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...

Regular ContributorHi
Sorry to mention that the Stratix10 only supports up to Fast Mode of the I2c protocol.
For the Stratix10 I2C controller maximum speed is up to 400Khz.
This is mentioned in the Stratix10 TRM :

It is the same if you are using the I2C Host IP :

Occasional ContributorHi Jingyang Teh,
Thank you for the answer.
If we port ASIC verified I2C (our own I2C module, which can run at 1.3Mhz) to stratix 10 FPGA then will the IO's support the same speed as ASIC (1.3Mhz) or will it be restricted to 400Khz.
Regards,
Kiran
