To prevent high current conditions due to possible improper sequencing of the power supplies, the
connection shown below is recommended to be made between the DSP56374 IO_VDD and Core_VDD
power pins.

Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed.
Operating temperature qualified for automotive applications. T
If the power supply ramp to full supply time is longer than 10 ms, the POR circuitry will not operate correctly,
Stress beyond the maximum rating may affect device reliability or cause permanent damage to the device.

causing erroneous operation.
Power Requirements
In the calculation of timing requirements, adding a maximum value of one
specification to a minimum value of another specification does not yield a
reasonable sum. A maximum specification is calculated using a worst case variation
of process parameter values in one direction. The minimum specification is
calculated using the worst case for the same parameters in the opposite direction.
Therefore, a “maximum” value for a specification will never occur in the same
device that has a “minimum” value for another specification; adding a maximum to
a minimum represents a condition that can never exist.
