REVISION SUMMARY FOR AM29F100
Revision B+1
Product Selector Guide
Replaced the -75 column (70 ns, 5%) with the -70 col-
umn (70 ns, 10%).
Ordering Information, Standard Products
The -70 designation is now listed in the part number ex-
ample.
Valid Combinations: Replaced the -75 combinations
with -70. The 70 ns speed grade is now available in the
same combinations as the other speed grades.
Operating Ranges
V
to -70.
AC Characteristics
Read Only Operations: Changed the -75 column head
to -70. All parameters remain the same.
Figure 7, Test Conditions: Changed C
75 to -70.
Write/Erase/Program Operations: Changed the -75
column head to -70. Changed byte programming and
chip/sector erase times (t
tively).
Switching Waveforms

Erase and Programming Performance
Combined sector and chip erase times, added word
programming times and erase/program cycle times.
Updated specifications.
Revision C
Global
Made formatting and layout consistent with other data
sheets. Used updated common tables and diagrams.
Revision C+1
Table 5, Command Definitions
Address bits A0–A14 are required for unlock cycles.
Therefore, addresses for second and fifth write cycles
are 2AAAh in word mode and 5555h in byte mode. Ad-
dresses for first, third, fourth, and sixth cycles are
5555h in word mode and AAAAh in byte mode. Read
cycles are not affected. Deleted Note 5 to reflect the
correction.
