ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 16 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.
ESD SENSITIVITY
MAXIMUM POWER DISSIPATION
See Engineer-to-Engineer Note “Estimating Power Dissipation
for ADSP-214xx SHARC Processors” (EE-348) for detailed ther-
mal and power information regarding maximum power
dissipation. For information on package thermal specifications,

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.
