5.4.3. Guideline: Ensure Compatible VCCIO and VCCPD Voltage in the Same Bank

When planning I/O bank usage for Arria® V GX, GT, SX, and ST devices, you must ensure the VCCIO voltage is compatible with the VCCPD voltage of the same bank. Some banks may share the same VCCPD power pin. This limits the possible VCCIO voltages that can be used on banks that share VCCPD power pins.


  • VCCPD4BCD is connected to 2.5 V—VCCIO pins for banks 4B, 4C, and 4D can be connected 1.2 V, 1.25 V, 1.35 V, 1.5 V, 1.8 V, or 2.5 V.
  • VCCPD4BCD is connected to 3.0 V—VCCIO pins for banks 4B, 4C, and 4D must be connected to 3.0 V.
