Power Considerations
6.1
Power Supplies
The AT32UC3A has several types of power supply pins:
VDDIO: Powers I/O lines. Voltage is 3.3V nominal.
VDDANA: Powers the ADC Voltage is 3.3V nominal.
VDDIN: Input voltage for the voltage regulator. Voltage is 3.3V nominal.
VDDCORE: Powers the core, memories, and peripherals. Voltage is 1.8V nominal.
VDDPLL: Powers the PLL. Voltage is 1.8V nominal.
The ground pins GND are common to VDDCORE, VDDIO, VDDPLL. The ground pin for
VDDANA is GNDANA.
Refer to ”P(pán)ower Consumption” on page 767 for power consumption on the various supply pins.
