16-Segment LED Display (D30)
The LatticeECP3 general-purpose I/O pins are connected to a 16-segment display, as shown in Table 33. These
pins can be driven low to illuminate the display segments.

Logic Analyzer Connector and Test Points
For debugging purposes, all unused LatticeECP3 I/Os are connected to connectors/headers for debugging a
design using test equipment such as logic analyzers or scopes.
Logic Analyzer Connector
An on-board Mictor connector is connected to many LatticeECP3 I/Os to make it easy to use a logic analyzer for
debugging the FPGA design. The Mictor connector pins are connected to different I/O banks with different Vccio
voltages. Users may need to configure the threshold voltage of the logic analyzer pod to match the signals being
monitored. Other than connecting to the Mictor connector, these LatticeECP3 pins are also connected to two stan-
dard 100-mil pitch headers for use with logic analyzers or scopes that do not support Mictor connection. Table 34
shows the LatticeECP3 pin connections to the Mictor connector and the two headers.
