Power Considerations
5.1
Power Supplies
The SAM3X/A series product has several types of power supply pins:
VDDCORE pins: Power the core, the embedded memories and the peripherals; voltage
ranges from 1.62V to 1.95V.
VDDIO pins: Power the Peripherals I/O lines; voltage ranges from 1.62V to 3.6V.
VDDIN pin: Powers the Voltage regulator
VDDOUT pin: It is the output of the voltage regulator.
VDDBU pin: Powers the Slow Clock oscillator and a part of the System Controller; voltage
ranges from 1.62V to 3.6V. VDDBU must be supplied before or at the same time than VDDIO
and VDDCORE.
VDDPLL pin: Powers the PLL A, UPLL and 3-20 MHz Oscillator; voltage ranges from 1.62V
to 1.95V.
VDDUTMI pin: Powers the UTMI+ interface; voltage ranges from 3.0V to 3.6V, 3.3V nominal.
VDDANA pin: Powers the ADC and DAC cells; voltage ranges from 2.0V to 3.6V.
Ground pins GND are common to VDDCORE and VDDIO pins power supplies.
Separated ground pins are provided for VDDBU, VDDPLL, VDDUTMI and VDDANA. These
ground pins are respectively GNDBU, GNDPLL, GNDUTMI and GNDANA.
5.2
Voltage Regulator
The SAM3X/A series embeds a voltage regulator that is managed by the Supply Controller.
This internal regulator is intended to supply the internal core of SAM3X/A series but can be used
to supply other parts in the application. It features two different operating modes:
In Normal mode, the voltage regulator consumes less than 700 A static current and draws
150 mA of output current. Internal adaptive biasing adjusts the regulator quiescent current
depending on the required load current. In Wait Mode or when the output current is low,
quiescent current is only 7A.
In Shutdown mode, the voltage regulator consumes less than 1 A while its output is driven
internally to GND. The default output voltage is 1.80V and the start-up time to reach Normal
mode is inferior to 400 s.
For adequate input and output power supply decoupling/bypassing, refer to “Voltage Regulator”
in the “Electrical Characteristics” section of the product datasheet.
