5CEBA7F27C8N_Power Consumption for VREFB[3..8]AN0

Question

Hello,For 5CEBA7F27C8N FPGA, there are voltage reference pins as below.VREFB3AN0VREFB3BN0VREFB4AN0VREFB5AN0VREFB5BN0VREFB6AN0VREFB7AN0VREFB8AN0In 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, Page no: 13https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-v/cv_51002.pdfYou may also check: https://cdrdv2.intel.com/v1/dl/getContent/655051?explicitVersion=true&amp;fileName=cyc_c51008.pdfRegards,Fakhrul
