*Stresses greater than those listed above 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

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 ADSP-21065L 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.

WARNING!
