    ECP5 Device This board features an ECP5 FPGA in a 756-ball caBGA with a 1.1 V core supply. A complete description of this device can be found in DS1044, ECP5 Family Data Sheet.
  • Page 4 Expansion Card on CN1 Connector (Left) 0100 Expansion Card on CN2 Connector (Right) SW7 includes the ECP5 CFG pins (1=Up, 0=Down) which allow the configuration mode of the ECP5 to be selected. Switches are the right side of SW7 where SW7[1]=CFG0, SW7[2]=CFG1, SW7[3]=CFG2...
  • Page 5 A Micron N25Q128A device is populated on-board. The Serial SPI Flash memory device can be configured easily via the ECP5 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 6 5. Click OK in the Device Properties dialog box. You will return to the main configuration screen. 6. Using SW6 set the ECP5 CFG pins to 010. 7. From the main programming window, select Go from the top toolbar. This begins the SPI Serial Flash program-...
  • Page 7 (See Appendix B, "Clock Generation" and "LPDDR3" sheets) The ECP5 PCI Express Board allows for several clock source options. Some of these options are controlled via the ispClock5304 programmable clock manager device. The clock manager will be supplied by a 54 MHz clock on- board oscillator or an external clock source.
  • Page 8 ECP5 PCI Express Board User’s Guide FPGA Test Pins (See Appendix B, "ECP5 Config" and "LEDs and Switches" sheets) General Purpose DIP Switches General purpose FPGA pins are available for user applications. FPGA pins are connected to switch SW4, SW7 with a piano style DIP switch.
