5. Power Considerations
5.1 Power Supplies
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.
5.2 Power 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).
14
AT91SAM9260
6221HS–ATARM–31-Jan-08
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.
6. I/O Line Considerations
6.1 JTAG Port Pins
TMS, TDI and TCK are Schmitt trigger inputs and have no pull-up resistors.
AT91SAM9260
6.2 Test Pin
6.3 Reset Pins
TDO and RTCK are outputs, driven at up to VDDIOP0, and have no pull-up resistors.
The JTAGSEL pin is used to select the JTAG boundary scan when asserted at a high level (tied
to VDDBU). It integrates a permanent pull-down resistor of about 15 kΩ to GNDBU, so that it
can be left unconnected for normal operations.
The NTRST signal is described in Section 6.3.
All the JTAG signals are supplied with VDDIOP0.
The TST pin is used for manufacturing test purposes when asserted high. It integrates a permanent pull-down resistor of about 15 kΩ to GNDBU, so that it can be left unconnected for normal
operations. Driving this line at a high level leads to unpredictable results.
This pin is supplied with VDDBU.
NRST is a bidirectional with an open-drain output integrating a non-programmable pull-up resistor. It can be driven with voltage at up to VDDIOP0.
NTRST is an input which allows reset of the JTAG Test Access port. It has no action on the
processor.
As the product integrates power-on reset cells, which manages the processor and the JTAG
reset, the NRST and NTRST pins can be left unconnected.
6221HS–ATARM–31-Jan-08
The NRST and NTRST pins both integrate a permanent pull-up resistor to VDDIOP0. Its value
can be found in the table “DC Characteristics” in the section “AT91SAM9260 Electrical Characteristics” in the product datasheet.
The NRST signal is inserted in the Boundary Scan.
15
6.4 PIO Controllers
All the I/O lines managed by the PIO Controllers integrate a programmable pull-up resistor.
Refer to the section on DC Characteristics in “AT91SAM9260 Electrical Characteristics” for
more information. Programming of this pull-up resistor is performed independently for each I/O
line through the PIO Controllers.
After reset, all the I/O lines default as inputs with pull-up resistors enabled, except those which
are multiplexed with the External Bus Interface signals and that must be enabled as Peripheral
at reset. This is explicitly indicated in the column “Reset State” of the PIO Controller multiplexing
tables.
6.5 I/O Line Drive Levels
The PIO lines are high-drive current capable. Each of these I/O lines can drive up to 16 mA permanently except PC4 to PC31 that are VDDIOM powered.
6.6 Shutdown Logic Pins
The SHDN pin is an output only, which is driven by the Shutdown Controller.
The pin WKUP is an input-only. It can accept voltages only between 0V and VDDBU.
6.7 Slow Clock Selection
The AT91SAM9260 slow clock can be generated either by an external 32,768 Hz crystal or the
on-chip RC oscillator.
Table 6-1 defines the states for OSCSEL signal.
Table 6-1. Slow Clock Selection
OSCSEL Slow Clock Startup Time
0 Internal RC 240 µs
1 External 32768 Hz 1200 ms
The startup counter delay for the slow clock oscillator depends on the OSCSEL signal. The
32,768 Hz startup delay is 1200 ms whereas it is 240 µs for the internal RC oscillator (refer to
Table 6-1). The pin OSCSEL must be tied either to GND or VDDBU for correct operation of the
device.

7.2.2 Matrix Slaves
• Remap Command
– Allows Remapping of an Internal SRAM in Place of the Boot Non-Volatile Memory
– Allows Handling of Dynamic Exception Vectors
The Bus Matrix of the AT91SAM9260 manages six Masters, which means that each master can
perform an access concurrently with others, according the slave it accesses is available.
Each Master has its own decoder that can be defined specifically for each master. In order to
simplify the addressing, all the masters have the same decodings.

Master 0 ARM926™ Instruction
Master 1 ARM926 Data
Master 2 PDC
Master 3 USB Host DMA
Master 4 ISI Controller
Master 5 Ethernet MAC
Each Slave has its own arbiter, thus allowing a different arbitration per Slave to be programmed.

A first level of address decoding is performed by the Bus Matrix, i.e., the implementation of the
Advanced High Performance Bus (AHB) for its Master and Slave interfaces with additional
features.
Decoding breaks up the 4G bytes of address space into 16 banks of 256 Mbytes. The banks 1 to
7 are directed to the EBI that associates these banks to the external chip selects EBI_NCS0 to
EBI_NCS7. Bank 0 is reserved for the addressing of the internal memories, and a second level
of decoding provides 1 Mbyte of internal memory area. Bank 15 is reserved for the peripherals
and provides access to the Advanced Peripheral Bus (APB).
Other areas are unused and performing an access within them provides an abort to the master
requesting such an access.
Each Master has its own bus and its own decoder, thus allowing a different memory mapping
per Master. However, in order to simplify the mappings, all the masters have a similar address
decoding.
Regarding Master 0 and Master 1 (ARM926 Instruction and Data), three different Slaves are
assigned to the memory space decoded at address 0x0: one for internal boot, one for external
boot, one after remap. Refer to Table 8-1, “Internal Memory Mapping,” on page 22 for details.
A complete memory map is presented in Figure 8-1 on page 21.
8.1 Embedded Memories
• 32 KB ROM
– Single Cycle Access at full matrix speed
• Two 4 KB Fast SRAM
– Single Cycle Access at full matrix speed
8.1.1 Boot Strategies
Table 8-1 summarizes the Internal Memory Mapping for each Master, depending on the Remap
status and the BMS state at reset.
Table 8-1. Internal Memory Mapping
Address
0x0000 0000 ROM EBI_NCS0 SRAM0 4K
The system always boots at address 0x0. To ensure a maximum number of possibilities for boot,
the memory layout can be configured with two parameters.
REMAP allows the user to lay out the first internal SRAM bank to 0x0 to ease development. This
is done by software once the system has booted. Refer to the Bus Matrix Section for more
details.
When REMAP = 0, BMS allows the user to lay out to 0x0, at his convenience, the ROM or an
external memory. This is done via hardware at reset.
Note: Memory blocks not affected by these parameters can always be seen at their specified base
addresses. See the complete memory map presented in
REMAP = 0 REMAP = 1
BMS = 1 BMS = 0
Figure 8-1 on page 21.

AT91SAM9260
6221HS–ATARM–31-Jan-08
The AT91SAM9260 matrix manages a boot memory that depends on the level on the BMS pin
at reset. The internal memory area mapped between address 0x0 and 0x000F FFFF is reserved
for this purpose.
If BMS is detected at 1, the boot memory is the embedded ROM.
If BMS is detected at 0, the boot memory is the memory connected on the Chip Select 0 of the
External Bus Interface.
8.1.1.1 BMS = 1, Boot on Embedded ROM
The system boots using the Boot Program.

AT91SAM9260
8.1.1.2 BMS = 0, Boot on External Memory
• Boot on slow clock (On-chip RC or 32,768 Hz)
• Boot with the default configuration for the Static Memory Controller, byte select mode, 16-bit
data bus, Read/Write controlled by Chip Select, allows boot on 16-bit non-volatile memory.
The customer-programmed software must perform a complete configuration.
To speed up the boot sequence when booting at 32 kHz EBI CS0 (BMS=0), the user must take
the following steps:
1. Program the PMC (main oscillator enable or bypass mode).
2. Program and start the PLL.
3. Reprogram the SMC setup, cycle, hold, mode timings registers for CS0 to adapt them
to the new clock.
4. Switch the main clock to the new value.
8.2 External Memories
The external memories are accessed through the External Bus Interface. Each Chip Select line
has a 256-Mbyte memory area assigned.

9. System Controller
The System Controller is a set of peripherals that allows handling of key elements of the system,
such as power, resets, clocks, time, interrupts, watchdog, etc.
The System Controller User Interface also embeds the registers that configure the Matrix and a
set of registers for the chip configuration. The chip configuration registers configure EBI chip
select assignment and voltage range for external memories
The System Controller’s peripherals are all mapped within the highest 16 Kbytes of address
space, between addresses 0xFFFF E800 and 0xFFFF FFFF.
However, all the registers of System Controller are mapped on the top of the address space. All
the registers of the System Controller can be addressed from a single pointer by using the standard ARM instruction set, as the Load/Store instruction has an indexing mode of ±4 Kbytes.
Figure 9-1 on page 27 shows the System Controller block diagram.
Figure 8-1 on page 21 shows the mapping of the User Interfaces of the System Controller
peripherals.

10. Peripherals
10.1 User Interface
10.2 Identifiers
The peripherals are mapped in the upper 256 Mbytes of the address space between the
addresses 0xFFFA 0000 and 0xFFFC FFFF. Each User Peripheral is allocated 16 Kbytes of
address space. A complete memory map is presented in Figure 8-1 on page 21.
Table 10-1 defines the Peripheral Identifiers of the AT91SAM9260. A peripheral identifier is
required for the control of the peripheral interrupt with the Advanced Interrupt Controller and for
the control of the peripheral clock with the Power Management Controller.

30 AIC Advanced Interrupt Controller IRQ1
31 AIC Advanced Interrupt Controller IRQ2
Note: Setting AIC, SYSC, UHP, ADC and IRQ0-2 bits in the clock set/clear registers of the PMC has no effect. The ADC clock is auto-
matically started for the first conversion. In Sleep Mode the ADC clock is automatically stopped after each conversion.
10.2.1 Peripheral Interrupts and Clock Control
10.2.1.1 System Interrupt
The System Interrupt in Source 1 is the wired-OR of the interrupt signals coming from:
• the SDRAM Controller
• the Debug Unit
• the Periodic Interval Timer
• the Real-time Timer
• the Watchdog Timer
• the Reset Controller
• the Power Management Controller
The clock of these peripherals cannot be deactivated and Peripheral ID 1 can only be used
within the Advanced Interrupt Controller.
10.2.1.2 External Interrupts
All external interrupt signals, i.e., the Fast Interrupt signal FIQ or the Interrupt signals IRQ0 to
IRQ2, use a dedicated Peripheral ID. However, there is no clock control associated with these
peripheral IDs.
10.3 Peripheral Signal Multiplexing on I/O Lines
The AT91SAM9260 features 3 PIO controllers (PIOA, PIOB, PIOC) that multiplex the I/O lines of
the peripheral set.
Each PIO Controller controls up to 32 lines. Each line can be assigned to one of two peripheral
functions, A or B. Table 10-2 on page 34, Table 10-3 on page 35 and Table 10-4 on page 36
define how the I/O lines of the peripherals A and B are multiplexed on the PIO Controllers. The
two columns “Function” and “Comments” have been inserted in this table for the user’s own
comments; they may be used to track how pins are defined in an application.
Note that some peripheral functions which are output only might be duplicated within both
tables.
The column “Reset State” indicates whether the PIO Line resets in I/O mode or in peripheral
mode. If I/O appears, the PIO Line resets in input with the pull-up enabled, so that the device is
maintained in a static state as soon as the reset is released. As a result, the bit corresponding to
the PIO Line in the register PIO_PSR (Peripheral Status Register) resets low.
If a signal name appears in the “Reset State” column, the PIO Line is assigned to this function
and the corresponding bit in PIO_PSR resets high. This is the case of pins controlling memories,
in particular the address lines, which require the pin to be driven as soon as the reset is
released. Note that the pull-up resistor is also enabled in this case.

The USART contains features allowing management of the Modem Signals DTR, DSR, DCD
and RI. In the AT91SAM9260, only the USART0 implements these signals, named DTR0,
DSR0, DCD0 and RI0.
The USART1 and USART2 do not implement all the modem signals. Only RTS and CTS (RTS1
and CTS1, RTS2 and CTS2, respectively) are implemented in these USARTs for other features.
Thus, programming the USART1, USART2 or the USART3 in Modem Mode may lead to unpredictable results. In these USARTs, the commands relating to the Modem Mode have no effect
and the status bits relating the status of the modem signals are never activated.
