3. Xplained Pro

SAM V71 Xplained Ultra implements several Xplained Pro standards like extension headers and connectors, this chapter documents these standards.
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The platform consists of a series of Microcontroller (MCU) boards and extension boards that are integrated with Atmel Studio, support data streaming and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards that are connected through a set of standardized headers and connectors. Each extension board has an identification (ID) chip to uniquely identify which boards are connected to a Xplained Pro MCU board. This information is used to present relevant user guides, application notes, datasheets, and example code through Atmel Studio.

3.1. Embedded Debugger

The SAM V71 Xplained Ultra contains the Atmel Embedded Debugger (EDBG) for on-board debugging. The EDBG is a composite USB device of three interfaces; a debugger, Virtual COM Port, and a Data Gateway Interface (DGI).
Together with Atmel Studio, the EDBG debugger interface can program and debug the ATSAMV71Q21. On SAM V71 Xplained Ultra, the SWD interface is connected between the EDBG and the ATSAMV71Q21.
The Virtual COM Port is connected to a UART on the ATSAMV71Q21 and provides an easy way to communicate with the target application through terminal software. It offers variable baud rate, parity, and stop bit settings. Note that the settings on the ATSAMV71Q21 must match the settings given in the terminal software.
Note:  If not set automatically, data terminal ready (DTR) must be set in the terminal software.
The DGI consists of several physical interfaces for communication with the host computer. Communication over the interfaces is bidirectional. It can be used to send events and values from the ATSAMV71Q21 or as a generic printf-style data channel. Traffic over the interfaces can be timestamped on the EDBG for more accurate tracing of events. Note that timestamping imposes an overhead that reduces maximal throughput. Atmel Data Visualizer is used to send and receive data through DGI.
The EDBG controls two LEDs on SAM V71 Xplained Ultra; a power LED and a status LED. Table 3-1 
EDBG LED Control on page 7 shows how the LEDs are controlled in different operation modes.
Table 3-1 EDBG LED Control
Operation Mode Power LED Status LED
Normal operation Power LED is lit when power is
applied to the board.
Bootloader mode (idle) The power LED and the status LED blinks simultaneously.

3.2. Hardware Identification System

All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication™ chip mounted. This chip contains information that identifies the extension with its name and some extra data. When an Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information, code examples, and links to relevant documents. Table 3-2 Xplained Pro ID Chip Content on page 8 shows the data fields stored in the ID chip with example content.

4. Hardware Users Guide

4.1. Power Distribution

SAM V71 Xplained Ultra has four power sources as described in Power Sources on page 8. Figure 4-1 
Power Supply Block Diagram on page 13 shows a block diagram of the power supply circuitry, the
related I/O pins are described in Table 4-1 Power Distribution Signals on page 14.
The kit can be powered from the EDBG USB, Target USB, external 5.0V, and/or a 5-14V DC jack input. The kit will automatically select a source to draw power from.
An on board supercap (100mF) is charged to 3.6V from the kits 5V net. When all external power is removed from the board or the 3.3V regulator is disabled by the application running on the ATSAMV71Q21 the power switch will supply the ATSAMV71Q21 from the supercap. It is intended that the supercap can supply the ATSAMV71Q21 in its low power backup mode.
Info:  When the on-board regulator is turned off by the target application in the ATSAMV71Q21, all ICs on the kit are unpowered except the ATSAMV71Q21. Care must be taken to not supply and stray power these ICs through the ATSAMV71Q21s I/O pins.

4.2.4. MediaLB Connector

Media Local Bus (MediaLB) is an on-PCB or inter-chip communications bus, specifically designed to standardize a common hardware interface and software API library. This standardization allows an application or multiple applications to access the MOST® (Media Oriented Systems Transport) Network data, or to communicate with other applications, with minimum effort.
On SAM V71 Xplained Ultra the MLB module of the ATSAMV71Q21 is connected to a MediaLB connector implemented with a 40 pin SAMTEC QSH-020-01-L-D-DP-A. This connector is intended to interface with a board that includes the MOST INIC and the MOST-50 physical layer connector (such as a Physical+ Interface Board OS81092 ePhy) or with other MOST tools. Table 4-13 MediaLB Connector on page 23 shows all connections between the ATSAMV71Q21 and the connector.

Caution:  Removing the jumper from the pin-header while the kit is powered will power all power pins on the ATSAMV71Q21 except VDDCORE. This may cause permanent damage to the device.

4.2.10. Chip Erase Header

There is a 1x2 pin-header that is connected to the SAM V71 chip erase pin, PB12, and 3V3 marked ERASE. This header can be used to chip erase the SAM V71 by placing jumper on the header and toggle power to the board. After the power is toggled the jumper should be removed. Using the chip erase jumper may be the only way to erase a chip with the security bit set, and applications that immediately sets invalid clock options or goes into deep sleep without any wake-up sources enabled.

4.2.11. Trace Connector

ATSAMV71Q21 supports 4-bit parallel trace. SAM V71 Xplained Ultra implements a CoreSight 20 20-pin, 50-mil keyed connector (pin seven is removed).
To use the trace functionality an external debugger with trace support and CoreSight 20 pin out has to be used. Table 4-18 CoreSight 20 Trace Connector on page 27 shows the connections on the kit.
Info:  Several of the trace signals are shared with Ethernet signals, this means that there is no trace support if Ethernet is used in an application.

4.3.7. Ethernet

ATSAMV71Q21 has a built in 10/100Mbps Ethernet IEEE® 802.3 compatible MAC with RMII and MII interface. The MAC also supports energy efficient Ethernet (IEEE 802.3az) and Ethernet Audio Video Bridging (AVB) including IEEE 802.1AS and IEEE802.1Qav. SAM V71 Xplained Ultra connects the MAC to a Micrel KSZ8061RNBVA RMII physical-layer transceiver (PHY), with IEEE 802.3az support, which is connected to one RJ45 Ethernet connector.
A unique EUI-48 address is available on every SAM V71 Xplained Ultra through the on-board
AT24MAC402, the EUI-48 address can be used as a MAC address for the KSZ8061RNBVA. The address
is also programmed into the on board EDBG. For more information, see Kit Specific Data on page 42.
Table 4-26 KSZ8061RNBVA Connections on page 32 lists all pins connected from the ATSAMV71Q21
to the Ethernet PHY.
Info:  Several of the Ethernet signals are shared with the trace connector, this means that there is no Ethernet support if trace is used in an application.

4.3.10. Audio and External PLL

SAM V71 Xplained Ultra includes a WOLFSON WM8904 Audio CODEC for input and output of digital sound, the kit has two 3.5mm stereo jacks for microphone input and headphone output. There is also an (optional) external PLL, Cirrus Logic CS2100CP, that can be used to generate a reference clock to the WM8904. In an Ethernet AVB application, the CS2100CP PLL can be used to accurately reconstruct a media clock that is generated at a remote network node.
The WM8904 is configured through I2C while audio data is transferred via the SSC module in the SAM V71. The CS2100CP PLL is also configured through I2C, and the input clock reference is from PD21 which is internally connected to the timer unit of the Ethernet MAC in the ATSAMV71Q21.

6. Hardware Revision History and Known Issues

6.1. Identifying Product ID and Revision

The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel Studio or by looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information window will pop up. The first six digits of the serial number, which is listed under kit details, contain the product identifier and revision. Information about connected Xplained Pro extension boards will also appear in the Atmel Kit's window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the identifier and revision in plain text as A09-nnnn\rr, where nnnn is the identifier and rr is the revision. Boards with limited space have a sticker with only a QR-code, which contains a serial number string.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The product identifier for SAM V71 Xplained Ultra is A09-2241.

6.2. EBI Signal Integrity

The ATSAMV71Q21 has on-die series termination on every I/O pin as shown in Figure 6-1 On-Die
Termination on page 44.
Some of the pins that belong to the External Bus Interface (EBI) are connected to the on-board SDRAM and the Xplained Pro LCD connector (EXT4). When a cable is plugged into the LCD connector long stubs are created on the signal lines, the stubs create ringing that reduces the maximum clock speed, which can be used when communicating with the SDRAM.
For more detailed information about termination strategies, see application note AT91-AN02: Signal
Integrity and AT91 Products.
All designs should be simulated using an IBIS file for the ATSAMV71Q21 and the target peripherals to check that the signals are within the limits of the devices.

6.3. 12MHz Crystal Selection

The selected 12MHz crystal FQ5032B-12-C-C-C-200-1 has a load of 20pF, this is outside the recommended range of 12.5pF to 17.5pF in the ATSAMV71Q21 datasheet. Using a crystal with loads outside the recommended range can cause instability when operating the device close to maximum/ minimum parameters for supply voltage and temperature.
Fix/Workaround: None, any new design should select a crystal within the limits specified in the
datasheet.

6.4. Revision 9

Revision 9 of SAM V71 Xplained Ultra has engineering samples mounted with part number ATSAMV71Q21A-AAB-ES4.
Revision 9 of SAM V71 Xplained Ultra is otherwise identical to revision 8.

6.5. Revision 8

Revision 8 of SAM V71 Xplained Ultra has engineering samples mounted with part number ATSAMV71Q21A-AAB-ES2 or ATSAMV71Q21A-AAB-ES3.
Revision 8 of SAM V71 Xplained Ultra uses PCB (A08-2216) revision 3.
Revision 8 of SAM V71 Xplained Ultra fixes the issues described in Revision 6 on page 45.

6.5.1. PCB Revision Marking

One thousand SAM V71 Xplained Ultra revision 8 kits have revision 3 PCBs (A08-2216) that are marked with "Revision 2" under the location of the serial number sticker.
These PCBs can be identified by the addition of the "USB VBUS" and "SUPER CAP" connectors shown in Figure 4-2  SAM V71 Xplained Ultra Connector Overview on page 15 that were not present in revision 2 of the PCB.
Atmel SAM V71 Xplained Ultra [USER GUIDE]

6.6. Revision 6

Revision 6 of SAM V71 Xplained Ultra has engineering samples mounted with part number ATSAMV71Q21A-AAB-ES2.
Revision 6 of SAM V71 Xplained Ultra uses PCB (A08-2216) revision 2.

6.6.1. Device Marking

Some revision 6 kits may have SAM V71 devices marked as ATSAMX7EA-AU-ES2, these devices are equivalent to ATSAMV71Q21A-AAB-ES2.

6.6.2. Camera Connector and Audio

PD11 is shared between the camera connector ISI_D6, Audio CODEC IRQ, an Arduino connector, and Xplained Pro extension header 2 GPIO (EXT2). PD11 is pulled low strongly by the Audio CODEC and the pin is not usable by any other source unless it is disconnected. Removing R200 will disconnect PD11 from the Audio CODEC interrupt pin freeing it up to be used for camera and extension applications.
PD28 is shared between the camera connector ISI_D9, Arduino connectors, LCD extension connector IRQ1 (EXT4), and Xplained Pro extension header 1 IRQ (EXT1). If a camera with 10-bit mode is used together with a display connected to EXT4 the display IRQ line will conflict with the camera.
On revision 6 of SAM V71 Xplained Ultra pin 41 (DISPLAY ENABLE) on the LCD connector is not connected to anything (floating).

6.6.3. Super Capacitor

The charging circuit for the on-board super capacitor described in Power Distribution on page 13 does not work as intended. It is therefore not possible to run the ATSAMV71Q21 from the on-board super capacitor. It is, however, fully possible to run the ATSAMV71Q21 in low power modes with external power connected and measure the devices power consumption trough the Current Measurement Header on page 26.
Revision 6 of SAM V71 Xplained Ultra does not have the super capacitor disconnect pin-header described in Super Capacitor on page 26.

6.6.4. Connectors

Revision 6 of SAM V71 Xplained Ultra has fewer connectors than newer revision. Figure 6-2  SAM V71
Xplained Ultra Connector Overview on page 46 is applicable for revision 6 instead of the figure
described in Figure 4-2  SAM V71 Xplained Ultra Connector Overview on page 15.

6.6.5. Target USB

Revision 6 of SAM V71 Xplained Ultra does not have the ability to detect power on the target USB connector. The pin-header marked "USB VBUS" in Figure 4-2  SAM V71 Xplained Ultra Connector
Overview on page 15 and described in Table 4-16 USB VBUS Selection on page 26 is not implemented
in the PCB.

6.6.6. Ethernet RJ-45 Connector

On revision 6 of SAM V71 Xplained Ultra the TX and RX differential pairs has a swapped position on the RJ-45 connector compared to what is normal.
