MAX10 seriese VREF connection

[Kenji_Shimada]

I use 10M02SCU169I7G.
10M02SCU169I7G has no ADC pin and I don't use diffarencial pin.
How to treat Vref pin? (connect to GND or connect to VCCIO?)

Hi,

For the single-ended I/O standard, you no need to connect the Vref pin to voltage. Based on the Pin Connection Guidelines, which you can refer to below link, if you are not using the VREF pins, you can connect unused pins as defined in the Intel® Quartus® Prime software.
