Power Supplies
Power Consumption
Programmable I/O Lines Power Supplies
AT91SAM9263 has several types of power supply pins:
The power supplies VDDIOM0, VDDIOM1 and VDDIOP0, 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 VDDOSC, VDDCORE, VDDIOM0, VDDIOM1, VDDIOP0 and
VDDIOP1 pins power supplies. Separated ground pins are provided for VDDBU and VDDPLL.
These ground pins are respectively GNDBU and GNDPLL.
The AT91SAM9263 consumes about 700 µA (worst case) of static current on VDDCORE at
25°C. This static current rises at up to 7 mA if the temperature increases to 85°C.
On VDDBU, the current does not exceed 3 µA @25°C, but can rise at up to 20 µA @85°C. An
automatic switch to VDDCORE guarantees low power consumption on the battery when the sys-
tem is on.
For dynamic power consumption, the AT91SAM9263 consumes a maximum of 70 mA on
VDDCORE at maximum conditions (1.2V, 25°C, processor running full-performance algorithm).
The power supply pins VDDIOM0 and VDDIOM1 accept two voltage ranges. This allows the
device to reach its maximum speed, either out of 1.8V or 3.0V external memories.
The maximum speed is 100 MHz on the pin SDCK (SDRAM Clock) loaded with 10 pF. The other
signals (control, address and data signals) do not go over 50 MHz, loaded with 30 pF for power
supply at 1.8V and 50 pF for power supply at 3.3V.
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. However, the device cannot reach its maximum speed if the voltage supplied to
