ABSOLUTE MAXIMUM RATINGS
ESD CAUTION
TIMING SPECIFICATIONS
This next section contains timing information for the external
signals of the DSP. 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. Con-
sequently, parameters cannot be added meaningfully to derive
longer times.
Timing requirements apply to signals that are controlled by cir-
cuitry external to the processor, such as the data input for a read
operation. Timing requirements guarantee that the processor
operates correctly with other devices.
Switching characteristics specify how the processor changes its
signals. No control is possible over this timing; circuitry exter-
nal 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
characteristics can also be used to ensure that any timing
requirement of a device connected to the processor (such as
memory) is satisfied.

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.
ESD (electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary 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.
