(1)

The voltage at the device ball must 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, and so forth.

(2)

Refer to Power-On-Hour (POH) Limits for limitations.

(3)

This value is without AVS. The AVS Voltages are device-dependent, voltage domain-dependent, and OPP-dependent. They must be

read from the VTM_DEVINFO_VDn. For information about VTM_DEVINFO_VDn registers address, please refer to section Voltage

and Thermal Manager (VTM) in the device TRM. The power supply should be adjustable over the following ranges for each required

OPP:

•

OPP_NOM: 0.9 V – 1.1 V

•

OPP_OD: 0.9 V – 1.2 V

•

OPP_TURBO: 0.9 V – 1.24 V

The AVS Voltages will be within the above specified ranges.

(4)

VDDS_DDR is required to still be powered with either DDR4 voltage ranges, even If DDR interface is unused.

(5)

This terminal is connected to analog circuits in the respective USB PHY. The circuit sources a known current while measuring the

voltage to determine if the terminal is connected to VSS with a resistance less than 10 Ω or greater than 100 kΩ. The terminal should

be connected to ground for USB host operation or open-circuit for USB peripheral operation, and should never be connected to any

external voltage source.

(6)

The VDDA_VSYS_MON pin provides a way to monitor the system power supply and is not fail-safe, unless implemented with the

appropriate resistor voltage divider source. For more information, see Section 9.2.5, System Power Supply Monitor Design Guidelines.

(7)

An external resistor divider is required to limit the voltage applied to this device pin. For more information, see Section 9.2.3, USB

Design Guidelines.
