REVISION SUMMARY

Revision A (June 1, 1999)

Initial release.

Revision A+1 (June 25, 1999)

General Description

Corrected the device density in the first paragraph.

Command Definitions

Reading Array Data in Burst Mode: Added reference to

Figure 3 in the first paragraph.

Revision B (November 29, 1999)

Global

All speed options are now offered only at the regulated

voltage range of 3.0 to 3.6 V. The 90 and 120 speed

options now have a tOE of 26 ns at the industrial tem-

perature range. The 70 ns speed option is now avail-

able at the extended temperature range.

AC Characteristics

In Figures 17 and 18, deleted tGHWL; modified OE#

waveform.

Physical Dimensions

Updated drawing of SSOP to new version.

Revision C (June 20, 2000)

Global

The “advance information” data sheet designation has

been changed to “preliminary.” Only minor parameter

changes, if any, may occur. Speed, package, and tem-

perature range combinations may also change in future

data sheet revisions.

Distinctive Characteristics

Changed burst access time specification for the 65R

speed option in the industrial temperature range from

19 to 18 ns.

Product Selector Guide

Replaced tOE with tBACC to more clearly distinguish

burst mode access from asynchronous access times.

Note however, that in burst mode, tOE and tBACC spec-

ifications are identical. Changed tBACC for the 65R

speed option in the industrial temperature range from

19 to 18 ns.

Ordering Information

Burn-in processing is no longer available.

Requirements for Reading Array Data Array in

Asynchronous (Non-Burst) Mode

Clarified the description of how to terminate a burst

mode read operation.

Burst Mode Read with 40 MHz CLK figure

Changed tBACC for the 65R speed option in the indus-

trial temperature range from 19 to 18 ns.

Read Operations table

Changed tOE and tDF for the 65R speed option in the

industrial temperature range from 19 to 18 ns.

Burst Mode Read table

Changed tOE and tBACC for the 65R speed option in the

industrial temperature range from 19 to 18 ns.

Burst Mode Read figure

Corrected BAA# waveform to return high before the

final clock cycle shown.

Erase and Programming Performance table, Erase

and Program Operations table, Alternate CE# Con-

trolled Erase and Program Operations table

Resolved differences in typical sector erase times. The

typical sector erase time for all sectors is 3 sec.

Revision C+1 (November 16, 2000)

Global

Deleted Preliminary status from document. Added

table of contents. Added Figure 1, In-system Sector

Protect/Unprotect Algorithms figure to document (was

missing from previous revisions).

Revision C+2 (July 22, 2002)

Pin Description, IND# End of Burst Indicator

Clarified description of IND# function.

Table 1, Device Bus Operations

In burst read operations section, changed BAA# to “H”

for “Load star ting Burst Address” and Terminate

Current Burst Read Cycle; Start New Burst Read

Cycle.”

Requirements for Reading Array Data in Synchro-

nous (Burst) Mode

Modified section to clarify the description of the IND#

and burst read functions.

Burst Sequence Table

Deleted table.

Revision C+3 (November 22, 2002)

Distinctive Characteristics

Changed endurance to 1 million cycles.

Erase Sus p e n d / Eras e Res u me Comma nd

Sequence

Noted that only asynchronous reads are allowed during

the erase suspend mode, added asynchronous mode

and burst mode section.
