I/O Structure
I/O Blocks
The IOEs are located in I/O blocks around the periphery of the MAX II
device. There are up to seven IOEs per row I/O block (5 maximum in the
EPM240 device) and up to four IOEs per column I/O block. Each column
or row I/O block interfaces with its adjacent LAB and MultiTrack
interconnect to distribute signals throughout the device. The row I/O
blocks drive row, column, or DirectLink interconnects. The column I/O
blocks drive column interconnects.
Figure 2–20 shows how a row I/O block connects to the logic array.
