    2.15.2 Signal Description Please refer to the Mercury ZX1 SoC Module FPGA Pinout Excel Sheet [4] for detailed information on the DDR3 SDRAM connections. 2.15.3 Termination Warning! No external termination is implemented on the Mercury ZX1 SoC module. Therefore, it is strongly recommended to enable the on-die termination (ODT) feature of the DDR3 SDRAM device.

  • Page 31: Ddr3 Low Voltage Operation

    2.16 DDR3 SDRAM (PL) The DDR3 SDRAM connected to the PL on the Mercury ZX1 SoC module is operated at 1.35 V (low power mode) or at 1.5 V, depending on a selection signal. The DDR bus width is 16-bit.

  • Page 33: Ddr3 Low Voltage Operation

    Table 26 describes the memory availability and configuration on the Mercury ZX1 SoC module. As there is one QSPI flash chip equipped on the Mercury ZX1 SoC module, type “single” must be selected when programming the flash from Vivado tools.

  • Page 34: Signal Description

    QSPI flash from an external master. Note that MIO pins 2-6 pins are shared between NAND flash and QSPI flash on the Mercury ZX1 SoC mod- ule, therefore only of the two memories may be used at once. However, it is possible to switch between them at runtime.

  • Page 35: Nand Flash

    Please refer to the NAND flash memory device datasheet to extract the required parameter values. Refer- ence values to be used in Vivado are given in Table 28. The indicated parameter values may be used for booting from NAND flash memory on the Mercury ZX1 SoC module.

  • Page 36: Gigabit Ethernet

    Please note that Xilinx recommends operation at 1.8 V/2.5 V for the RGMII interface for the MIO pins [18]. Enclustra tests have shown that the RGMII is functional with a 3.3 V I/O voltage on the MIO pins, as long as the I/O voltage configured in Vivado matches the applied I/O voltage.

  • Page 37: External Connectivity

    Table 30: Gigabit Ethernet Signal Description 2.20.3 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. 2.20.4 MDIO Address The MDIO address assigned to the Gigabit Ethernet PHY is 3.

  • Page 38: Dual Fast Ethernet

    I/Os via MII interface. On Mercury ZX1 SoC modules revision 1 the Fast Ethernet ports are not enabled when DDR3 SDRAM is operated in low power mode. This is because the Ethernet ports are fed by the same supply as the DDR3 memory and require a voltage of 1.5 V to work properly.

  • Page 39: External Connectivity

    MHz. 2.22 USB 2.0 The Mercury ZX1 SoC module has an on-board USB 2.0 PHY connected to the SoC device. The USB interface can be configured for USB host, USB device and USB On-The-Go (host and device capable) operations. 2.22.1 USB PHY Type Table 34 describes the equipped USB PHY device type on the Mercury ZX1 SoC module.

    A real-time clock is connected to the I2C bus. The RTC features a battery-buffered 128 bytes user SRAM and a temperature sensor. See Section 4 for details on the I2C bus on the Mercury ZX1 SoC module. VBAT pin of the RTC is connected to VCC_BAT on the module connector, and can be connected directly to a 3 V battery.

  • Page 41: Device Configuration

    3 Device Configuration Configuration Signals The PS of the SoC needs to be configured before the FPGA logic can be used. Xilinx Zynq devices need special boot images to boot from QSPI flash or SD card. For more information, please refer to the Xilinx Zynq-7000: Concepts, Tools, and Techniques document [20].

  • Page 42: Pull-Up During Configuration

    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 SoC device, as well as other devices on the Mercury ZX1 SoC module. Pull-Up During Configuration The Pull-Up During Configuration signal (PUDC) is pulled to ground via a 1 k resistor during FPGA config- uration, and connected to an FPGA signal after this process is done.

  • Page 43: Boot Mode

    For details on the PUDC signal please refer to the Zynq-7000 All Programmable SoC Technical Reference Manual [18]. Boot Mode The boot mode can be selected via two signals available on the module connector. Table 38 describes the available boot modes on the Mercury ZX1 SoC module.
