AT91SAM9260
6221HS–ATARM–31-Jan-08
1.Description
The AT91SAM9260 is based on the integration of an ARM926EJ-S processor with fast ROM
and RAM memories and a wide range of peripherals.
The AT91SAM9260 embeds an Ethernet MAC, one USB Device Port, and a USB Host controller. It also integrates several standard peripherals, such as the USART, SPI, TWI, Timer
Counters, Synchronous Serial Controller, ADC and MultiMedia Card Interface.
The AT91SAM9260 is architectured on a 6-layer matrix, allowing a maximum internal bandwidth
of six 32-bit buses. It also features an External Bus Interface capable of interfacing with a wide
range of memory devices.

The AT91SAM9260 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.
5.2Power Consumption
The AT91SAM9260 consumes about 500 µA 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 µA in worst case conditions.
For dynamic power consumption, the AT91SAM9260 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).
