MAXIMUM POWER DISSIPATION

See Engineer-to-Engineer Note “Estimating Power Dissipation

for ADSP-21469 SHARC Processors” for detailed thermal and

power information regarding maximum power dissipation. For

information on package thermal specifications, see Thermal

Characteristics on Page 51.

ABSOLUTE MAXIMUM RATINGS

Stresses greater than those listed in Table 10 may cause perma-

nent damage to the device. These are stress ratings only;

functional operation of the device at these or any other condi-

tions greater than those indicated in the operational sections of

this specification is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect device

reliability.

Preliminary Technical Data

ESD SENSITIVITY

ESD (electrostatic discharge) sensitive device.

Charged devices and circuit boards can discharge

without detection. Although this product features

patented or proprietary protection circuitry, damage

may occur on devices subjected to high energy ESD.

Therefore, proper ESD precautions should be taken to

avoid performance degradation or loss of functionality.
