Power Supplies
Power Supply Connections
The AT32AP7002 has several types of power supply pins:
•
•
•
•
•
The ground pins GND are common to VDDCORE and VDDIO. The ground pin for VDDPLL is
GNDPLL, and the GND pin for VDDOSC is GNDOSC.
See
Special considerations should be made when connecting the power and ground pins on a PCB.

VDDCORE pins: Power the core, memories, and peripherals. Voltage is 1.8V nominal.
VDDIO pins: Power I/O lines. Voltage is 3.3V nominal.
VDDPLL pin: Powers the PLL. Voltage is 1.8V nominal.
VDDUSB pin: Powers the USB. Voltage is 1.8V nominal.
VDDOSC pin: Powers the oscillators. Voltage is 1.8V nominal.
