ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed below may cause permanent
damage to the device. These are stress ratings only. Functional
operation of the device at these or any other conditions greater
than those indicated in the operational sections of this specifica-
tion is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the Blackfin processor features proprietary ESD protection circuitry, permanent damage may occur
on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
