Summary of Contents for Lattice Semiconductor ECP5-5G

  • Page 1 ECP5-5G™ Versa Development Board User Guide EB103 Version 1.2, January 2016...
  • Page 2 The ECP5-5G Versa Development Board is part of the ECP5-5G Versa Development Kit. The guide is intended to be referenced in conjunction with demo user guides to demonstrate the ECP5-5G FPGA.

    Note: The connections referenced in this document refer to the LFE5UM5G-45F-8BG381C device. Applying Power to the Board The ECP5-5G Versa Development Board is ready to power on. The board can be supplied with power from a PCI Express host system or standalone with an external wall power module.

    The built-in module consists of a USB Type-B connector and a USB UART device. To use the built-in download cable, simply connect a standard USB cable (a USB-B to USB-A cable is included with the ECP5-5G Versa Devel- opment Kit) from J2 to your PC (with Diamond programming software installed). The USB hub on the PC will detect the addition of the USB function, making the built-in cable available for use with the Diamond programming soft- ware.

  • Page 5: Setting The Configuration Mode

    Diamond Programmer software connected to the Development board via a standard mini-USB cable. Refer to the ECP5-5G Versa Development Kit Quick Start Guide (QS039) for more details. Once the programming software is installed and the USB cable is connected to the board, the programmable devices can be programmed.
  • Page 6 Figure 6. ECP5-5G Status LEDs and Push-button Controls The LEDs indicate the configuration status of the ECP5-5G FPGA. • D17 (red) illuminated indicates that programming was aborted or reinitialized, driving the INITN output low. • D20 (green) illuminated indicates the successful completion of configuration by releasing the open collector DONE output pin.

  • Page 7: Programn And Gsrn

    A Micron N25Q128A device is populated on-board. The Serial SPI Flash memory device can be configured easily via the ECP5-5G JTAG port. This mode enables the FPGA to be programmed at power-up or assertion of PROGRAMN with a bitstream stored in the memory device.
  • Page 8 7. From the main programming window, select Program from the top toolbar. This begins the SPI Serial Flash programming. Note that the SPI Flash Background Programming operation is only possible when the ECP5-5G device is either erased or the active design has the MASTER_SPI_PORT mode enabled. For more details see...

  • Page 9: On-Board Clock Capabilities

    (See Appendix A, Sheet 9, Figure 21 - Reference Clock Generator) The ECP5-5G Versa Development Board allows for several clock source options. Some of these options are con- trolled via the ispClock5406D programmable clock manager device. The ispClock5406D enables the reference clock from the PCI Express interface to provide a reference clock to the SERDES.

  • Page 10: General Purpose Clock Source

    The PCI Express add-in card specification requires add-in boards to include capabilities to tell the host of its pres- ence. The ECP5-5G Versa Development Board allows this optional connection via a board jumper. Using the board with a PCI Express host requires the setting shown in Figure 10 below.

    Figure 12 shows the switches. Note the silk marking associated with SW3-7 is incorrect in revision B, SW3-7 is mapped to K19, per Table 7. Figure 11. ECP5-5G Versa Development Board LEDs and Switches The designated pins are connected according to Table 7.

  • Page 12: General Purpose Leds

    (See Appendix A, Sheet 8, Figure 20 - LEDs and Switches) The LEDs provided on the ECP5-5G Versa Development Board are connected to general purpose FPGA I/Os. These LEDs provide status for user designs and must be included in the design. The LEDs illuminate when the FPGA output is driven LOW.
