3.2.1 Power Supply

The PMIC (main regulator) provides all power supplies required by the SAM9X60D1G device:

  • 1.15V for VDDCORE
  • 1.8V for VDDIOM
  • 3.3V for VDDIOP0, VDDIOP1, VDDIOQSPI, VDDUTMII, VDDPLLA, VDDANA, VDDOSC, VDDNF and VDDBU

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