Numbers in parentheses are for EPF81500A devices only.
Row-to-IOE Connections
Figure 11 illustrates the connection between row interconnect channels
and IOEs. An input signal from an IOE can drive two separate row
channels. When an IOE is used as an output, the signal is driven by an
n-to-1 multiplexer that selects the row channels. The size of the
multiplexer varies with the number of columns in a device. EPF81500A
devices use a 27-to-1 multiplexer; EPF81188A, EPF8820A, EPF8636A, and
EPF8452A devices use a 21-to-1 multiplexer; and EPF8282A and
EPF8282AV devices use a 13-to-1 multiplexer. Eight IOEs are connected to
each side of the row channels.
