5. Power Considerations
5.1 Power Supplies
The SAM9M10 has several types of power supply pins:
z VDDCORE pins: Power the core, including the processor, the embedded memories and the peripherals; voltage
ranges from 0.9V to 1.1V, 1.0V typical.
z VDDIOM0 pins: Power the DDR2/LPDDR I/O lines; voltage ranges between 1.65V and 1.95V (1.8V typical).
z VDDIOM1 pins: Power the External Bus Interface 1 I/O lines; voltage ranges between 1.65V and 1.95V (1.8V
typical) or between 3.0V and 3.6V (3.3V typical).
z VDDIOP0, VDDIOP1, VDDIOP2 pins: Power the Peripherals I/O lines; voltage ranges from 1.65V to 3.6V.
z VDDBU pin: Powers the Slow Clock oscillator, the internal RC oscillator and a part of the System Controller;
voltage ranges from 1.8V to 3.6V.
z VDDPLLUTMI Powers the PLLUTMI cell; voltage range from 0.9V to 1.1V.
z VDDUTMIC pin: Powers the USB device and host UTMI+ core; voltage range from 0.9V to 1.1V, 1.0V typical.
z VDDUTMII pin: Powers the USB device and host UTMI+ interface; voltage range from 3.0V to 3.6V, 3.3V typical.
z VDDPLLA pin: Powers the PLLA cell; voltage ranges from 0.9V to 1.1V.
z VDDOSC pin: Powers the Main Oscillator cells; voltage ranges from 1.65V to 3.6V
z VDDANA pin: Powers the Analog to Digital Converter; voltage ranges from 3.0V to 3.6V, 3.3V typical.
Some supply pins share common ground (GND) pins whereas others have separate grounds.
The respective power/ground pin assignments are as follows:
