A valid address is not required for the first write cycle;
only the data 60h.
The process technology has changed to 0.23 µm, and
is indicated in the part number by the “D” suffix. The 70
ns speed option is now offered in the full voltage range
instead of the regulated voltage range. The 70 ns
devices are also now available in the industrial temper-
ature range. The 80 ns speed option has been deleted.
The extended temperature range is no longer available.
All other parameters and functions remain unchanged.
Erase and Programming Performance
In Note 2, the worst case endurance is now 1 million cycles.
Revision C+3 (August 1998)
Global
Added -70R speed option, and changed -80R speed
option to -80.
Ordering Information
Deleted the “U” designator from ordering part numbers
for FBGA devices.
