For all VDD* supply inputs, 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. This is required for all supply inputs, but special care should be given to the VDD_CORE, VDD_MCU, and VDD_CPU domains which have higher transient current demand compared to other rails.
Refer to Power-On-Hour (POH) Limits for limitations.
VDDS_DDR is required to still be powered with LPDDR4 voltage ranges, even If DDR interface is unused.
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.
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 Voltage and Thermal Manager section in the device TRM. The power supply should be adjustable over the ranges shown in the VDD_CPU AVS Range entry.
When DDR1 is used concurrently with either OSPI0 or Hyperbus, VDDSHV1_MCU is limited to 1.8V (3.3V mode not supported if DDR1 is used in the system.)
An external resistor divider is required to limit the voltage applied to this device pin. For more information, see USB VBUS Design Guidelines.
