Module Connector The Mars XU3 SoC module fits into a 200-pin DDR2 SO-DIMM (1.8 V) socket. Up to four M2 screws may be used to mechanically fasten the module to the base board. Do not use excessive force to tighten the screws, as this could damage the module.
User I/O 2.9.1 Pinout Information on the Mars XU3 SoC module pinout can be found in the Enclustra Mars Master Pinout [11], and in the additional document Enclustra Module Pin Connection Guidelines [10]. Warning! Please note that the pin types on the schematics symbol of the module connector and in the Master Pinout document are for reference only.
The information regarding the length of the signal lines from the MPSoC device to the module connector is available in Mars XU3 SoC Module IO Net Length Excel Sheet [3]. This enables the user to match the total length of the differential pairs on the base board if required by the application.
VCC_IO_B[x], respectively VCC_CFG_[x] pins. All VCC_IO_B[x] or VCC_CFG_[x] pins of the same bank must be connected to the same voltage. For compatibility with other Enclustra Mars base boards and modules, it is recommended to use a single I/O voltage.
GPIOs; the suggested functions below are for reference only - always verify your MIO pinout with the Xilinx device handbook. Table 9 gives an overview over the MIO pin connections on the Mars XU3 SoC module. Only the pins marked with “user functionality” are available on the module connector.

Multi-Gigabit Transceiver (MGT) GTR Transceivers There are four GTR MGT pairs and two reference input clock differential pairs on the Mars XU3 SoC module connected to I/O bank 505, available on the module connector. The naming convention for the GTR MGT I/Os is: MGTPS_<FUNCTION>_<PACKAGE_PIN>_<POLARITY>.
Power Generation Overview The Mars XU3 SoC module uses a 3.3 - 5.0 V DC power input for generating the on-board supply voltages (0.72/0.85/0.9 V, 0.85/0.9 V, 1.2 V, 1.8 V, 2.5 V). Some of these internally-generated voltages are accessible on the module connector.
MIO pin 31) low. In this case the generated voltage for the PL core will be 0.72 V. The 0.9 V core supply for PS and PL is not supported, as the MPSoC devices equipped on the Mars XU3 SoC module are currently not available in speedgrade -3E, which would require a core voltage of 0.9 V.
For Enclustra Mars modules an Enclustra heat sink is available for purchase along with the product. It repre- sents an optimal solution to cool the Mars XU3 SoC module- it is low profile (less than 7 mm tall) and covers the whole module surface.
For details, please refer to the Enclustra website. Table 15 lists the heat sink and thermal pad part numbers that are compatible with the Mars XU3 SoC mod- ule. Details on these parts and additional information that may assist in selecting a suitable heat sink for the Mars XU3 SoC module can be found in the Enclustra Modules Heat Sink Application Note [18].
A 24 MHz clock and a 25 MHz clock are used for the USB PHY and Ethernet PHY respectively. The crystal pads for the MPSoC RTC are connected to a 32.768 kHz oscillator on the Mars XU3 SoC module. Table 17 describes the clock connections to the MPSoC device.
LEDs There are four active-low user LEDs on the Mars XU3 SoC module - two of them are connected to both PS and PL and two of them are connected to PS only. On revision 1 modules, all LEDs are connected to both PL and PS.
In custom configurations up to 4 GB of SDRAM memory may be equipped on the module. 2.15.2 Signal Description Please refer to the Mars XU3 SoC Module FPGA Pinout Excel Sheet [4] for detailed information on the DDR4 SDRAM connections. 2.15.3...
Table 22 describes the memory availability and configuration on the Mars XU3 SoC module. As there is one QSPI flash chip equipped on the Mars XU3 SoC module, type “single” must be selected when programming the flash from Vivado tools.
512 Mbit Cypress (Spansion) Table 22: QSPI Flash Type Warning! Other flash memory devices devices may be equipped in future revisions of the Mars XU3 SoC module. Please check the user manual regularly for updates. 2.16.2 Signal Description The QSPI flash is connected to the PS MIO pins 0-5. Some of these signals are available on the module connector, allowing the user to program the QSPI flash from an external source.
VCC_CFG_MIO must be set to 1.8 V. Please note that this boot mode has not been tested, but it may be supported in the future. 2.19 Gigabit Ethernet A 10/100/1000 Mbit Ethernet PHY is available on the Mars XU3 SoC module, connected to the PS via RGMII interface. 2.19.1 Ethernet PHY Type Table 24 describes the equipped Ethernet PHY device type on the Mars XU3 SoC module.
2.19.3 External Connectivity The Ethernet signal lines can be connected directly to the magnetics. Please refer to the Enclustra Module Pin Connection Guidelines [10] for details regarding the connection of Ethernet signals. 2.19.4 MDIO Address The MDIO address assigned to the Gigabit Ethernet PHY is 3.
USB 2.0 The Mars XU3 SoC module has an on-board USB 2.0 PHY connected to the MPSoC device, to the PS to I/O bank 502. The USB interface can be configured for USB host, USB device and USB On-The-Go (host and device capable) operations.
(PMU) - more information on the PMU is available in the Zynq UltraScale+ MPSoC Technical Reference Manual [19]. The RTC crystal pad input and crystal pad output are connected on the Mars XU3 SoC module to a 32.768 kHz oscillator.

3 Device Configuration Configuration Signals The PS of the MPSoC needs to be configured before the FPGA logic can be used. Xilinx Zynq devices need special boot images to boot from QSPI flash, eMMC flash or SD card. For more information, please refer to the Zynq UltraScale+ MPSoC Technical Reference Manual [19].
All configuration signals except for BOOT_MODE must be high impedance as soon as the device is released from reset. Violating this rule may damage the equipped MPSoC device, as well as other devices on the Mars XU3 SoC module. Pull-Up During Configuration The Pull-Up During Configuration signal (PUDC) is pulled to GND on the module;...

Power-on Reset Delay Override The power-on reset delay override MPSoC signal (POR_OVERRIDE) is pulled to GND on the module, setting the PL power-on delay time to the default standard time.
For details on the POR_OVERRIDE signal please refer to the Zynq UltraScale+ MPSoC Technical Reference Manual [19]. Boot Mode The boot mode can be selected via two signals available on the module connector. Table 30 describes the available boot modes on the Mars XU3 SoC module. BOOT BOOT Mode...
In the SD card boot mode the PS boots from the SD card located on the base board. There are two SD card boot modes available on the Mars XU3 SoC module. Please note that the SD boot mode with level shifter is currently not supported.
Certain Xilinx tools versions support QSPI flash programming via JTAG only when JTAG boot mode is used (unavailable on the Mars XU3 SoC module). For more information, please refer to the Xilinx documentation [19] and support. Alternatively, the QSPI flash can be programmed in u-boot or Linux by the SPI controller in the PS or from an SPI external master.
3.12 Enclustra Module Configuration Tool In combination with an Enclustra base board, the QSPI flash can be programmed using Enclustra Module Configuration Tool (MCT) [17]. For this method, a non-QSPI boot mode must be used during QSPI flash programming. The entire procedure is described in the reference design documentation, and is only avail- able starting with revision 2 modules.
4 I2C Communication Overview The I2C bus on the Mars XU3 SoC module is connected to the MPSoC device and to the EEPROM, and is available on the module connector. This allows external devices to read the module type and to connect more devices to the I2C bus.
An example demonstrating how to read the module information from the EEPROM memory is included in the Mars XU3 SoC module reference design. Warning! The secure EEPROM is for Enclustra use only. Any attempt to write data to the secure EEPROM causes the warranty to be rendered void. 4.4.1...
