Notes to Table 7–3:
(1) Each side of the device in these packages has four remaining ×8/×9 groups. You can combine them for the write
side (only) if you want to keep the ×36 QDR II+/QDR II SRAM interface on one side of the device. You must change
the Memory Interface Data Group default assignment from the default 18 to 9 in this case.
(2) This device supports ×36 DQS/DQ groups on the top and bottom I/O banks natively.
(3) Although it is possible to combine the ×16/×18 DQS/DQ groups from I/O banks 1A and 1C, 2A and 2C, 5A and 5C,
and 6A and 6C, Altera does not recommend this due to the size of the package. Similarly, crossing a bank number
(for example, combining groups from I/O banks 6C and 5C) is not supported in this package.
