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,

no, 400 Kbps (400 kHz) maximal, as specified. Special fast I2C variant can achieve higher speed by using push-pull drivers, obviously the discussed IP doesn't provide it.

Still not clear what you want to achieve.

    Hi Frank,

    Thank you for the reply.

    You mentioned about the special fast I2C variant, where/how can I get access to this special fast I2C variant and will it run at a speed of 1Mhz.

    And if that special fast I2C is used in Stratic10 soc FPGA, will the open drain IO pads support speed of 1Mhz.

    Are there Open-Drain pads in Stratix 10 device that can run at 1Mhz.

    Can you provide detailed explanation on this.

    Regards,

    Kiran
