Number Done? Checklist Item
1   Connect all power pins correctly as specified in the Intel Agilex® 7 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 Intel Agilex® 7 Device Family Pin Connection Guidelines.
5   Refer to AN 692: Power Sequencing Considerations for Intel® Cyclone® 10 GX, Intel® Arria® 10, Intel® Stratix® 10, and Intel Agilex® 7 Devices to understand the power sequencing design requirements.

Intel Agilex® 7 devices require various voltage supplies depending on your design requirements.

Intel Agilex® 7 devices support a wide range of industry I/O standards. 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.

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 the VREFP_ADC pin to GND. Connecting the VREFP_ADC pin to GND actives an on-chip reference source.
