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

When planning I/O bank usage for Cyclone® V 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.

Examples:

  • VCCPD3B is connected to 2.5 V—VCCIO pins for banks 3B and 4A can be connected 1.2 V, 1.25 V, 1.35 V, 1.5 V, 1.8 V, or 2.5 V.
  • VCCPD3B is connected to 3.0 V—VCCIO pins for banks 3B and 4A must be connected to 3.0 V.
