Lattice Semiconductor
Programmable I/O Cells (PIC)
Each PIC contains two PIOs connected to their respective sysIO buffers as shown in Figure 2-25. The PIO Block
supplies the output data (DO) and the tri-state control signal (TO) to the sysIO buffer and receives input from the
buffer. Table 2-11 provides the PIO signal list.
Figure 2-25. PIC Diagram
Two adjacent PIOs can be joined to provide a differential I/O pair (labeled as “T” and “C”) as shown in Figure 2-25.
The PAD Labels “T” and “C” distinguish the two PIOs. Approximately 50% of the PIO pairs on the left and right
edges of the device can be configured as true LVDS outputs. All I/O pairs can operate as inputs.
