AT91SAM9263 Preliminary
6249G–ATARM–06-Jan-09
5.Power Considerations
5.1Power Supplies
AT91SAM9263 has several types of power supply pins:
• VDDCORE pins: Power the core, including the processor, the embedded memories and the
peripherals; voltage ranges from 1.08V to 1.32V, 1.2V nominal.
• VDDIOM0 and VDDIOM1 pins: Power the External Bus Interface 0 I/O lines and the External
Bus Interface 1 I/O lines, respectively; voltage ranges between 1.65V and 1.95V (1.8V
nominal) or between 3.0V and 3.6V (3.3V nominal).
• VDDIOP0 pins: Power the Peripheral I/O lines and the USB transceivers; voltage ranges from
2.7V to 3.6V, 3.3V nominal.
• VDDIOP1 pins: Power the Peripheral I/O lines involving the Image Sensor Interface; voltage
ranges from 1.65V to 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 1.08V to 1.32V, 1.2V nominal.
• VDDPLL pin: Powers the PLL cells; voltage ranges from 3.0V to 3.6V, 3.3V nominal.
• VDDOSC pin: Powers the Main Oscillator cells; voltage ranges from 3.0V to 3.6V, L3.3V
nominal.
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.
AT91SAM9263 Preliminary
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.
5.2Power Consumption
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 system 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).
5.3Programmable I/O Lines Power Supplies
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 30 pF for power
supply at 1.8V and 50pF for power supply at 3.3V. The other signals (control, address and data
signals) do not go over 50MHz.
The voltage ranges are determined by programming registers in the Chip Configuration registers
located in the Matrix User Interface.
6249G–ATARM–06-Jan-09
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
13
the pins is only 1.8V without reprogramming the EBI0 voltage range. The user must be sure to
program the EBI0 voltage range before getting the device out of its Slow Clock Mode.
6.I/O Line Considerations
6.1JTAG 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
(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 JTAG signals except JTAGSEL (VDDBU) are supplied with VDDIOP0.
6.2Test 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.
6.3Reset Pins
6.4PIO Controllers
NRST is 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 manage 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 of 100 kΩ minimum to
VDDIOP0.
The NRST signal is inserted in the Boundary Scan.
All the I/O lines managed by the PIO Controllers integrate a programmable pull-up resistor of
100 kΩ typical. 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 that require to be enabled as Peripheral
at reset. This is explicitly indicated in the column “Reset State” of the PIO Controller multiplexing
tables on page 36 and following.
6.5Shutdown Logic Pins
The SHDN pin is a tri-state output only pin, which is driven by the Shutdown Controller. There is
no internal pull-up. An external pull-up to VDDBU is needed and its value must be higher than 1
14
AT91SAM9263 Preliminary
6249G–ATARM–06-Jan-09
MΩ. The resisitor 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.

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 256M bytes. The banks 1 to
9 are directed to the EBI0 that associates these banks to the external chip selects EBI0_NCS0
to EBI0_NCS5 and EBI1_NCS0 to EBI1_NCS2. The bank 0 is reserved for the addressing of the
internal memories, and a second level of decoding provides 1M bytes 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 for
each 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 and 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.

8.1.1.1Internal 80 Kbyte Fast SRAM
The AT91SAM9263 device embeds a high-speed 80 Kbyte SRAM. This internal SRAM is split
into three areas. Its memory mapping is presented in Figure 8-1 on page 21.

• Internal SRAM A is the ARM926EJ-S Instruction TCM. The user can map this SRAM block
anywhere in the ARM926 instruction memory space using CP15 instructions and the TCR

configuration register located in the Chip Configuration User Interface. This SRAM block is
also accessible by the ARM926 Data Master and by the AHB Masters through the AHB bus
at address 0x0010 0000.
• Internal SRAM B is the ARM926EJ-S Data TCM. The user can map this SRAM block
anywhere in the ARM926 data memory space using CP15 instructions. This SRAM block is
also accessible by the ARM926 Data Master and by the AHB Masters through the AHB bus
at address 0x0020 0000.
• Internal SRAM C is only accessible by all the AHB Masters. After reset and until the Remap
Command is performed, this SRAM block is accessible through the AHB bus at address
0x0030 0000 by all the AHB Masters. After Remap, this SRAM block also becomes
accessible through the AHB bus at address 0x0 by the ARM926 Instruction and the ARM926
Data Masters.
Within the 80 Kbytes of SRAM available, the amount of memory assigned to each block is software programmable as a multiple of 16 Kbytes as shown in Table 8-2. This table provides the
size of the Internal SRAM C according to the size of the internal SRAM A and the internal SRAM
B.

Note that among the five 16 Kbyte blocks making up the Internal SRAM, one is permanently
assigned to Internal SRAM C.
At reset, the whole memory (80 Kbytes) is assigned to Internal SRAM C.
The memory blocks assigned to SRAM A, SRAM B and SRAM C areas are not contiguous and
when the user dynamically changes the Internal SRAM configuration, the new 16 Kbyte block
organization may affect the previous configuration from a software point of view.

When accessed from the Bus Matrix, the internal 80 Kbytes of Fast SRAM is single cycle accessible at full matrix speed (MCK). When accessed from the processor’s TCM Interface, they are
also single cycle accessible at full processor speed.
8.1.1.2Internal 16 Kbyte Fast SRAM
The AT91SAM9263 integrates a 16 Kbyte SRAM, mapped at address 0x0050 0000. This SRAM
is single cycle accessible at full Bus Matrix speed.
8.1.2Boot Strategies
The system always boots at address 0x0. To ensure maximum boot possibilities, the memory
layout can be changed with two parameters.
REMAP allows the user to layout the internal SRAM bank to 0x0. This is done by software once
the system has booted. Refer to the section “AT91SAM9263 Bus Matrix” in the product
datasheet for more details.
When REMAP = 0, BMS allows the user to layout at address 0x0 either 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 21.
The AT91SAM9263 Bus Matrix manages a boot memory that depends on the level on the pin
BMS at reset. The internal memory area mapped between address 0x0 and 0x000F FFFF is
reserved to this effect.
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.
8.1.2.1BMS = 1, Boot on Embedded ROM
The system boots on Boot Program.
• Boot at slow clock

The customer-programmed software must perform a complete configuration.
To speed up the boot sequence when booting at 32 kHz EBI0 CS0 (BMS=0) the user must:
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.

9.System Controller
The System Controller is a set of peripherals that allow handling of key elements of the system,
such as power, resets, clocks, time, interrupts, watchdog, etc.
The System Controller User Interface also embeds registers that are used to configure the Bus
Matrix and a set of registers for the chip configuration. The chip configuration registers can be
used to configure:
The System Controller peripherals are all mapped within the highest 16 Kbytes of address
space, between addresses 0xFFFF C000 and 0xFFFF FFFF.
However, all the registers of the System Controller are mapped on the top of the address space.
This allows all the registers of the System Controller to be addressed from a single pointer by
using the standard ARM instruction set, as the Load/Store instructions have an indexing mode of
± 4 Kbytes.
Figure 9-1 on page 28 shows the System Controller block diagram.
Figure 8-1 on page 21 shows the mapping of the User Interfaces of the System Controller
peripherals.
