Package Information
Package Pinouts
Table 32 provides the package pin and pin function for the ORT82G5 FPSC and packages. The bond pad name is
identied in the PIO nomenclature used in the ispLEVER System software design editor. The Bank column pro-
vides 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.
As shown in the pair columns in Table 32, 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 ver-
tical 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 32, are associated to the bank and group (e.g.,
VREF_TL_01 is the VREF for group one of the Top Left (TL) bank.t
