Description
The SAM9260 is based on the integration of an ARM926EJ-S processor with fast ROM and RAM memories and a wide
range of peripherals.
The SAM9260 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 SAM9260 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.

Power Considerations
5.1
Power Supplies
The SAM9260 has several types of power supply pins:
z
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.
z
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.
z
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.
z
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.
z
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.
z
VDDPLL pin: Powers the Main Oscillator and PLL cells; voltage ranges from 1.65V and 1.95V, 1.8V nominal.
z
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 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 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.

I/O Line Considerations
6.1
JTAG Port Pins
TMS, TDI and TCK are Schmitt trigger inputs and have no pull-up resistors.
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.
6.2
Test Pin
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.
6.3
Reset Pins
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.
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 “SAM9260 Electrical Characteristics” in the product datasheet.
The NRST signal is inserted in the Boundary Scan.
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 “SAM9260 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 a tri-state output pin, which is driven by the Shutdown Controller. There is no internal pull-up. An
external pull-up tied to VDDBU is needed and its value must be higher than 1 MΩ. The resistor value is calculated
according to the regulator enable implementation and the SHDN level.
The pin WKUP is an input-only. It can accept voltages only between 0V and VDDBU.

6.7
Slow Clock Selection
The SAM9260 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.

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.

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.

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 20 for details.
A complete memory map is presented in Figure 8-1 on page 19.

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 Figure 8-1 on page 19.
The SAM9260 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.

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:
8.2
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.
External Memories

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 24 shows the System Controller block diagram.
Figure 8-1 on page 19 shows the mapping of the User Interfaces of the System Controller peripherals.

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:
z
the SDRAM Controller
z
the Debug Unit
z
the Periodic Interval Timer
z
the Real-time Timer
z
the Watchdog Timer
z
the Reset Controller
z
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 SAM9260 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 31, Table 10-3 on page 32 and Table 10-4 on page 33 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 SAM9260,
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.
