TUSB8041: Can I get factory programmed VID/PID in the OTP?

Part Number: TUSB8041

Tool/software:

I generally order my MCUs pre flashed with at least a boot loader from the vendor.  Can I do the same with the TUSB8041?

It looks like I can preload an EEPROM with VID/PID amoung other things, so maybe a preloaded EEPROM is the correct path here?  But I don't need the EEPROM for other settings, after reading through the docs I think the OTP space is sufficient for my product needs.

  • Hi Jay:

      You can program PID/VID with efuse tool, TI can provide efuse tool  if you needed.

  • Right, but I don't want to manufacture 1000 hubs and then need to attach wires to all 1000 hubs before shipping product, and deal with all the costs and errors attaching those wires to each device brings and the QA associated with finding and fixing any errors that occur.  So the question is does TI offer a programming service so I can order the TUSB8041 with the OTP flashed from the 'factory', or do you know if a reseller like Digikey can flash the OTP of the TUSB8041 as part of their ordering / fulfillment process?  This way I can do statistical sample QA validation rather than having to touch each and every device on a programming/QA manufacturing line.


    If not, it looks like I can order EEPROM preflashed from Digikey, and a part that seems to match to the TUSB8041 would be the Microchip 24C02C (100 khz, 2kbit/256x8, I2C address 1010000).  However the TUSB8041 datasheet doesn't give an example eeprom circuit and the reference implementation BOMs I can find don't use the EEPROM option.  Can you confirm that the TUSB8041 and the Microchip 24C02C are a good match?
