*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions above 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
The ADSP-217x is an ESD (electrostatic discharge) sensitive device. Electrostatic charges readily
accumulate on the human body and equipment and can discharge without detection. Permanent
damage may occur to devices subjected to high energy electrostatic discharges.
The ADSP-217x features proprietary ESD protection circuitry to dissipate high energy discharges
(Human Body Model). Per method 3015 of MIL-STD-883, the ADSP-217x has been classified as
a Class 1 device.
Proper ESD precautions are recommended to avoid performance degradation or loss of function-
ality. Unused devices must be stored in conductive foam or shunts, and the foam should be
discharged to the destination before devices are removed.
WARNING!

GENERAL NOTES
Use the exact timing information given. Do not attempt to de-
rive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results for
an individual device, the values given in this data sheet reflect
statistical variations and worst cases. Consequently, you cannot
meaningfully add up parameters to derive longer times.
TIMING NOTES
Switching characteristics specify how the processor changes its
signals. You have no control over this timing; it is dependent on
the internal design. Timing requirements apply to signals that
are controlled outside the processor, such as the data input for a
read operation.
Timing requirements guarantee that the processor operates cor-
rectly with another device. Switching characteristics tell you
what the device will do under a given circumstance. Also, use
the switching characteristics to ensure any timing requirement
of a device connected to the processor (such as memory) is
satisfied.
