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 S29AL016D 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 48-ball FBGA, and 48-pin TSOP packages. The word-wide data (x16) appears on
DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed in-
system with the standard system 3.0 volt V
CC
supply. A 12.0 V V
PP
or 5.0 V
CC
are not required for write or
erase operations. The device can also be programmed in standard EPROM programmers.
The device offers access times of 70 ns and 90 ns allowing high speed microprocessors to operate without
wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and
output enable (OE#) controls.
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 program and erase operations.
The S29AL016D 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 to an internal state-machine that controls the erase and programming circuitry. Write
cycles also internally latch addresses and data needed for the programming and erase operations. Reading
data out of the device is similar to reading from other Flash or EPROM devices.
Device programming occurs by executing the program command sequence. This initiates the
Embedded
Program
algorithm—an internal algorithm that automatically times the program pulse widths and verifies
proper cell margin. The
Unlock Bypass
mode facilitates faster programming times by requiring only two write
cycles to program data instead of four.
Device erasure occurs by executing the erase command sequence. This initiates the
Embedded Erase
algorithm—an internal algorithm that automatically preprograms the array (if it is not already programmed)
before executing the erase operation. During erase, the device automatically times the erase pulse widths
and verifies proper cell margin.
The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin,
or by reading the DQ7 (Data# Polling) and DQ6 (toggle)
status bits.
After a program or erase cycle has been
completed, the device is ready to read array data or accept another command.
The
sector erase architecture
allows memory sectors to be erased and reprogrammed without affecting the
data contents of other sectors. The device is fully erased when shipped from the factory.
Hardware data protection
measures include a low V
CC
detector that automatically inhibits write operations
during power transitions. The
hardware sector protection
feature disables both program and erase
operations in any combination of the sectors of memory. This can be achieved in-system or via programming
equipment.
The
Erase Suspend/Erase Resume
feature enables the user to put erase on hold for any period of time to
read data from, or program data to, any sector that is not selected for erasure. True background erase can
thus be achieved.
The
hardware RESET# pin
terminates any operation in progress and resets the internal state machine to
reading array data. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also
reset the device, enabling the system microprocessor to read the boot-up firmware from the Flash memory.
The device offers two power-saving features. When addresses have been stable for a specified amount of
time, the device enters the
automatic sleep mode.
The system can also place the device into the
standby
mode.
Power consumption is greatly reduced in both these modes.
Spansion’s Flash technology combines years of Flash memory manufacturing experience to produce the
highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a
sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron
injection.
