Hi support team,

is the EEPROM absolutely necessary or can it be left out?

I thought that if you can load the firmware via USB-C or via I2C (MCU), you could omit the EEPROM?

Please give me a clear statement.

Thank you

Hi Thomas,

Yes, you can delete the EEPROM, but need to use the MCU/HUB to load the firmware via I2C2, and also need to set the TVSP to Index1, 3, 5, 7.

Your schematic diagram should be like:

For the USB-C update, it only can work when the EEPROM is exist, and need to set the TVSP to Index 8, then you can update the EEPROM firmware via the USB-C. Thank you.

Best Regards,

Kuno

Hi Kuno,

so I need at least one of these two, either an EEPROM or a micrcontroller right? The chip itself has no internal memory?

Best regards,

Thomas

Which MCU would you recommend?

hI Thomas,

Yes, you need an EEPROM or a MCU or a HUB is ok, the device have the internal memory, but only save the original function, need to update firmware to achieve the full function. And sorry, I am not familiar with the MCU, but as long as it can have the IIC communication is ok.

Best Regards,

Kuno
