Common Flash Memory Interface (CFI)
REVISION SUMMARY
Corrected data for the following hex CFI addresses: 28,
38, 39, 3C.
Revision A (September 1998)
Initial release.
Command Definitions
Revision B (December 1998)
Global
Reorganized and rewrote the “Reading Array Data”
section into two sections entitled “Reading Array Data
in Non-burst Mode” and “Reading Array Data in Burst
Mode”. Added burst mode read figures comparing
system frequency and device speed. Added burst
mode status to autoselect command sequence in
command definitions table.
Expanded data sheet into full version.
Revision C (December 1998)
Global
Added a separate set of read access specifications for
devices at industrial temperature range. Changed read
access specifications for 90 and 120 ns devices at
extended temperature range to 28 ns.
Absolute Maximum Ratings
Corrected the maximum VCC rating to +4.0 V, and the
maximum all other pins rating to +5.5 V.
Ordering Information
DC Characteristics table
Deleted commercial temperature rating.
Corrected the maximum rating for VIH to 5.5 V.
Revision D (May 17, 1999)
AC Characteristics
Global
In the read operations and burst mode operations
tables, reflected the global changes in speed options
(see the “global” revision entry).
Changed data sheet status to preliminary. Deleted the
70R speed option. Deleted the 70 speed option at
extended temperature range. Added the 90R and 120R
speed options at extended temperature range. Deleted
the 90 and 120 speed options at extended temperature
range.
Burst Mode Read figure
Corrected figure. Deleted note; OE# and BAA# should
not be tied together. LBA# should be returned high
after it coincides with a rising edge of CLK. BAA#
should not be asserted before the first word of data
appears on the bus. The data is held on the outputs for
only tBDH after the next clock.
Distinctive Characteristics
Changed device endurance from program/erase cycles
to erase cycles.
Revision D+1 (July 2, 1999)
Block Diagram
Command Definitions
Deleted redundant path between state control and
erase voltage generator. Added sector switch block.
Deleted RY/BY# buffer. VCC and VSS are now shown
properly.
Reading Array Data in Burst Mode: Added reference to
figure 3 to the first paragraph.
Revision E (November 2, 1999)
Global
Pin Configuration
Clarified the explanation of IND#.
All speed options are now offered only at the regulated
voltage range of 3.0 to 3.6 V. The 90 and 120 ns speed
options now have a tOE of 26 ns at the industrial tem-
perature range. The 70R speed option is now available
at the extended temperature range.
Device Bus Operations
Reorganized and rewrote the following subsections:
Requirements for Reading Array Data, Read Mode,
Burst Mode Read, IND# End of Burst Indicator, and
Burst Mode Status. “Reading Array Data in Non-burst
Mode”. The Burst Mode Status section is now inte-
grated into the autoselect mode section.
AC Characteristics
In figures 17 and 18, deleted tGHWL. Modified OE#
waveform.
Device Bus Operations table: In the notes, deleted ref-
erence to BYTE# pin.
Physical Dimensions
Updated drawing of SSOP to new version.
Sector Address table: Added sector address bit set-
tings for A19–A12.
