3.2.1 Power Supply

The PMIC (main regulator) provides all power supplies required by the SAM9X75D2G device:

  • 1.15V for VDDCORE
  • 1.35V for VDDIODDR
  • 3.3V for VDD3V3

A 1.8V backup supply is also available for VDDBU.

Decoupling capacitors are placed close to the MPU power pins to stabilize the voltage rails.

The following figure shows the processor power supplies.
