LatticeECP3 Device
This board features a LatticeECP3 FPGA with a 1.2V core supply. It can accommodate all pin compatible
LatticeECP3 devices in the 672-ball fpBGA (1mm pitch) package. A complete description of this device can be
found in the LatticeECP3 Family Data Sheet on the Lattice website at www.latticesemi.com.
Note: The connections referenced in this document refer to the LFE3-95EA-FN672 device. Available I/Os and
associated sysI/O™ banks may differ for other densities within this device family.
Applying Power to the Board
The LatticeECP3 PCI Express Solutions Board is ready to power on. The board can be supplied with power from
an AC wall-type transformer power supply shipped with the board. Or it can be supplied from a benchtop supply via
terminal screw connections. It also has provisions to be supplied from the PCI Express edge fingers from a host
board.
To supply power from the factory-supplied wall transformer, simply connect the output connection of the power cord
to J1 and plug the wall-transformer into an AC wall-outlet.
Power Supplies
(see Appendix A, Figure 21)
The evaluation board incorporates an alternate scheme to provide power to the board. The board is equipped to
accept a main supply via the TB1 connection. This connection is provided to use with a benchtop supply adjusted
to provide a nominal +12V DC.
All input power sources and on-board power supplies are fused with surface-mounted fuses and have green LEDs
to indicate power GOOD status of the intermediate supplies

Table 2. Board Power Supply Indicators (see Appendix A, Figure 21)
External power can be alternatively connected rather than the wall transformer power pack.
