Stratix 10 I2C IP Maximum speed of Operation

Hi, I would be using an I2C IP on the Stratix10 FPGA. What is the maximum speed of operation of this I2C IP. Is it interns of Giga or Megha Hertz would like to know the exact frequency range the I...

Hi, you are above referring to I2C interface of Stratix 10 Hard Processor. It's maximal speed is specified in Technical Reference Manual with 400 Kbps.

Generally, what's the idea behind bridging HPS I2C to AVMM master in your design? According to user guide, Intel FPGA I2C Agent to Avalon-MM Host Bridge Core is specifically intended to drive flash memory. Also this core is limited to 400 Kbps speed.

Gbps speed is simply impossible by nature of the I2C interface as open drain bus with asynchronous clock and arbitration

    Hi FvM,

    Thank you.

    It's not in gigahertz, my question should be will the I2C be working at some meghahertz speed, if so what's that speed.

    Regards,
