ESD SENSITIVITY
TIMING SPECIFICATIONS
This section contains timing information for the DSP external
signals. Use the exact information given. Do not attempt to derive
parameters from the addition or subtraction of other information.
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, parameters
cannot be added meaningfully to derive longer times.
Switching characteristics
specify how the processor changes its
signals. No control is possible over this timing; circuitry external
to the processor must be designed for compatibility with these
signal characteristics. Switching characteristics indicate what the
processor will do in a given circumstance. Switching character-
istics can also be used to ensure that any timing requirement of
a device connected to the processor (such as memory) is satisfied.
Timing requirements
apply to signals that are controlled by
circuitry external to the processor, such as the data input for a
read operation.Timing requirements guarantee that the
processor operates correctly with other devices.
1
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 specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
2
Except CLKIN and analog pins.
CAUTION
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-21991 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.
