REVISION SUMMARY

Revision E (January 1998)

Distinctive Characteristics

Changed typical read and program/erase current

specifications.

Device now has a guaranteed minimum endurance of

1,000,000 write cycles.

In-System Sector Protect/Unprotect

Algorithm Figure

Corrected A6 to 0, Changed wait specification to 150

µs on sector protect and 15 ms on sector unprotect.

DC Characteristics

Changed typical read and program/erase current

specifications.

AC Characteristics

Alternate CE# Controlled Erase/Program Operations:

Changed tCP to 35 ns for 70R, 80, and 90 speed

options.

Erase and Programming Performance

Device now has a guaranteed minimum endurance of

1,000,000 write cycles.

Physical Dimensions

Corrected dimensions for package length and width in

FBGA illustration (standalone data sheet version).

Revision E+1 (March 1998)

In-System Sector Protect/Unprotect

Algorithms Figure

In the sector protect algorithm, added a “Reset

PLSCNT=1” box in the path from “Protect another

sector?” back to setting up the next sector address.

DC Characteristics

Changed Note 1 to indicate that OE# is at VIH for the

listed current.

AC Characteristics

Erase/Program Operations; Alternate CE# Controlled

Erase/Program Operations: Corrected the notes

reference for tWHWH1 and tWHWH2. These parameters

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.

Figure 23, Sector Protect/Unprotect

Timing Diagram

A valid address is not required for the first write cycle;

only the data 60h.

Erase and Programming Performance

In Note 2, the worst case endurance is now 1 million

cycles.

Revision F (January 1999)

Global

Changed references for process technology to “0.32

µm.”

Replaced the 70R ns regulated voltage speed option

with 70 ns full voltage speed option.

Distinctive Characteristics

Added 20-year data retention bullet.

Connection Diagrams

Reverse TSOP: Modified markings.

FBGA: Replaced Bump side (bottom) view with top

view.

Ordering Information

Valid Combinations for FBGA Packages: New Table.

DC Characteristics—CMOS Compatible

ICC1, ICC2, ICC3, ICC4, ICC5: Added Note 2 “Maximum

ICC specifications are tested with VCC = VCCmax”.

ICC3, ICC4: Deleted VCC = VCCmax.

Physical Dimensions

Changed package drawing to FBB048.

Revision F+1 (February 1999)

Physical Dimensions

Corrected ball grid layout on FBB048 drawing. Added

“048” to drawing title.

Revision F+2 (February 1999)

Distinctive Characteristics, Operating

Ranges

Corrected to indicate that the VCC voltage range for

all devices is 2.7–3.6 V.

Revision F+3 (July 2, 1999)

Global

Added references to availability of device in Known

Good Die (KGD) form.

Revision F+4 (July 26, 1999)

Global

Added the 70R speed option, which is available in the

extended temperature range.

Ordering Information

Deleted the extended temperature range from the

FBGA valid combinations.

Revision G (November 10, 1999)

Ordering Information

Deleted commercial and industrial temperature

ranges from the 70R speed option.
