Altera Stratix V FPGA (P/N: 5SGSMD8N2F45C2L)

This part is supplied via two separate power rails (1.8V and 3.3V). The 1.8V rail supplies the VCCINT and VCCI02 pins, and the 3.3V supplies the the VCCI01 pins. The 1.8V rail comes up to voltage in ...

Hi,


Thank you for reaching out to Intel FPGA Community.


Before I answered your question, can I confirm on the symbol, is it VCC you refer as VCCINT? This is because when I checked the datasheet, the absolute maximum value for VCC of Stratix V Device is 1.35V. Based on your question, you mentioned you supply it with 1.8V.


Can you confirm this first?

    Hello,

    Apologies for the confusion. The VCC pins are receiving 0.85V, and the 1.8V rail is feeding VCCIO8A through VCCIO8B.

    Thanks.
