Package Pinouts
Table 18 provides the number of user-programmable I/Os available for each available package.
Table 19 provides
the package pin and pin function for the ORLI10G 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 volt-
age 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.
Table 18. ORCA Programmable I/Os Summary
The built-in MicroProcessor Interface (MPI) cannot be fully utilized in the 680-pin PBGA package because the
implementation of the XGMII interface limits the number of available address and data pins.
As shown in the Pair columns in
Table 19, differential pairs and physical locations are numbered within each bank
(e.g., L19C_A0 is the nineteenth pair in an associated bank). A C indicates complementary differential, whereas a
T indicates true differential. An _A0 indicates the physical location of adjacent balls in either the horizontal or verti-
cal direction. Other physical indicators are as follows:
_A1 indicates one ball between pairs.
_A2 indicates two balls between pairs.
_D0 indicates balls are diagonally adjacent.
_D1 indicates balls are diagonally adjacent separated by one physical ball.
VREF pins, shown in the Pin Description column in
Table 19, are associated to the bank and group
(e.g., VREF_TL_01 is the VREF for group one of the Top Left (TL) bank).
