Data
Sheet
Revision A + 4 (July 26, 2002)
Table 1, Device Bus Operations
Changed Synchronous Write to rising edge of CLK.
Writing Commands/Command Sequences
Added CLK as part of the asynchronous write operation system drive. Added VCC
and VIO Power-up and Power-down Sequencing section.
AC Characteristics
Changed tCHW erase/program time from Min to Max.
Figure 20, Asynchronous Program Operation Timings
Changed tCSW1 reference to WE# from AVD#.
Figure 21, Alternate Asynchronous Program Operation Timings
Changed to show CLK low after tCHW time.
Figure 22, Synchronous Program Operation Timings
Removed tACH. Changed tAHW to tAVSW and added tCSW2.
Figure 23, Alternate Synchronous Program Operation Timings
Changed tAVCH to tAVHC. Removed tACH.
DC Characteristics, CMOS Compatible
Corrected ICCB OE# = VIL to = VIH; switched Typ. and Max. values.
Revision B (October 31, 2002)
Global
Renamed Handshaking Enabled to Reduced Wait-State Handshaking. Renamed
non-Handshaking to Standard Handshaking
Product Selector Guide
Revised with renamed speed options and added Synchronous Access Time with
Reduced Wait-state Handshaking. Added Asynchronous Access Time.
Connection Diagram
Corrected pin numbers on bottom row.
Ordering Information
Revised with global changes. Revised Valid Combinations with updated ordering
information.
FBGA Capacitance
Added BGA Capacitance Table after Erase and Programming Performance.
Revision C (August 13, 2003)
Global
Updated formatting to new Spansion template. Changed data sheet status from
Advance Information to Preliminary.
Sector Lock/Unlock Command Sequence
Modified description of write cycles.
Reset Command
Modified last paragraph of section.
Table 13, Command Definitions
Added note references to Erase Suspend and Sector Lock/Unlock rows in table.
Replaced addresses “XXX” with “BA” in first and second cycles of Sector Lock/Un-
lock table row. Modified description of BA in legend.
