I want to know CYUSB2304's I2C AC specs.

However, there is no description of AC specs in "HX3 USB 3.0 Hub datasheet(001-73643 Rev.*R)".

I think it is equivalent to "PSoC Creator Component I2C Master/Multi Master/Slave".

Is there any problem with AC Characteristics (UDB Implementation)?

Hello,

Thank you for using Cypress Developer Community.

HX3 supports I2C with the standard mode (100kHz) and the fast mode (400kHz) frequency as per datasheet.

Do you need more information? Please clarify.

FYI: As of 3rd Sept. 2019, latest HX3 datasheet is 001-73643 Rev. *T. Kindly refer to the latest datasheet.

Best regards,

Hirotaka Takayama

Hi

Thank you for response.

I understood to refer to 100kHz and 400kHz in "PSoC Creator Component I2C Master/Multi Master/Slave".

Thank you very much.

Hello,

Just in case, I will follow-up.

I do not refer to the PSoC document.

I am just saying about HX3 datasheet and I2C information is described in it.

Best regards,
