(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 Hour). 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 Hour), 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 Registers in the Control Module Section of the TRM. The power supply should be adjustable over the following ranges

for each required OPP:

–

OPP_NOM for MPU: 0.85 V – 1.10 V

–

OPP_NOM for CORE and Others: 0.85 V - 1.06 V

–

OPP_OD: 0.885 V - 1.15 V

–

OPP_HIGH: 0.95 V - 1.25 V

The AVS voltages will be within the above specified ranges.

(6) VD_RTC can optionally be tied to to VD_CORE and operate at the VD_CORE AVS voltages.

Table 5-8 describes the standard processor clocks speed characteristics vs OPP of the device.
