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). -
Page 11: Power Supply And Management
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. -
Page 12: Display Interface
FGND 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. -
Page 13: Jtag/Ice
4.3.9 JTAG/ICE A standard 20-pin JTAG/ICE connector is implemented on the SAM3N-EK for the connection of a com- patible ARM JTAG emulator interface, such as the SAM-ICE from Segger. Notes: 1. The NRST signal is connected to BP1 system button. The 0 ohm resistor R30 may be removed in order to isolate the JTAG port from this system reset signal. -
Page 14: Touch Elements
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. -

Page 20: Assigned Pio Lines, Disconnection Possibility
As pointed out in previous interface descriptions, 0-Ohm resistors have been inserted on the PIO lines receiver path of the SAM3N-EK. Some PIO lines are connected to an external driver on the board. The 0-Ohm resistors allow disconnecting each of these for custom usage (through PIO expansion connec- tors, for example). -

Page 25: Hardware Description
The QT600 Interface Board is the communication interface between the touch system (presently SAM3N-EK) and the AVR QTouch Studio. It receives touch signal data from the MCU running the QTouch Library, and forwards this data to the AVR QTouch Studio for visual presentation. - Page 26 QT600 Figure 5-7.
