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, in-
cluding 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 high-
light 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 doc-
ument 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 Informa-
tion 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 prod-
uct 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 Prelimi-
nary 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.

S29GLxxxA MirrorBit™ Flash Family

General Description
The S29GLxxxA family of devices are 3.0 V single power Flash memory manufac-
tured using 200 nm MirrorBit technology. The S29GL064A is a 64 Mb, organized
as 4,194,304 words or 8,388,608 bytes. The S29GL032A is a 32 Mb, organized
as 2,097,152 words or 4,194,304 bytes. Depending on the model number, the
devices have an 8-bit wide data bus only, 16-bit wide data bus only, or a 16-bit
wide data bus that can also function as an 8-bit wide data bus by using the BYTE#
input. The devices can be programmed either in the host system or in standard
EPROM programmers.
Access times as fast as 90 ns are available. Note that each access time has a spe-
cific operating voltage range (V
CC
) as specified in the
Product Selector Guide
and
the
Ordering Information
sections. Package offerings include 48-pin TSOP, 56-pin
TSOP, 48-ball fine-pitch BGA and 64-ball Fortified BGA, depending on model num-
ber. Each device has separate chip enable (CE#), write enable (WE#) and output
enable (OE#) controls.
Each device requires only a
single 3.0 volt power supply
for both read and
write functions. In addition to a V
CC
input, a high-voltage
accelerated program
(ACC)
feature provides shorter programming times through increased current on
the WP#/ACC input. This feature is intended to facilitate factory throughput dur-
ing system production, but may also be used in the field if desired.
The device is entirely command set compatible with the
JEDEC single-power-
supply Flash standard.
Commands are written to the device using standard mi-
croprocessor 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 automat-
ically 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 device,
enabling the host system to read boot-up firmware from the Flash memory
Previously, when calculating the altitude by air pressure, the microcontroller was used to achieve automatic zeroing.
