5.1 Power Supplies
The AT91CAP9S500A/AT91CAP9S250A has several types of power supply pins:
• VDDCORE pins: Power the core, including the processor, the embedded memories and the
peripherals; voltage range between1.08V and 1.32V, 1.2V nominal.
• VDDIOM pins: Power the External Bus Interface; voltage ranges between 1.65V and 1.95V
(1.8V nominal) or between 3.0V and 3.6V (3.3V nominal).
• VDDIOP0 pins: Power the Peripherals I/O lines and the USB transceivers; voltage range
between 3.0V and 3.6V, 3.3V nominal.
• VDDIOP1 pins: Power the Peripherals I/O lines involving the Image Sensor Interface; voltage
ranges from 1.65V to 3.6V, 1.8V, 2.5V, 3V or 3.3V nominal.
