The chip select signals SDCS and NCS0 are used for SDRAM and NAND-Flash chips selection, respec-tively. Furthermore, a dedicated jumper can disconnect these from the memories, to let SDCS and NCS0 be used for other custom purpose.

4.3.3 Clock Circuitry

The clock generator of a SAM3X8H microcontroller is made up of:

A Low Power 32,768 Hz Slow Clock Oscillator with bypass mode

A 3 to 20 MHz Crystal Oscillator, which can be bypassed (12 MHz needed in case of USB)

High precision 8/12 MHz factory trimmed internal RC oscillator with 4 MHz Default Frequency for fast device startup

A 480 MHz UTMI PLL providing a clock for the USB High Speed Controller

A 96 to 192 MHz programmable PLL (input from 8 to 16 MHz), capable of providing the clock MCK to the processor and to the peripherals.

The SAM3X-EK board is equipped with one 12 MHz crystal, one 32,768 Hz crystal.

Figure 4-4. External Clock Source

4.3.4 Reset and Wake-Up Circuitry

The on-board NRST button BP1 and NRSTB button BP2 provide the SAM3X8H with external reset con-trol. The on-board WAKE-UP button BP3 can be used to wake up the chip from low power modes.

Figure 4-5. System Buttons

The NRST pin is bidirectional. It is handled by the on-chip reset controller and can be driven low to pro-vide a reset signal to the external components, or asserted low externally to reset the microcontroller. It will reset the Core and the peripherals except the Backup region (RTC, RTT and Supply Controller). There is no constraint on the length of the reset pulse, in any case the reset controller guarantee a mini-mum pulse length. The NRST pin integrates a permanent pull-up resistor to VDDIO of about 100 k?.

On the SAM3X-EK board, the NRST signal is connected to the LCD module, JTAG port and Ethernet Physical Transceiver.

The NRSTB pin is input only and enables asynchronous reset of the SAM3X/A series when asserted low. The NRSTB pin integrates a permanent pull-up resistor of about 15 kOhms. This allows connection

of a simple push button on the NRSTB pin as a system-user reset. In all modes, this pin will reset the chip including the Backup region (RTC, RTT and Supply Controller). It reacts as the Power-on reset. It can be used as an external system reset source. In harsh environments, it is recommended to add an external capacitor (10 nF) between NRSTB and VDDBU. (For filtering values, refer to “I/O characteris-tics” in the “Electrical Characteristics” section of the product datasheet) The NRSTB input has an embedded anti-glitch filtering system.

The FWUP pin is enabled as a wake up source by writing the FWUPEN bit to 1 in the Supply Controller Wake Up Mode Register (SUPC_WUMR). Then, the FWUPDBC field in the same register selects the debouncing period, which can be selected between 3, 32, 512, 4,096 or 32,768 slow clock cycles. This corresponds respectively to about 100 µs, about 1 ms, about 16 ms, about 128 ms and about 1 second (for a typical slow clock frequency of 32 kHz). Programming FWUPDBC to 0x0 selects an immediate wake up, i.e., the FWUP must be low during a minimum of one slow clock period to wake up the core power supply. If the FWUP pin is asserted for a time longer than the debouncing period, a wake up of the core power supply is started and the FWUP bit in the Supply Controller Status Register (SUPC_SR) is set and remains high until the register is read.

4.3.5 Power Supply and Management

The SAM3X-EK board is supplied with an external 5V DC block through input J1. A protection circuitry is obtained by a PolyZen diode MN1 and an LC combinatory filter MN2.

The adjustable LDO regulator MN3 is employed for the main supply of the 3.3V rail. It powers all the 3.3V board components. The shut down control of this LDO is made by MOSFETs Q1, Q2 piloted by the SAM3X8H SHDN pin. When SAM3X8H is in backup mode, SHDN pin outputs a low level signal, which shuts down the LDO. When the device is running (not in backup mode), SHDN pin outputs a high level signal, which enables the LDO.

By closing the “FORCE POWER ON” jumper JP3, the P-channel MOSFET Q1 will be forced on, no mat-ter the level present on the SHDN pin, and the LDO 3.3V output will thereby be forced active.

Figure 4-6. Power Block

The SAM3X-EK board uses the 3.3V LDO output as its main supply source. VDDUTMI, VDDANA, VDDIO, VDDIN are powered directly from that source.

The internal 1.8V regulator output feeds VDDCORE and VDDPLL.

4.3.6 UART

The Universal Asynchronous Receiver Transmitter features a two-pin UART that can be used for com-munication and trace purposes and offers an ideal medium for on-site programming solutions. Moreover, the association with two peripheral DMA controller (PDC) channels permits packet handling for these tasks with processor time reduced to a minimum.

This two-pin UART (TXD and RXD only) is buffered through an RS232 Transceiver MN14 and brought to the DB9 male connector J11.

Figure 4-8. UART

4.3.7 USART

The Universal Synchronous Asynchronous Receiver Transceiver (USART) provides one full duplex uni-versal synchronous asynchronous serial link. Data frame format is widely programmable (data length, parity, number of stop bits) to support a maximum of standards. The receiver implements parity error, framing error and overrun error detection. The receiver time-out enables handling variable-length frames and the transmitter timeguard facilitates communications with slow remote devices. Multidrop communi-cations are also supported through address bit handling in reception and transmission.

The USART features three test modes: remote loopback, local loopback and automatic echo.

The USART supports specific operating modes providing interfaces on RS485, LIN and SPI buses, with ISO7816 T = 0 or T = 1 smart card slots and infrared transceivers. The hardware handshaking feature enables an out-of-band flow control by automatic management of the pins RTS and CTS.

The USART supports the connection to the Peripheral DMA Controller, which enables data transfers to the transmitter and from the receiver. The PDC provides chained buffer management without any inter-vention of the processor.

The LCD module gets its reset from NRST. As explained previously, this NRST is shared with the JTAG port and the push button BP1. The LCD chip select signal is connected to NCS2 (a dedicated jumper can disable it, making NCS2 available for other custom usage).

The SAM3X8H communicates with the LCD through PIOC where a 16-bit parallel “8080-like” protocol data bus has to be implemented by software.

Figure 4-12. LCD Block

4.3.9.2 Backlight Control

LCD backlight is made of 4 white chip LEDs in parallel, driven by an AAT3194 charge pump, MN10. The AAT3194 is controlled by the SAM3X8H through a single line Simple Serial Control (S2Cwire) interface, which permits to enable, disable, and set the LED drive current (LED brightness control) from a 32-level logarithmic scale. Four 0-Ohm resistors R44/R45/R46/R47 are implemented for optional current limita-tion (replace 0 Ohm with the required resistor value).

Figure 4-13. Backlight Control

4.3.9.3 Touch Screen Interface

The LCD module integrates a 4-wire touch screen panel controlled by MN9, ADS7843, which is a slave device on the SAM3X8H SPI bus.

The ADS7843 touch ADC auxiliary inputs IN3/IN4 are connected to test points for optional function extension.

4.3.10 JTAG/ICE

A standard 20-pin JTAG connector is implemented on the SAM3X-EK for any ARM JTAG emulator con-nection, such as SAM-ICE from Segger.

Note that the NRST net is connected to the system button BP1, and is also used to reset the LCD mod-ule. 0-Ohm resistor R24 may be removed in order to isolate the JTAG port from the system reset signal.

Figure 4-15. JTAG Connector

4.3.11 Audio Codec

The SAM3X-EK includes a WOLFSON codec WM8731 for digital sound input and output. This interface includes audio jacks for:

microphone input

headphone output

The SAM3X8H programmable clock output is used to generate the WM8731 master clock (MCLK). The SAM3X8H ODT (On-Die Termination) feature guarantees a signal integrity on this clock line without the need for external discrete components.

WM8731 pin 21 MODE is pulled down by default; this configures the device as a TWI device for internal register access.

Pin15 CSB is pulled up, which sets its TWI address as 33 [0x0011011].

The WM8731 digital interface works in slave mode on the SAM3X8H Synchronous Serial Controller (SSC) interface, which means that Codec digital audio bit clock and ADC/DAC left/right control clock are to be generated by the SAM3X8H.

The WM8731 ADC and DAC have separated left/right control clocks to run at different rates.

The bit clock is shared; it can be the SSC transmitter clock (TK) or the receiver clock (RK). The default setting on SAM3X-EK is TK and RK shorted together through R71/R72. Please note that trying different ADC/DAC rates would mean different RK/TK rates; this default setting can be modified.

The 0-Ohm resistors R71/R72/R73/R74 have been implemented to offer a disconnection possibility (freeing these dedicated PIO lines for other custom usage).

4.3.12 USB

The SAM3X8H USB port is compliant with the Universal Serial Bus (USB) rev 2.0 specification at all speeds. J3 is a micro AB-type receptacle for USB Host/Device.

Both R25 and R26 39-Ohm resistors build up a 90-Ohm differential impedance together with the 5-Ohm output impedance of the Hi-speed channel drivers.

MN4 build up a power controler to guarantee the mode of USB can be switched between Device and Host mode.

4.3.20 Ethernet MAC 10/100 (EMAC)The EMAC module implements a 10/100 Ethernet MAC compatible with the IEEE 802.3 standard using an address checker, statistics and control registers, receive and transmit blocks, and a DMA interface. The SAM3X-EK is equipped with a Davicom DM9161AEP 10/100 Mbps Fast Ethernet Physical Layer TX/FX Single Chip Transceiver. It contains the entire physical layer functions of 100BASE-TX as defined by IEEE 802.3u, including the Physical Coding Sublayer (PCS), Physical Medium attachment (PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD), 10BASE-TX Encoder/Decoder (ENC/DEC), and Twisted Pair Media Access Unit (TPMAU).The Ethernet interface provides RMII (Reduced MII), for 100Base-TX or 10Base-TX. The RMII interfaces are capable of both 10Mb/s and 100Mb/s data rates as described in the IEEE 802.3u standard. The Ethernet interface integrates an RJ45 connector with an embedded transformer, and three statusLEDs. For guarantee DM9161AEP is reset properly, a reset IC MN19 is integrated too.

Figure 4-27. Ethernet Block

4.3.21 CAN

The CAN controller provides all the features required to implement the serial communication protocol CAN defined by Robert Bosch GmbH, the CAN specification as referred to by ISO/11898A (2.0 Part A and 2.0 Part B) for high speeds and ISO/11519-2 for low speeds. The CAN Controller is able to handle all types of frames (Data, Remote, Error and Overload) and achieves a bit rate of 1 Mbit/sec.

The SAM3X8H has two CAN Controllers with eight Mailboxes.

4.4.3 Test Points

Some test points have been placed on the SAM3X-EK board for the verification of important signals.

4.4.4 Assigned PIO Lines, Disconnection Possibility

As pointed out previously in the interface description, 0 Ohm resistors have been inserted on the path of the receiver PIO lines of the SAM3X-EK. These are the PIO lines connected to an external driver on the board. The 0 Ohm resistors allow disconnecting each of these for custom usage (through PIO expansion connectors for example). This feature gives the user an added level of versatility for prototyping a system of his own. See the table below.
