I/O Blocks
1
The IOEs are located in I/O blocks around the periphery of the MAX V device. There
are up to seven IOEs per row I/O block 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.
5M40Z, 5M80Z, 5M160Z, and 5M240Z devices have a maximum of five IOEs per row
I/O block.

Note to
(1) Each of the seven IOEs in the row I/O block can have one data_out or fast_out output, one OE output, and
one data_in input.
