5CEBA7F27C8N_Power Consumption for VREFB[3..8]AN0
Hello,
For 5CEBA7F27C8N FPGA, there are voltage reference pins as below.
VREFB3AN0
VREFB3BN0
VREFB4AN0
VREFB5AN0
VREFB5BN0
VREFB6AN0
VREFB7AN0
VREFB8AN0
In Pin Connection Guidelines(PCG-01014-3.2), it is mentioned that "when VREF pins are not used, you should connect them to either the VCCIO in the bank in which the pin resides or GND."
When these pins are connected to VCCIO of respective banks, will there be any current consumption on these pins? Please confirm.
Note: Attached below snapshot from pin connection guidelines for reference.

Hi ShivaKi,
The current consumption of a Cyclone V VREF pin is typically very minimal. You can check the maximum leakage current for the IO pins , is 30uA,
