Generated Internally or applied externally.
Voltage at the package power supply contact must be maintained between the minimum and maximum voltages. The design
must allow for supply tolerances and system voltage drops.
The nominal values for the supplies indicate the target setpoint for a tolerance no tighter than ± 50 mV. Use of supplies with
a tighter tolerance allows reduction of the setpoint with commensurate power savings.
USB_OTG_VDDA25 and USB_H1_VDDA25 are shorted together on the 416MAPBGA package substrate.
USB_OTG_VDDA33 and USB_H1_VDDA33 are shorted together on the 416MAPBGA package substrate.
