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 I
CC3
and I
CC4
, 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 t
WHWH1
and t
WHWH2
. These param-
eters are 100% tested. Corrected the note reference for
t
VCS
. This parameter is not 100% tested.
Temporary Sector Unprotect Table
Added note reference for t
VIDR
. This parameter is not
100% tested.
