Notes to
(1) This represents the maximum number of DQ pins (including parity and data mask pins) connected to the DQS bus network with single-ended
(2) The DM pin can be supported if the differential DQS is not used and the group does not have additional signals.
(3) Two ×4 DQ/DQS groups are stitched together to create a ×8/×9 group, so there are a total of 12 pins in this group.
(4) Four ×4 DQ/DQS groups are stitched together to create a ×16/×18 group.
(5) Eight ×4 DQ/DQS groups are stitched together to create a ×32/×36 group.

Device
DQS signaling. If you are using differential or complementary DQS signaling, the maximum number of data-per-group decreases by one. This
number may vary per DQ/DQS group in a particular device. For the DDR, DDR2, and DDR3 interface, the number of pins is further reduced for
interfaces larger than ×8 due to the need of one DQS pin for each ×8 group. Check with the pin table for the accurate number per group.

DQSn Support
The Arria II GX device supports DQ and DQS signals with DQ bus modes of ×4,
×8/×9, ×16/×18, or ×32/×36. The DDR, DDR2, and DDR3 interfaces use one DQS pin
for each ×8 group; for example, an interface with a ×72 DDR2 DIMM needs nine DQS
pins. When any of these pins are not used for memory interfacing, you can use them
as user I/Os. In addition, you can use any DQSn or CQn pins not used for clocking as
DQ (data) pins.
