ECP5 PCI Express Board User’s Guide
Caution: The ECP5 PCI Express Board contains ESD-sensitive components. ESD safe practices should be fol-
lowed while handling and using the evaluation board.
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.
Note: The connections referenced in this document refer to the LFE5UM-85F-7MG756BC device.
Applying Power to the Board
The ECP5 PCI Express 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 12 V DC input power source is fused with a surface mounted fuse, as noted in Table 1.
Table 1. Board Power Supply Fuses (See Appendix B, "Power Supplies" sheet)
The board may be plugged into a host PC. Only plug the board into a PCI Express slot when the system is powered
off. Once inserted, the PC can be safely powered on.
Using the evaluation board outside of a PC chassis supply requires the factory-supplied wall supply module. Use of
other supplies is not suggested.
Figure 2. Power Distribution Scheme (See Appendix B, "Power Supplies" sheet)
Programming/FPGA Configuration
The ECP5 PCI Express Board has a built-in download controller for programming the ECP5 FPGA. The built-in
module consists of a USB Type-B connector and a USB UART device. To use the built-in down- load cable, simply
connect a standard USB cable (a USB-B to USB-A cable is included with the ECP5 PCI Express Board) from J5 to

function, making the built-in cable available for use with the Diamond Programmer software.
Diamond Programmer Requirements
Note: This board includes the built-in download module and only requires the USB cable included with the board.
After initial board setup, use the following procedure to program the board. Instructions assume that Diamond Pro-
grammer software has been installed on a local PC.
Requirements:
• PC with Diamond Programmer 3.2 (or later) programming software, installed with appropriate drivers (USB driver
for USB cable).
Note: An option to install these drivers is included as part of the Diamond Programmer setup.

Figure 4. ECP5 Configuration Pin (CFG pins)
Figure 5. ECP5 Status LEDs and Push-button Controls
The LEDs indicate the configuration status of the ECP5 FPGA.
• D10 (red) illuminated indicates that programming was aborted or reinitialized, driving the INITN output low.
• D11 (green) illuminated indicates the successful completion of configuration by releasing the open collector
DONE output pin.
PROGRAMN and GSRN
These push-button switches assert/de-assert the logic levels on PROGRAMN (S2) and GSRN (S1). Depress- ing
the button drives a logic level “0” to the device.
Programming Serial SPI Flash Memory
A serial SPI (16-pin TSSOP, 128Mb) Flash memory device (U52) is on-board for non-volatile configuration memory
storage. 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.
1. Connect the ECP5 PCI Express Board.
2. Scan the board or select the ECP5UM-85F device.
3. From the Edit pull down menu select Device Properties. Set the Access mode to SPI Flash Background Pro-
gramming and Operation to SPI Flash Erase, Program, Verify.

On-Board Clock Capabilities (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. The LPDDR3 clock will be supplied directly from a 100 MHz on board
oscillator.
Table 2. Clock Sources
SERDES
The ECP5 based SERDES FPGA is utilized on the board for several purposes. The SERDES block is provisioned
to provide a single, full-duplex PCI Express channel. The high-speed signals are connected to the PCI Express
edge connection.

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. The switches are connected to logic level 0 when Down, logic level 1 when Up.
Switch position 1 is indicated with a dot. Switch SW4 logic 1 is 2.5V. Switch SW4 logic 1 is 2.5V. The user must pro-
gram these inputs to be the LVCMOS25 or LVCMOS33 type in the design.

General Purpose LEDs (See Appendix B, "LEDs and Switches" sheet)
The LEDs provided on the ECP5 PCI Express 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. Table 6 shows the LED and associated FPGA pins. These pins are within an I/O bank connected to
2.5 V and the user should program these to be LVCMOS25 type outputs in the design.
Table 4. LED Definitions
LPDDR3 Memory Device (See Appendix B, "LPDDR" sheet)
• The ECP5 PCI Express Board is equipped with a LPDDR3 memory device (1.2 V, 64 Mb/x32, 96-ball FBGA,
1600 MHz) such as the Micron EDF8132A1MC device.
• The LPDDR3 memory is limited to a 16-bit wide memory controller interface.
• A 100-MHz on-board clock oscillator is available to provide a LPDDR3 reference clock.

Power Measurements (See Appendix B, "ECP5 Power" sheet)
The ECP5 PCI Express Board allows for easy power measurements with a multi-meter of the ECP5 device. The
ECP5 power rails are isolated and can be measured by measuring the voltage across power resistors.
Figure 9. ECP5 Power Measurements
PMOD (See Appendix B, "ECP5 Config" sheet)
The ECP5 connects to a PMOD connector J3. To isolate the PVMOD connector from the FTDI device set all SW5
switches to 1 (Up=1).
