MAXIMUM POWER DISSIPATION
See Engineer-to-Engineer Note “Estimating Power Dissipation
for ADSP-2147x SHARC Processors” for detailed thermal and
power information regarding maximum power dissipation. For
information on package thermal specifications, see Thermal
Characteristics on Page 66.

ability, see Ordering Guide on Page 76.
ESD SENSITIVITY
ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 17 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 Operating Conditions on
Page 21 is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

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.
