Power Considerations
3.1
Power Supplies
The AT32AP7001 has several types of power supply pins:
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.
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 ”Electrical Characteristics” on page 796 for power consumption on the various supply pins.

Power Supply Connections
Special considerations should be made when connecting the power and ground pins on a PCB.
Figure 3-1 shows how this should be done.
