TUSB8041: How to program EEPROM for multi-level hub

Zhang Peng
Prodigy 35 points
Part Number: TUSB8041

Tool/software:

The current design requirement is to design a 10 port hub, which uses three tusb8041 chips. The second and third tusb8041 chips are respectively connected to the two downstream ports of the first chip. Now I want to program EEPROM of these hubs separately. How do I determine which hub EEPROM I am programming when using the tool?

    Hi Peng:

         It's better to program EEPROM  separately before soldering to the board.

        It you already soldering all EEPROMs to the board, only leave pullup on SDA/SCL for the hub you are going to do EEPROM and remove the pullups on SCL/SDA for the other two hub.

       Did I answer your questions?

    Best
