DS90UB926Q-Q1:Maximum number of I2C connections

Part Number: DS90UB926Q-Q1

Hi team,

I want to use the deserializer board as an I2C master to control devices on the serializer board.
How many devices can be controlled?
Is it theoretically possible to connect up to 112 nodes of the I2C standard?

Best,
Ryu.

    Hi Ryu,

    Up to eight peripheral devices can be controlled by the 926.

    In theory, yes. In practice, however, the number of node connections is limited by the total bus capacitance of 400 pF. Would you be able to provide me with more details about your design and what you are looking to accomplish?

    Best,
