5.2.2. Guideline: Use the Same VCCPD for All I/O Banks in a Group

One VCCPD is shared in a group of I/O banks. If one I/O bank in a group uses 3.0 V VCCPD, other I/O banks in the same group must also use 3.0 V VCCPD.

The I/O banks with the same bank number form a group. For example, I/O banks 7A, 7B, 7C, and 7D form a group and share the same VCCPD. This sharing is applicable to all I/O banks, with the following exceptions:

  • I/O banks 3A and 3B form a group with one VCCPD.
  • I/O banks 3C, 3D, and 3E (if available) form another group with its own VCCPD.

If you are using an output or bidirectional pin with the 3.3 V LVTTL or 3.3 V LVCMOS I/O standard, you must adhere to this restriction manually with location assignments.
