(1) Refer to Section 5.3, Power on Hour (POH) Limits 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 Hour). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.

Operating Performance Points

This section describes the operating conditions of the AM572x device. This section also contains the

description of each OPP (operating performance point) for processor clocks and device core clocks.

Table 5-5 describes the maximum supported frequency per speed grade for AM572x devices.
