SAM9260 [SUMMARY]
6221LS–ATARM–15-Oct-12
5.
Power Considerations
5.1
Power Supplies
The SAM9260 has several types of power supply pins:
VDDCORE pins: Power the core, including the processor, the embedded memories and the peripherals; voltage
ranges from 1.65V and 1.95V, 1.8V nominal.
VDDIOM pins: Power the External Bus Interface I/O lines; voltage ranges between 1.65V and 1.95V (1.8V typical)
or between 3.0V and 3.6V (3.3V nominal). The expected voltage range is selectable by software.
VDDIOP0 pins: Power the Peripheral I/O lines and the USB transceivers; voltage ranges from 3.0V and 3.6V, 3V
or 3.3V nominal.
VDDIOP1 pins: Power the Peripherals I/O lines involving the Image Sensor Interface; voltage ranges from 1.65V
and 3.6V, 1.8V, 2.5V, 3V or 3.3V nominal.
VDDBU pin: Powers the Slow Clock oscillator and a part of the System Controller; voltage ranges from 1.65V to
1.95V, 1.8V nominal.
VDDPLL pin: Powers the Main Oscillator and PLL cells; voltage ranges from 1.65V and 1.95V, 1.8V nominal.
VDDANA pin: Powers the Analog to Digital Converter; voltage ranges from 3.0V and 3.6V, 3.3V nominal.
The power supplies VDDIOM, VDDIOP0 and VDDIOP1 are identified in the pinout table and the multiplexing 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, VDDIOP0 and VDDIOP1 pins power supplies. Separated
ground pins are provided for VDDBU, VDDPLL and VDDANA. These ground pins are respectively GNDBU, GNDPLL
and GNDANA.
5.2
Power Consumption
The SAM9260 consumes about 500 A of static current on VDDCORE at 25°C. This static current rises up to 5 mA if the
temperature increases to 85°C.
On VDDBU, the current does not exceed 10 A in worst case conditions.
For dynamic power consumption, the SAM9260 consumes a maximum of 100 mA on VDDCORE at maximum conditions
(1.8V, 25°C, processor running full-performance algorithm out of high speed memories).
5.3
Programmable I/O Lines Power Supplies
The power supplies pins VDDIOM accept two voltage ranges. This allows the device to reach its maximum speed either
out of 1.8V or 3.3V external memories.
The target maximum speed is 100 MHz on the pin SDCK (SDRAM Clock) loaded with 30 pF for power supply at 1.8V and
50 pF for power supply at 3.3V. The other signals (control, address and data signals) do not exceed 50 MHz.
The voltage ranges are determined by programming registers in the Chip Configuration registers located in the Matrix
User Interface.
At reset, the selected voltage defaults to 3.3V nominal, and power supply pins can accept either 1.8V or 3.3V. Obviously,
the device cannot reach its maximum speed if the voltage supplied to the pins is 1.8V only. The user must program the
EBI voltage range before getting the device out of its Slow Clock Mode.
