Dedicated Fast I/O Pins
APEX 20KE devices incorporate an enhancement to support bidirectional
pins with high internal fanout such as PCI control signals. These pins are
called Dedicated Fast I/O pins (FAST1, FAST2, FAST3, and FAST4) and
replace dedicated inputs. These pins can be used for fast clock, clear, or
high fanout logic signal distribution. They also can drive out. The
Dedicated Fast I/O pin data output and tri-state control are driven by
local interconnect from the adjacent MegaLAB for high speed.
Row Interconnect
Column Interconnect
Each IOE can drive column interconnect. In APEX 20KE devices,
IOEs can also drive FastRow interconnect. Each IOE data
and OE signal is driven by local interconnect.
Any LE or ESB can drive
a column pin through a
row, column, and MegaLAB
interconnect.
