NC pins must be left unconnected. 5. Power Considerations 5.1 Power 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. 12 AT91SAM9263 Preliminary 6249BS–ATARM–18-Dec-06 AT91SAM9263 Preliminary • 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. 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. 5.2 Power Consumption The AT91SAM9263 consumes about 700 µA 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. A software-controllable switch to VDDCORE guarantees zero 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). 5.3 Programmable 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. 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 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 6.1 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 (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. 13 6249BS–ATARM–18-Dec-06 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 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. 6.4 PIO Controllers All the I/O lines managed by the PIO Controllers integrate a programmable pull-up resistor of 100 kΩ minimum. 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 34 and following. 6.5 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. 7.

Each slave has its own arbiter, thus allowing to program a different arbitration per slave. The LCD Controller, the DMA Controller, the USB OTG and the USB Host have a user interface mapped as a slave on the Matrix. They share the same layer, as programming them does not require a high bandwidth. Table 7-2.

However, some paths do not make sense, for example, allowing access from the Ethernet MAC to the Internal Peripherals.

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 21 for details. A complete memory map is presented in Figure 8-1 on page 20. 8.1 Embedded Memories • 128 Kbyte ROM – Single Cycle Access at full matrix speed • One 80 Kbyte Fast SRAM – Single Cycle Access at full matrix speed – Supports ARM926EJ-S TCM interface at full processor speed – Allows internal Frame Buffer for up to 1/4 VGA 8 bpp screen • 16 Kbyte Fast SRAM – Single Cycle Access at full matrix speed 8.1.1 Internal Memory Mapping Table 8-1 summarizes the Internal Memory Mapping, depending on the Remap status and the BMS state at reset. Table 8-1. Internal Memory Mapping REMAP = 0 Address 0x0000 0000 BMS = 1 ROM BMS = 0 EBI_NCS0 SRAM C REMAP = 1 8.1.1.1 Internal 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 20. • 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 21 6249BS–ATARM–18-Dec-06 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. Table 8-2. Internal SRAM Block Size Internal SRAM A (ITCM) Size Internal SRAM C Internal SRAM B (DTCM) size 0 16 Kbytes 32 Kbytes 0 80 Kbytes 64 Kbytes 48 Kbytes 16 Kbytes 64 Kbytes 48 Kbytes 32 Kbytes 32 Kbytes 48 Kbytes 32 Kbytes 16 Kbytes 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. Table 8-3 illustrates different configurations and the related 16 Kbyte blocks assignments (RB0 to RB4).

Configuration after reset. 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. 8.1.1.2 Internal 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. Boot Strategies The system always boot 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. When REMAP = 1, BMS is ignored. 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 20. 8.1.2 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. 8.1.2.1 BMS = 1, Boot on Embedded ROM The system boots on Boot Program. • Boot at slow clock • Auto baudrate detection • Downloads and runs an application from external storage media into internal SRAM • Downloaded code size depends on embedded SRAM size • Automatic detection of valid application • Bootloader on a non-volatile memory 23 6249BS–ATARM–18-Dec-06 – SPI DataFlash® connected on NPCS0 of the SPI0 • Interface with SAM-BA™ Graphic User Interface to enable code loading via: – Serial communication on a DBGU – USB Bulk Device Port 8.1.2.2 BMS = 0, Boot on External Memory • Boot at slow clock • 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 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. 8.2 External Memories The external memories are accessed through the External Bus Interfaces 0 and 1. Each Chip Select line has a 256 Mbyte memory area assigned. Refer to Figure 8-1 on page 20. 8.2.1 External Bus Interfaces The AT91SAM9263 features two External Bus Interfaces to offer more bandwidth to the system and to prevent bottlenecks while accessing external memories.

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: – EBI0 and EBI1 chip select assignment and voltage range for external memories – ARM Processor Tightly Coupled Memories 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.

Peripherals 10.1 User Interface 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 20. 10.2 Identifiers Table 10-1 defines the Peripheral Identifiers. 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.

However, there is no clock control associated with these peripheral IDs. Timer Counter Interrupts The three Timer Counter channels interrupt signals are OR-wired together to provide the interrupt source 19 of the Advanced Interrupt Controller. This forces the programmer to read all Timer Counter status registers before branching the right Interrupt Service Routine. The Timer Counter channels clocks cannot be deactivated independently. Switching off the clock of the Peripheral 19 disables the clock of the 3 channels. 10.2.1.3 10.3 Peripherals Signals Multiplexing on I/O Lines The AT91SAM9263 device features 5 PIO controllers, PIOA, PIOB, PIOC, PIOD and PIOE, which 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. The multiplexing tables 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 may 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 is specified, 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 is specified 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. 33 6249BS–ATARM–18-Dec-06 10.3.1 PIO Controller A Multiplexing Multiplexing on PIO Controller A PIO Controller A Application Usage Reset State I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O PCK0 IRQ0 IRQ1 EBI1_D16 EBI1_D17 EBI1_D18 EBI1_D19 EBI1_D20 EBI1_D21 EBI1_D22 EBI1_D23 EBI1_D24 EBI1_D25 EBI1_D26 EBI1_D27 EBI1_D28 EBI1_D29 EBI1_D30 EBI1_D31 I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O Power Supply VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOP0 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 VDDIOM1 Function Comments Table 10-2.

It supports 4 bits per pixel (bpp), 8 bpp or 16 bpp without limitation. Interfacing 24 bpp TFT panels prevents using the Ethernet MAC. 16 bpp TFT panels are interfaced through peripheral B functions, as color data is output on LCDD3 to LCDD7, LCDD11 to LCDD15 and LCDD19 to LCDD23. Intensity bit is output on LCDD10. Using the peripheral B does not prevent using MAC lines. 16 bpp STN panels are interfaced through peripheral A and color data is output on LCDD0 to LCDD15, thus MAC lines can be used on peripheral B. Mapping the LCD signals on peripheral A and peripheral B makes is possible to use 24 bpp TFT panels in 24 bits (peripheral A) or 16 bits (peripheral B) by reprogramming the PIO controller and thus without hardware modification. 10.4.2 ETM™ Using the ETM prevents the use of the EBI0 in 32-bit mode. Only 16-bit mode (EBI0_D0 to EBI0_D15) is available, makes EBI0 unable to interface CompactFlash and NandFlash cards, reduces EBI0’s address bus width which makes it unable to address memory ranges bigger than 0x7FFFFF and finally it makes impossible to use EBI0_NCS2. 10.4.3 EBI1 Using the following features prevents using EBI1 in 32-bit mode: • the second slots of MCI0 and/or MCI1 • USART0 • DMA request 0 (DMARQ0) 10.4.4 SSC Using SSC0 prevents using the AC97 Controller and Two-wire Interface. Using SSC1 prevents using DMA Request 1, PWM0, PWM1, LCDCC and PCK1. 10.4.5 USART Using USART2 prevents using EBI0’s NWAIT signal, Chip Select 4 and CompactFlash Chip Enable 2. Using USART1 prevents using EBI0’s Chip Select 5 and CompactFlash Chip Enable1. 10.4.6 NAND Flash Using the NAND Flash interface prevents using NCS3, NCS6 and NCS7 to access other parallel devices. 10.4.7 CompactFlash Using the CompactFlash interface prevents using NCS4 and/or NCS5 to access other parallel devices. 10.4.8 SPI0 and MCI Interface SPI0 signals and MCI0 signals are multiplexed, as the DataFlash Card is hardware-compatible with the SDCard. Only one can be used at a time. 39 6249BS–ATARM–18-Dec-06 10.4.9 Interrupts Using IRQ0 prevents using the CAN controller. Using FIQ prevents using DMA Request 2. 10.4.10 Image Sensor Interface Using ISI in 8-bit data mode prevents using timers TIOA1, TIOB1. Using ISI in extended mode (up to 12 bits) prevents using keyboard row lines. 10.4.11 Timers Using TC0 prevents using columns 1 and 2 of the Keyboard Interface. Using TIOA2 and TIOB2, in this order, prevents using SPI1’s Chip Selects [2-3]. 10.5 10.5.1 Embedded Peripherals Overview Serial Peripheral Interface • Supports communication with serial external
