Preliminary Technical Data
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.

ESD SENSITIVITY
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADSP-BF538/ADSP-BF538F processors feature 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.
