Data Sheet
July 2003
The following document specifies Spansion memory products that are now offered by both Advanced
Micro Devices and Fujitsu. Although the document is marked with the name of the company that orig-
inally developed the specification, these products will be offered to customers of both AMD and
Fujitsu.
Continuity of Specifications
There is no change to this datasheet as a result of offering the device as a Spansion product. Any
changes that have been made are the result of normal datasheet improvement and are noted in the
document revision summary, where supported. Future routine revisions will occur when appropriate,
and changes will be noted in a revision summary.
Continuity of Ordering Part Numbers
AMD and Fujitsu continue to support existing part numbers beginning with “Am” and “MBM”. To order
these products, please use only the Ordering Part Numbers listed in this document.
For More Information
Please contact your local AMD or Fujitsu sales office for additional information about Spansion
memory solutions.
Publication Number 22366 Revision B Amendment +8 Issue Date September 20, 2002

DEVICE BUS OPERATIONS
This section describes the requirements and use of
the device bus operations, which are initiated through
the internal command register. The command register
itself does not occupy any addressable memory loca-
tion. The register is a latch used to store the com-
mands, along with the address and data information
needed to execute the command. The contents of the
register serve as inputs to the internal state machine.
The state machine outputs dictate the function of the
device. Table 1 lists the device bus operations, the in-
puts and control levels they require, and the resulting
output. The following subsections describe each of
these operations in further detail.

Legend: L = Logic Low = VIL, H = Logic High = VIH, VID = 8.512.5 V, VHH = 11.512.5 V, X = Dont Care, SA = Sector Address,
AIN = Address In, DIN = Data In, DOUT = Data Out
Notes:
1. Addresses are A21:A0. Sector addresses are A21:A15.
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the Sector Group
Protection and Unprotectionsection.
3. If WP# = VIL, the first or last sector remains protected. If WP# = VIH, the first or last sector will be protected or unprotected as
determined by the method described in Sector Group Protection and Unprotection. All sectors are unprotected when shipped
from the factory (The SecSi Sector may be factory protected depending on version ordered.)
4. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm (see Figure 2).
VersatileIO(VIO) Control
The VersatileIO(VIO) control allows the host system
to set the voltage levels that the device generates and
tolerates on CE# and DQ I/Os to the same voltage
level that is asserted on VIO. VIO is available in two
configurations (1.82.9 V and 3.05.0 V) for operation
in various system environments.
For example, a VI/O of 4.55.0 volts allows for I/O at
the 5 volt level, driving and receiving signals to and
from other 5 V devices on the same data bus.
Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the CE# and OE# pins to VIL. CE# is the power
control and selects the device. OE# is the output con-
trol and gates array data to the output pins. WE#
should remain at VIH.
The internal state machine is set for reading array data
upon device power-up, or after a hardware reset. This
ensures that no spurious alteration of the memory
content occurs during the power transition. No com-
mand is necessary in this mode to obtain array data.
Standard microprocessor read cycles that assert valid
addresses on the device address inputs produce valid
