WARNING
ESD-Sensitive Electronic Equipment!
The evaluation kit is shipped in a protective anti-static package. The board system
must not be subject to high electrostatic potentials.
We recommend using a grounding strap or similar ESD protective device when
handling the board in hostile ESD environments (offices with synthetic carpet, for
example). Avoid touching the component pins or any other metallic element on
the board.

sensitive
device
WARNING
Hardware Power Supply Limitation
Powering the board with voltages higher than 5 VCC (e.g., the 12 VCC power
adapters from other kits such as Arduino kits) may damage the board.
WARNING
Hardware Power Budget
Using the USB as the main power source (max. 500 mA) is acceptable only with the
use of the on-board peripherals and low-power LCD extension.
When external peripheral or add-on boards need to be powered, we recommend
the use of an external power adapter connected to the USB Micro-AB connectors
(can provide up to 1.2A on the 3.3V node).

2. Power Source
Several options are available to power up the SAMA5D2-XULT board:
USB-powered through the USB Micro-AB connector (J23 - default configuration)
Powered through a rechargeable battery Li-polymer 3.7V connected to J3 or J4
Powered through the USB Micro-AB connector on the Atmel Embedded Debugger (EDBG) interface (J14)
2.1 Power up the Board
Unpack the board, taking care to avoid electrostatic discharge. Connect the USB Micro-AB cable to the connector
(J23). Then connect the other end of the cable to a free USB port of your PC.
WARNING
Unlike Arduino Uno boards, the SAMA5D2-XULT board runs at 3.3V. The maximum
voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages (e.g., 5V) to
an I/O pin could damage the board.

The three DC-DC converters utilize a high efficiency, fixed-frequency (2 MHz), current-mode PWM control
architecture that requires a minimum number of external components. Two DC-DC converters are capable of
supplying up to 1100 mA of output current, while the third supports up to 1200 mA. All four low-dropout linear
regulators are high performance, low-noise regulators that supply up to 320 mA of output current.
Figure 5-3. Board Power Management
Note: 1. Occasional board startup problems occurred when powered from a USB source having a weak VBUS level below 4.8V. To
avoid the voltage drop and consequential startup problems, production boards were assembled with a 0 Ω resistor in place
of the Schottky diode D9 shown here.

5.3.2.4 Power Boost 5V
To generate a true 5V voltage from the PMIC output (4.8V typical), a FAN48610 low-power boost regulator is
integrated into the design. This feeds the 5V USB host and the 5V LCD.
Figure 5-4. Power Boost 5V
5.3.2.5 Input Power Options
There are several power options for the SAMA5D2-XULT board.
The USB-powered operation is the default configuration. It comes from the USB device port connected to a PC or
a 5V DC supply. The USB supply is sufficient to power the board in most applications. It is important to note that
when the USB supply is used, the USB-B Host port has limited power. If USB Host port is required for the
application, it is recommended that an external DC supply be used.
Figure 5-5 provides the schematics of power options.
Figure 5-5. Input Powering Scheme
Note: USB-powered operation eliminates additional wires and batteries. It is the preferred mode of operation for
any project that requires only a 5V source at up to 500 mA.
5.3.2.6 Battery Supply Source
The ACT8945A features an advanced battery charger that incorporates the ActivePath architecture for system
power selection. This combination of circuits provides a complete, advanced battery-management system that
automatically selects the best available input supply, manages charge current to ensure system power availability,
and provides a complete, high accuracy (±0.5%), thermally regulated, full-featured single-cell linear Li+ charger.
The ActivePath circuitry monitors the state of the input supply, the battery, and the system, and automatically
reconfigures itself to optimize the power system. If a valid input supply is present, ActivePath powers the system
from the input while charging the battery in parallel. This allows the battery to charge as quickly as possible, while
supplying the system. If a valid input supply is not present, ActivePath powers the system from the battery. Finally,
if the input is present and the system current requirement exceeds the capability of the input supply, ActivePath
allows system power to be drawn from both the battery and the input supply.

Figure 5-6. Battery Powering Scheme
Charger Input Interrupts
In order to ease input supply detection and eliminate the size and cost of external detection circuitry, the charger
has the ability to generate interrupts based upon the status of the input supply. This function is capable of
generating an interrupt when the input is connected, disconnected, or both, when the charger state machine
transitions.
Charge Status Indicator
The charger provides a charge-status indicator output, nSTAT. nSTAT is an open-drain output which sinks current
when the charger is in an active-charging state, and is high-Z otherwise. nSTAT features an internal 8 mA current
limit, and is capable of directly driving a LED (D1).
Precision Voltage Detector
The LBI input connects to one input of a precision voltage comparator, which can be used to monitor a system
voltage such as the battery voltage. An external resistive-divider network can be used to set voltage monitoring
thresholds. The output of the comparator is present at the nLBO open-drain output and connected to the led red
D1.

5.3.2.7 Backup Power Supply
The SAMA5D2-XULT board requires a power source in order to permanently power the backup part of the
SAMA5D2 device (refer to SAMA5D2 Series datasheet). A super capacitor sustains such permanent power to
VDDBU when all system power sources are off.

5.3.5 Memory
5.3.5.1 Memory Organization
The SAMA5D2 features a DDR/SDR memory interface and an External Bus Interface (EBI) to permit interfacing to
a wide range of external memories and to almost any kind of parallel peripheral.
This section describes the memory devices that equip the SAMA5D2-XULT board.
5.3.5.2 DDR3/SDRAM
Two DDR3L/SDRAM (MT41H128M16JT-125-K - 2 Gbit = 16 Mbit x 16 x 8 banks) are used as main system
memory and totalling 4 Gbit of SDRAM on the board. The memory bus is 32 bits wide and operates with a
frequency of up to 166 MHz.

5.3.5.5 CS Disable
The SAMA5D2 device boots according to the following sequence:
1. SD CARD connected on SDHC1
2. DataFlash connected on NPCS0 SPI0
3. Optional QSPI flash connected on QSPI0 QSPI_CS0
4. eMMC connected to SDHC0
In this sequence, the first device found with bootable contents is selected as the boot source. The others are
disregarded.
On-board jumper (JP9) controls the selection (CS#) of the on-board bootable memory components (eMMC and
Serial DataFlash) using a non-inverting 3-state buffer.
Figure 5-14. CS Disable
The rule of operation is:
JP9 = OFF (default) → enable normal boot from eMMC or serial Flash if mounted
JP9 = ON → booting from optional serial DataFlash or eMMC is disabled
Refer to the SAMA5D2 Series datasheet for more information on standard boot strategies and sequencing.

5.3.6 Additional Memories
5.3.6.1 Serial Data Flash
The SAMA5D2 provides two high-speed Serial Peripheral Interface (SPI) controllers. One port is used to interface
with the on-board serial DataFlash.
The four main signals used in the SPI are Clock, Data In, Data Out, and Chip Select. The SPI is a serial interface
similar to the I
2
C bus interface but with three main differences:
It operates at a higher speed.
Transmit and receive data lines are separate.
Device access is chip select-based instead of address-based.
Figure 5-15. Serial DataFlash
5.3.6.2 QSPI Serial Flash
The SAMA5D2 provides two Quad Serial Peripheral Interfaces (QSPI). One port is used to interface with the optional
on-board QSPI serial DataFlash.
The Quad SPI Interface (QSPI) is a synchronous serial data link that provides communication with external
devices in Master mode.
The QSPI can be used in SPI mode to interface to serial peripherals (such as ADCs, DACs, LCD controllers, CAN
controllers and sensors), or in Serial Memory mode to interface to serial Flash memories.
The QSPI allows the system to execute code directly from a serial Flash memory (XIP) without code shadowing to
RAM. The serial Flash memory mapping is seen in the system as other memories (ROM, SRAM, DRAM,
embedded Flash memory, etc.).
With the support of the Quad SPI protocol, the QSPI allows the system to use high-performance serial Flash
memories which are small and inexpensive, in place of larger and more expensive parallel Flash memories
