REVISION SUMMARY

Revision A (July 1997)

Initial release.

Revision B (January 1998)

Global

Formatted for consistency with other 5.0 volt-only

data sheets.

Figure 9, Read Operation Timings

Corrected RESET# waveform so that it is high for the

duration of the read cycle.

Figure 11, Chip/Sector Erase Operation Timings

Corrected data unlock cycle in diagram to 55h.

Figure 17, Alternate CE# Controlled Program

Operation Timings

Corrected command for sector erase to 30h, chip erase

to 10h.

Revision C (January 1998)

Standby Mode

Removed sentence in first paragraph referring to

RESET# pulse.

Sector Group Protection/Unprotection, Temporary

Sector Group Unprotect

Changed references from “sector” to “sector group”.

Corrected text to indicate sector groups are composed

of two adjacent sectors.

Revision D (May 1998)

Distinctive Characteristics

Changed minimum 100K write/erase cycles guaran-

teed to 1,000,000.

DC Characteristics, CMOS Compatible

For ICC3 and ICC4, the voltage tolerances given for CE#

and RESET# are now ±0.5 V.

AC Characteristics

Erase/Program Operations; Erase and Program Oper-

ations Alternate CE# Controlled Writes: Corrected the

notes reference for tWHWH1 and tWHWH2. These param-

eters are 100% tested. Corrected the note reference for

tVCS. This parameter is not 100% tested.

Temporary Sector Unprotect Table

Added note reference for tVIDR. This parameter is not

100% tested.

Command Definitions

Corrected the shift in the table header.

Erase and Programming Performance

Changed minimum 100K program and erase cycles

guaranteed to 1,000,000.

Revision E (January 1999)

Global

Updated for CS39S process technology.

Distinctive Characteristics

Added:

■ 20-year data retention at 125°C

— Reliable operation for the life of the system

DC Characteristics—CMOS Compatible

Added note “For CMOS mode only, ICC3 = ICC4 = 20 µA

max at extended temperatures (> +85°C)”.

DC Characteristics—TTL/NMOS Compatible and

CMOS Compatible

ICC1, ICC2, ICC3, ICC4: Added Note 2 “Maximum ICC

specifications are tested with VCC = VCCmax”.

ICC3, ICC4: Deleted VCC = VCCMax.

Revision E+1 (March 23, 1999)

Operating Ranges

The temperature ranges are now specified as ambient.

Revision E+2 (April 9, 1999)

Ordering Information, Operating Ranges

Added the extended temperature range.

Revision F (November 15, 1999)

AC Characteristics—Figure 11. Program

Operations Timing and Figure 12. Chip/Sector

Erase Operations

Deleted tGHWL and changed OE# waveform to start at

high.

Physical Dimensions

Replaced figures with more detailed illustrations.

Revision F+1 (May 18, 2000)

DC Characteristics

TTL/NMOS Compatible: The ICC2 specifications are

now identical to those for CMOS compatible.

Revision G (December 4, 2000)

Added table of contents.

Ordering Information

Deleted burn-in option.
