(1) Refer to Power on Hours table for limitations.
(2) The voltage at the device ball should never be below the MIN voltage or above the MAX voltage for any amount of time. This
requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, etc.
(3) The DC voltage at the device ball should never be above the MAX DC voltage to avoid impact on device reliability and lifetime POH
(Power-On-Hours). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.
(4) Logic functions and parameter values are not assured out of the range specified in the recommended operating conditions.
5.5 Operating Performance Points
This section describes the operating conditions of the device. This section also contains the description of
each OPP (operating performance point) for processor clocks and device core clocks.
CAUTION
The OPP voltage and frequency values may change following the silicon
characterization result.
Table 5-1 describes the maximum supported frequency per speed grade for DRA79x devices.
