REVISION SUMMARY

Revision A (September 1998)

Initial release.

Revision B (December 1998)

Global

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.

Ordering Information

Deleted commercial temperature rating.

Revision D (May 17, 1999)

Global

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.

Distinctive Characteristics

Changed device endurance from program/erase cycles

to erase cycles.

Block Diagram

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.

Pin Configuration

Clarified the explanation of IND#.

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.

Device Bus Operations table: In the notes, deleted ref-

erence to BYTE# pin.

Sector Address table: Added sector address bit set-

tings for A19–A12.

Common Flash Memory Interface (CFI)

Corrected data for the following hex CFI addresses: 28,

38, 39, 3C.

Command Definitions

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.

Absolute Maximum Ratings

Corrected the maximum VCC rating to +4.0 V, and the

maximum all other pins rating to +5.5 V.

DC Characteristics table

Corrected the maximum rating for VIH to 5.5 V.

AC Characteristics

In the read operations and burst mode operations

tables, reflected the global changes in speed options

(see the “global” revision entry).

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.

Revision D+1 (July 2, 1999)

Command Definitions

Reading Array Data in Burst Mode: Added reference to

figure 3 to the first paragraph.

Revision E (November 2, 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 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.

AC Characteristics

In figures 17 and 18, deleted tGHWL. Modified OE#

waveform.

Physical Dimensions

Updated drawing of SSOP to new version.
