Table 35. ORT8850H Pins That Are Unused in ORT8850L
Users should avoid using these pins if they plan to migrate their ORT8850H design to an ORT8850L.
Package Pinouts
Table 36 provides the package pin and pin function for the ORT8850 FPSC and packages. The bond pad name is
identied in the PIO nomenclature used in the
ispLEVER design editor. The Bank column provides information as
to which output voltage level bank the given pin is in. The Group column provides information as to the group of
pins the given pin is in. This is used to show which VREF pin is used to provide the reference voltage for single-
ended limited-swing I/Os. If none of these buffer types (such as SSTL, GTL, HSTL) are used in a given group, then
the VREF pin is available as an I/O pin.
When the number of FPGA bond pads exceeds the number of package pins, bond pads are unused. When the
number of package pins exceeds the number of bond pads, package pins are left unconnected (no connects).
When a package pin is to be left as a no connect for a specic die, it is indicated as a note in the device column for
the FPGA. The tables provide no information on unused pads.
