Power Supply Considerations
The AT91SAM9R64/RL64 has several types of power supply pins:
The power supplies VDDIOM and VDDIOP are identified in the pinout table and the PIO multi-
plexing tables. These supplies enable the user to power the device differently for interfacing with
memories and for interfacing with peripherals.
Ground pins GND are common to VDDCORE, VDDIOM and VDDIOP pins power supplies.
Separated ground pins are provided for VDDBU, VDDPLLA, VDDPLLB and VDDANA. These
ground pins are respectively GNDBU, GNDPLLA, GNDPLLB and GNDANA. A common ground
pin is provided for VDDUTMII and VDDUTMIC. This ground pin is GNDUTMI.
Caution: VDDCORE and VDDIO constraints at startup to be checked in the Core Power Supply
POR Characteristics in the Electical Characteristics section of the datasheet.
To achieve the best performances on the UDPHS, care must be taken in the power supplies
choice and especially on VDDPLLB,VDDUTMIC and VDDUTMII.
The USB High speed requires power supplies with a ripple voltage < 20 mV on VDDPLLB and
VDDUTMIC. The VDDUTMII powering the UTMI transceiver must also be filtered.
It is highly recommended to use an LDO linear regulator to generate the 1.2 volts for both
VDDPLLB and VDDUTMIC. VDDUTMII can be connected on the 3.3 volts of the system via an
LC filter.
The figure below gives an example of VDDPLLB, VDDUTMIC and VDDUTMII.
• VDDCORE pins: Power the core, including the processor, the embedded memories and the
• VDDIOM pins: Power the External Bus Interface; voltage ranges between 1.65V and 1.95V
• VDDIOP pins: Power the Peripherals I/O lines; voltage ranges from 3.0V and 3.6V, 3.3V
• VDDBU pin: Powers the Slow Clock oscillator and a part of the System Controller; voltage
• VDDPLLA pin: Powers the PLL cell; voltage ranges from 3.0V and 3.6V, 3.3V nominal.
• VDDPLLB pin: Powers the UTMI PLL (480MHz) and OSC 12M cells; voltage ranges from
• VDDUTMII pin: Powers the UTMI+ interface; voltage ranges from 3.0V and 3.6V, 3.3V
• VDDUTMIC pin: Powers the UTMI+ core; voltage ranges from 1.08V and 1.32V, 1.2V
• VDDANA pin: Powers the ADC cell; voltage ranges from 3.0V and 3.6V, 3.3V nominal.
