REVISION SUMMARY
Revision A (January 1999)
Initial release.
Revision B (March 10, 1999)
Global
Revised document into full data sheet.
Revision B+1 (March 18, 1999)
In-System Sector Protect/Sector Unprotect
Algorithms figure
Added requirements for asserting address A5 and setting
OE# to V
IH
during both algorithms.
Command Definitions table
Added A5 requirement to definition for SA+ in the legend. In
the fourth cycle of the Sector Relock sequence, changed
address from XXX to SA+.
Sector Protect/Unprotect Timing Diagram
Modified drawing to indicate that OE# should be dropped to
V
IH
during the third cycle.
Revision B+2 (May 14, 1999)
Ordering Information
Changed the temperature range in the example to I.
Device Bus Operation table
Corrected the highest bit in the address range column header
to A18.
Command Definitions table
In Note 4, changed the address range for bits that are don’t
care to A18–A12.
DC Characteristics table
In Note 5, deleted reference to I
CC4
.
Read Operations Timings and Alternate CE#
Controlled Write Operations figures
Deleted RESET# waveform.
Revision B+3 (July 12, 1999)
Global
Deleted all references to the PDIP package. Changed data
sheet status to Preliminary.
In-System Sector Protect/Unprotect Algorithms
figure
Added tolerance specifications to the 150 μs and 15 ms waits.
Clarified that reading from the sector address during either
sector protect or unprotect algorithm requires an access time
of 1 μs.
Revision C (November 12, 1999)
AC Characteristics—Figure 11, Program
Operations Timing and Figure 12, Chip/Sector
Erase Operations
Deleted t
GHWL
and changed OE# waveform to start at high.
Physical Dimensions
Replaced figures with more detailed illustrations.
Revision D (February 22, 2000)
Global
The “preliminary” designation was removed from the docu-
ment. Parameters are now stable, and only speed, package,
and temperature range combinations are expected to change
in future data sheet revisions.
Revision E (November 29, 2000)
Added table of contents.
Ordering Information
Deleted burn-in option.
Table , Command Definitions
In Note 4, corrected lower address bit of don’t care range to
A11.
Revision E+1 (March 28, 2005)
Global
Added Colophon
Updated Trademark
Ordering Information
Added Pb-free temperature ranges for Industrial and
Extended packaging
Added Valid Combination Codes
Revision E+2 (July 26, 2005)
Global
Removed all 55 ns information from the Datasheet.
