4.3.3 Clock Circuitry
The clock generator of a SAM3N microcontroller is made up of:
A Low Power 32,768 Hz Slow Clock Oscillator with bypass mode
A Low Power RC Oscillator
A 3 to 20 MHz Crystal Oscillator, which can be bypassed
A factory programmed fast internal RC Oscillator. 3 output frequencies can be selected: 4 (default
value), 8 or 12 MHz.
A 60 to 130 MHz programmable PLL (input from 3.5 to 20 MHz), capable to provide the clock MCK to
the processor and to the peripherals.
The SAM3N-EK board is equipped with one 12 MHz crystal, and one 32.768 Hz crystal. An optional
12 MHz Piezoelectric Ceramic Resonator can be mounted in place of the 12 MHz crystal (for low cost
clocking option evaluation).
Figure 4-3. SAM3N MCU
Evaluation Kit Hardware
4.3.4 Reset Circuitry
The on-board NRST button BP1 provides the SAM3N4C with external reset control.
Two User buttons BP2 and BP3, can be used to wake up the chip from low power modes.
The NRST pin is bidirectional. It is handled by the on-chip reset controller. It can be driven low to provide
a reset signal out to the external components. Conversely, it can be asserted low from the outside to
reset the microcontroller, its core and peripherals, with exception of the backup region (RTC, RTT and

On the SAM3N-EK board, the NRST signal is connected to the JTAG port.
4.3.5 Power Supply and Management
The SAM3N-EK board is supplied with an external 5V DC block through the J1 socket. It is protected by
a PolyZen diode MN3. The PolyZen protects the board in the case of an incorrect power supply
connection.
The LDO regulator MN4 is used for the 3.3V main supply. It powers all the 3.3V components on the
board.
Figure 4-4. Power Block
4.3.6 UART
The SAM3N4/2/1 product series has different types of power supply pins:
VDDIN pin: Power for the internal voltage regulator, ADC, DAC, and analog comparator power
supplies. This voltage ranges from 1.8V to 3.6V.
VDDIO pin: Powers the Peripheral I/O lines, Backup part, 32 kHz crystal oscillator and oscillator pads.
This voltage ranges from 1.62V to 3.6V.
VDDOUT pin: Output of the internal voltage regulator.
VDDCORE pin: Powers the core, including the processor, the embedded memories and the
peripherals. This voltage ranges from 1.62V to 1.95V.
VDDPLL pin: Powers the PLL, the Fast RC and the 3 to 20 MHz oscillators. This voltage ranges from
1.62V to 1.95V.
The Universal Asynchronous Receiver Transmitter features a two-pin UART that can be used for communication and trace purposes. It offers an ideal channel for in-situ programming solutions. This UART
is associated with two PDC channels to reduce the processor time on packet handling.
The two-pin UART (TXD and RXD only) is buffered through an RS232 Transceiver MN8 and brought to
the DB9 male connector J4.

4.3.7 Display Interface
The SAM3N-EK carries a TFT Transmissive LCD module with touch panel, TM020GDZ18. Its integrated
driver IC is ILI9225B. The LCD display area is 2.0 inches diagonally measured, with a native resolution
of 176x220 pixels.
The LCD module gets reset from GPIO PA29. The LCD chip select signal is connected to NPCS2. The
SAM3N communicates with the LCD through the SPI bus.
Evaluation Kit Hardware
Figure 4-6. LCD
4.3.8 Backlight Control
The LCD backlight is made of four integrated white chip-LEDs arranged in parallel. These are driven by
an AAT3193 charge pump, MN5. The AAT3193 is controlled by the SAM3N through a single PIO line
interface (PC13); the 0 Ohm resistor R17 is mounted in series on this line, which permits to use it for
other custom purposes. In that case, the pull-up resistor R64 maintains the charge pump permanently
enabled by default.
On the anode drive line, a 0 Ohm resistor R21 is implemented in series for an optional current limitation.

Keys
The SAM3N-EK implements two individual capacitive touch keys (RIGHT, LEFT) using two pairs of
PIOs.
Slider
A group of channels forms a Slider. A Slider is composed of three channels for a QTouch acquisition
method using three pairs of PIOs. Such a sensor is used to detect a linear finger displacement on a sensitive area. A typical slider implementation is volume control.
4.3.13 User Buttons
There are two mechanical user buttons on the SAM3N-EK, which are connected to PIO lines and
defined to be "left" and "right" buttons by default.
In addition, a mechanical button controls the system reset, signal NRST.

4.3.14 LEDs
There are four LEDs on the SAM3N-EK board:
A blue LED (D1), a green LED (D2), and an amber LED (D3) which are user-defined and controlled by
the GPIO.
A red LED (D4), which is a power LED indicating that the 3.3V power rail is active. It is also controlled
by the GPIO and can be treated as a user LED as well. The only difference with the three others is that
it is controlled through a MOS transistor. By default, the PIO line is disabled; a pull-up resistor controls
the MOS to light the LED when the power is ON.

C:\ProgramFiles\Atmel\Atmel_QTouch_Libraries_4.3\Generic_QTouch_Libraries\AT91SAM\SAM3\
QTouch\example_projects\sam3n4_iar_qt_example
The Touch Data LED on the QT600 indicates the mode:
Touch Data LED green: Touch Debug Mode (default mode after power-up).
Touch Data LED off: Programmer Mode
Make sure that the Touch Data LED is off before attempting to connect to the QT600 from the QTouch
Studio programming dialog. Use AVR Studio 4.18 or later.
1. Connect the 10 wire flat-cable between the Touch Data header on the QT600 and the selected
SAM3N-EK board (see Figure 5-9 on page 5-7)
2. Make sure that VTG header is open on the QT600 (see “Target Voltage VTG” on page 5-8)
3. Start AVR QTouch Studio
4. Plug in the USB cable to the QT600. AVR QTouch Studio should now automatically connect to the
SAM3N-EK
5. Press the Start Debug button
You should now be able to view the touch data signals and the state of each sensor.

not lit.
5-8 SAM3N-EK Development Board User Guide
11080C–ATARM–30-Mar-11
5.5.6 STATUS LED
Green: Ready state
Orange: Busy programming
Orange/red flashing: Upgrade mode
Orange/green flashing: Upgrade mode, upgrade in progress
During programming, the LED is orange. When the Atmel target device has been successfully programmed, the LED turns green.
5.5.7 Touch ATx Firmware
The firmware for the Touch ATx is based on the QTouch Library. The QTouch Library handles the touch
acquisition. The touch measurement values are made available for the application firmware trough an
API, which is described in detail in the QTouch Library User Guide.
The touch measurement values available through the Touch Library API are sent to the QT600 with an
SPI (or PIO) interface, using a custom protocol. AVR QTouch Studio will read these data packets from
the QT600.
See the QT600 Protocol Document for details about the communication protocol.

5.6 Touch Debug
Before a touch debug session can be started, the target microcontroller on the SAM3N-EK board must
be programmed. The example projects can be retrieved from the QTouch Library (installation steps are
detailed in Section 5.4).
Example projects for both GCC and IAR compilers are available.
1. Connect a 10-wire cable between the Touch Data Connector on the SAM3N-EK board and the Touch
Data connector on the QT600 Interface board (see Figure 5-9 on page 5-7)
2. Start AVR QTouch Studio
3. Connect the USB cable to the QT600 interface board
4. Press the Start Debug Button in AVR QTouch Studio
AVR QTouch Studio automatically connects to the QT600 when the USB plug is inserted. The Touch
Data streaming starts when the "Start Debug" button is pressed.
5.7 Using QT600 and AVR QTouch Studio for Custom Applications
The QT600 Interface Board and QTouch Studio can be used to read touch data from any application
based on the QTouch Library. The only requirement is that there are two I/O pins available and that there
is enough free space in flash for the debug protocol and serial interface driver.
The QT600 interface uses an SPI protocol at a frequency of 200 kHz.
Complete firmware driver files are available in the QT600 example projects, which can be downloaded
from www.atmel.com/QT600. See the readme.txt file in the QT600 Example Projects folder for instructions on how to add the QT600 protocol files to your firmware project.

5.8 Troubleshooting and Support
5.8.1 Technical Support
For technical support, contact at91@atmel.com. When requesting technical support for the QT600, you
should provide the following information:
PC processor type and speed
PC operating system and version
Atmel target device used (complete part number)
Tar g e t v o l t ag e
Jumper settings
A detailed description of the problem
5.8.2 Force Firmware Upgrade
Before starting the procedure, make sure that the latest AVR Studio release (4.0 or later) has been
installed on your PC.
1. If connected to the PC with a USB cable, unplug the QT600.
2. Press and hold the button on QT600 when connecting the USB cable: the status LED flashes red
and orange, indicating the upgrade mode.
3. In AVR Studio, go to the Tools menu and select QT600 Upgrade.
4. The Atmel QT600 Upgrade program starts. If a connection has been established, the Status shows
"QT600 present".
5. Press the Start Upgrade button: the upgrade program upgrades QT600's firmware.
6. When complete, a message box indicates if the upgrade was successful or not. Disconnect and then
reconnect the USB cable.
7. If the upgrade was successful, the status LED turns green. Try to connect to the starter kit with
QTouch Studio.
The QT600 USB Bridge firmware must be updated using the batch file available in
“C:\...\QT600_USB_Bridge_Update” folder before using the Example projects.
