(1) Refer to Power on Hours table Table 5-3 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) If DDR2 type of memories are used, the EMIF power supply (vdds_ddrx) and the corresponding bias power supply (vdds18v_ddrx) must

be sourced from single power source.

(5) The TSHUT feature of the SoC resets the device by default when one of the on-die temp sensors reports 123°C. This is intended to

protect the device from exceeding 125°C. Though not recommended, the TSHUT temperature threshold can be modified in software if

other mechanisms are in place to avoid exceeding 125°C. Refer to the device TRM for details on the TSHUT feature.
