MP5475 very first startup with Artix US+

[r.eckert]

Hello,

I referring to the reference design for a high power Artix US+ 10P.

Artix UltraScale+ AU10P/15P Minimum Rails – Highest Power Reference Design

My questions is how is the very first startup of the MP5475 handled? Are the default values are used until the memory is flashed? The problem is that the default buck output values are 1.1V but the max VCCINT value of the FPGA is 1.0V. So how is the very first startup of the PCB is handled so that the FPGA is not damaged, the MP5475 can be programmed and after that the FPGA can be flasehd?

Thank you.

Hi r.eckert,

The initial use of MP5475 can be programmed with the GUI with a laptop on the EVB. Once engineering prototypes are done, we can assign a custom suffix code which will use the right settings for your Artix FPGA for production designs.

Thanks,

George
