Power Pin Connections and Power Supplies

Cyclone® 10 GX devices require various voltage supplies depending on your design requirements. To verify the core voltage, PLL digital power supply, programmable technology voltage, and other voltage supply levels, refer to the Cyclone® 10 GX Device Datasheet.

Cyclone® 10 GX devices support a wide range of industry I/O standards, such as the following VCCIO voltage levels:

  • 3.0 V (only on 3.0 V I/O bank)
  • 2.5 V (only on 3.0 V I/O bank)
  • 1.8 V
  • 1.5 V
  • 1.35 V
  • 1.25 V
  • 1.2 V
Note: The device output pins do not meet the I/O standard specifications if the VCCIO level is out of the recommended operating range for the I/O standard.

Voltage reference (VREF) pins serve as voltage references for certain I/O standards. The VREF pin is used mainly for a voltage bias and does not source or sink much current. The voltage can be created with a regulator or a resistor divider network.

For more information about VCCIO voltages and VREF pins for different I/O banks, refer to “Selectable I/O Standards and Flexible I/O Banks” chapter.

The VREFP_ADC pin is not a power supply pin. It provides the reference voltage for the ADC for the voltage sensor. For better voltage sensor performance, connect VREFP_ADC to an external reference 1.25 V source. Connecting VREFP_ADC to GND actives an on-chip reference source.

Number Done? Checklist Item
1   Connect all power pins correctly as specified in the Cyclone 10 GX Device Family Pin Connection Guidelines.
2   Connect VCCIO pins and VREF pins to support each bank’s I/O standards.
3   Explore unique requirements for FPGA power pins or other power pins on your board, and determine which devices on your board can share a power rail.
4   Follow the suggested power supply sharing and isolation guidance, and the specific guidelines for each pin in the Cyclone 10 GX Device Family Pin Connection Guidelines.
