Pci Express Power Interface; Programming/Fpga Configuration; Ispvm Download Interface - Lattice Semiconductor LatticeECP2M PCI Express x4 User Manual

Lattice Semiconductor
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 1. Board Power Supply Fuses (see Appendix A, Figure 6)
Table 2. Board Power Supply Indicators (see Appendix A, Figure 6)
External power can be alternatively connected rather than the wall transformer power pack.

PCI Express Power Interface

Power can be sourced to the board via the PCB edge finger (CN1). This interface allows the user to provide power
from a PCI Express host board.
Programming/FPGA Configuration
(see Appendix A, Figure 8)
A programming header is provided on the evaluation board, providing access to the LatticeECP2M JTAG port.

ispVM Download Interface

J8 is an 10-pin JTAG connector, providing access to the LatticeECP2M JTAG port. It can be used in conjunction
with the ispVM System software and Lattice USB download cable to program and control the device.
