REVISION HISTORY
DATE
DESCRIPTION
111003
New product release.
032204
DC Electrical Characteristics table: Corrected typo—Under Supply Current for Active and Idle Mode,
changed Units from “A” to “mA.”
Note 15: Changed number of external clock cyles per system clock and minimum external clock
speeds.
Flash Memory Programming Characteristics table: Removed Note 20 (room temperature only) from the
Data Retention parameter.
060204
Changed Write/Erase Endurance parameter from 20,000 cycles to 10,000 cycles.
Removed original Table 5. Parallel Programming Instruction Set, and replaced it with a paragraph
introducing the subject and advising interested parties to contact the factory for more information.
Clarified IAP programming sequence.
060805
Added lead-free devices to Ordering Information table.
091906
Removed references to DS89C440 and/or added “Contact factory or replace with DS89C430 or
DS89C450.”
040507
Added clarification to the Security Features section and Table 3 that flash security levels 1, 2, and 3
should not be used when executing external code (page 22); corrected Figure 8 to show PSEN high
through the second machine cycle (page 28).
