Hello,

Max V does not have dedicated I2C slaves. If you'd like to use it, you will have to develop controller inside of the FPGA. As for reference design, you can refer to Intel® FPGA Design Examples if we have reference design of it.

Thanks.

The question is more on the hardware connection of the MaxV as the handbook does not have any informtaion on the following:

1) Can the I2C be connected to any I/O pins?

2) The master is a I2C, 5V. The handbook mentioned that Max V can be 5V tolerant with an external resistors and clamped diode. Is there any reference design for this? If not, is it a voltage divider resistors to provide 3.3V to Max V? I managed to find the application note for the 5V tolerant. Is there any recommended external clamping diode?

    Hello,

    I think I have answered this on my previous response. Can you elaborate your concern?

    Thank you.
