
quires only a
single 3.0 volt power supply
for both read and write functions,
designed to be programmed in-system with the standard system 3.0 volt V
CC
sup-
ply. The device can also be programmed in standard EPROM programmers.
The device offers access times of 90 and 100 ns. To eliminate bus contention the
device has separate chip enable (CE#), write enable (WE#) and output enable
(OE#) controls.
The device is entirely command set compatible with the
JEDEC single-power-
supply Flash standard.
Commands are written to the device using standard
microprocessor write timing. Write cycles also internally latch addresses and data
needed for the programming and erase operations.
The
sector erase architecture
allows memory sectors to be erased and repro-
grammed without affecting the data contents of other sectors. The device is fully
erased when shipped from the factory.
Device programming and erasure are initiated through command sequences.
Once a program or erase operation has begun, the host system need only poll
the DQ7 (Data# Polling) or DQ6 (toggle)
status bits
or monitor the
Ready/
Busy# (RY/BY#)
output to determine whether the operation is complete. To
facilitate programming, an
Unlock Bypass
mode reduces command sequence
overhead by requiring only two write cycles to program data instead of four.
Hardware data protection
measures include a low V
CC
detector that automati-
cally inhibits write operations during power transitions. The hardware sector
protection feature disables both program and erase operations in any combina-
tion of sectors of memory. This can be achieved in-system or via programming
equipment.
The
Erase Suspend/Erase Resume
feature allows the host system to pause an
erase operation in a given sector to read or program any other sector and then
complete the erase operation. The
Program Suspend/Program Resume
fea-
ture enables the host system to pause a program operation in a given sector to
read any other sector and then complete the program operation.
The
hardware RESET# pin
terminates any operation in progress and resets the
device, after which it is then ready for a new operation. The RESET# pin may be
tied to the system reset circuitry. A system reset would thus also reset the de-
vice, enabling the host system to read boot-up firmware from the Flash memory
device.
The device reduces power consumption in the
standby mode
when it detects
specific voltage levels on CE# and RESET#, or when addresses have been stable
for a specified period of time.
The
Secured Silicon Sector
provides a 128-word/256-byte area for code or
data that can be permanently protected. Once this sector is protected, no further
changes within the sector can occur.
MirrorBit flash technology combines years of Flash memory manufacturing expe-
rience to produce the highest levels of quality, reliability and cost effectiveness.
The device electrically erases all bits within a sector simultaneously via hot-hole
assisted erase. The data is programmed using hot electron injection.
