Table 6. LED Pin Assignments
In addition to the discrete chip LEDs there is a single 7-segment display. Like the discrete LEDs, a V
cause a segment to illuminate. The segment order is defined in the Lumex LDS-A304RI Data Sheet.
Table 7. 7-Segment LED Pin Assignments
Switches
The evaluation board provides a set of eight simple toggle switches at the southwest edge of the board. The silk-
screen calls out the alphanumeric location of the I/O on the FPGA. The switch, when in the up position, is pulled to
VCCIO6 through a 10K resistor. When in the down position, the switch is tied to ground.

Oscillator and Clock Inputs
FPGA designs are almost without exception created with logic synchronous to some reference frequency. The
LatticeXP2 Standard Evaluation Board provides a built-in oscillator that provides a reference frequency for syn-
chronous FPGA logic. Reference frequencies can be applied to other LatticeXP2 clock inputs as well.
The LatticeXP2 board provides a low-voltage (3.3V) DIP oscillator. The oscillator is installed in a 14-pin DIP socket.
The socket permits the use of either a half-size or full-size DIP oscillator.
