(1) In a typical implementation, the power supply should target the NOM voltage.

(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) For all OPPs, AVS must be enabled to avoid impact on device reliability, lifetime POH (Power-On-Hours), and device power.

(5) The AVS voltages are device-dependent, voltage domain-dependent, and OPP-dependent. They must be read from the

STD_FUSE_OPP. For information about STD_FUSE_OPP Registers address, please refer to Control Module Section of the TRM. The

power supply should be adjustable over the following ranges for each required OPP:

–

OPP_NOM: 0.85V - 1.06V

–

OPP_OD: 0.94V - 1.15V

–

OPP_HIGH: 1.05V - 1.25V

The AVS Voltages will be within the above specified ranges.
