The Cyclone III device family IOE offers a range of programmable features for an I/O
pin. These features increase the flexibility of I/O utilization and provide an
alternative to reduce the usage of external discrete components to on-chip, such as a
pull-up resistor and a diode.
The output buffer for each Cyclone III device family I/O pin has a programmable
current strength control for certain I/O standards.
The LVTTL, LVCMOS, SSTL-2 Class I and II, SSTL-18 Class I and II, HSTL-18 Class I
and II, HSTL-15 Class I and II, and HSTL-12 Class I and II I/O standards have several
levels of current strength that you can control.
