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 strongly 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.

WARNING
Hardware Power Supply Limitation
Using a power adapter greater than 5Vcc (e.g. the 12Vcc 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 a J2 DC Jack (can provide up to
1.2A on the 3.3V node).

2. Power Up
Several power source options are available to power up the SAMA5D3 Xplained board.
The board can be:
USB-powered through the USB Micro-AB connector (J6 connector - default configuration)
Powered through an external AC-to-DC adapter connected via a 2.1 mm center-positive plug into the
optional power jack of the board. The recommended output voltage range of the power adapter is 5V at 2A.
Powered through the Arduino shield.
2.1 Power up the Board
Unpack the board, taking care to avoid electrostatic discharge. Simply connect the USB Micro-AB cable to the
connector (J6).Then, connect the other end of the cable to a free USB port of your PC.
2.2 Sample Code and Technical Support
After booting up the board, you can run sample code or your own application on the board. You can download
sample code and get technical support from the Atmel website.
Linux software and demos can be found on the website Linux4SAM.
WARNING
Unlike Arduino Uno boards, the SAMA5D3 Xplained 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.

4.2.1 Processor
The SAMA5D3 Xplained board is built around the SAMA5D36, a Cortex-A5 application processor which combines
high-performance computing device with low-power consumption and a wide range of communication peripherals.
It features a combination of user interface functionalities and high data rate IOs, including LCD controller,
touchscreen, camera interface, Gigabit and 10/100 Ethernet ports, high-speed USB and SDIO.
The ARM Cortex-A5 supports the latest generation of DDR2 and NAND Flash memory interfaces for program and
data storage. An internal 166-MHz multi-layer bus architecture associated with 24 DMA channels and two 64-
Kbyte SRAM blocks, sustains the high bandwidth required by the processor and the high-speed peripherals.
4.2.2 Clock Circuitry
The SAMA5D3 Xplained evaluation board features four clock sources:
Two clocks are alternatives for the SAMA5D3 series processor main clock
Two crystal oscillators are used for the GETH and Ethernet MII/RMII chip
4.2.3 Power Supplies
The on-board power supply generation is based on the Active-Semi®Power Management Unit (PMU) featuring a
3-channel (3.3V / 1.8V /1.2V or 1.0V) topology. For maximum efficiency, these supply channels are generated by
three integrated step-down converters.
In addition to these 3 DCDC channels, 4 LDO channels with low noise and high PSRR performance are available
for the application. These channels are disabled at startup by default and can be turned on and adjusted under
software control through an I²C link. They are also used to supply the 2.5V VDDFUSE and the 3.3V VDDANA
power inputs of the processor.
The power supply sequencing of the three primary channels is controlled by the PMU itself in full compliance with
the SAMAD3 requirements. The turn-on sequence is: 3.3V first, then 1.8V and finally 1.2V.
Table 4-2. Main Components Associated with the Clock Systems
Quantity Description Component Assignment
1 Crystal for internal clock, 12 MHz Y1
1 Crystal for RTC clock, 32.768 kHz Y2
1 Oscillator for ethernet clock RGMII, 25 MHz Y3
1 Oscillator for ethernet clock RMII, 25 MHz Y4
WARNING
There is a known error on the ACT8865 I²C implementation. The port must be shut
off after configuration or problems may occur with devices using the same I²C
channel, e.g., TM43xx LCD display.
Refer to the ACT8865 datasheet at http://www.active-semi.com/ for more details.
