Supply Controller). The NRST pin integrates a permanent pull-up resistor of about 100 kOhm to VDDIO. 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

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.

4.3.6 UART

The Universal Asynchronous Receiver Transmitter features a two-pin UART that can be used for com-munication 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.

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.

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.

2. The TDO pin is in input mode with the pull-up resistor disabled when the Cortex M3 is not in debug mode. To avoid current consumption on VDDIO and/or VDDCORE due to floating input, the internal pull-up resistor corresponding to this PIO line must be enabled.

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 sen-sitive 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.

Figure 4-12. User Buttons

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.

Figure 4-13. LEDs

4.3.15 ZigBee

SAM3N-EK has a 10-pin male connector for the RZ600 ZigBEE module.

Note: 0 Ohm resistors have been implemented in series with the PIO lines that are used else-where in the design, thereby enabling their individual disconnection, should a conflict occur in your application.

Figure 4-14. ZigBee

4.3.16 PIO Expansion

The SAM3N product features three PIO controllers, PIOA, PIOB and PIOC, which are multiplexed with the I/O lines of the embedded peripherals. Each PIO Controller controls up to 32 lines (15 for PIOB).

Expansion ports J5, J6 provide PIO lines access for customer defined usage.

5.5 Hardware Description

5.5.1 QT600 Interface Board

Figure 5-6. QT600 Interface Board

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.

The QT600 can also be used as a programmer for programming the on-chip flash memory of the micro-controllers on the SAM3N-EK board.

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 pro-grammed, 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 anSPI (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 instruc-tions on how to add the QT600 protocol files to your firmware project.
