Part Number: TUSB8042A
Other Parts Discussed in Thread: TUSB8041, TUSB8042,

Hello team

Currently my customer is using the TUSB8041 and will change it to TUSB8042.

And I have got some requests on the below.

Could you review and let me get your advice on those queries from customer?

IC : TUSB8042A

Application : Windows Tablet

1. Recommendation of Production Test to Check all the functions and internal default registers and EEPROM are okay to go to Market

--> currently I2C is connected to customer's application processor.

2. Reference Source Code for accessing to EEPROM and internal registers to read back the default setting and write down to value for the purpose of debugging if there's any issue during the R&D stage.

--> I2C is connected.

Please review and let me get your advice and guidance on those customer's queries.

Thanks and Best Regards

Hi Billy,

Please see the links below for EEPROM information and background on the transition from TUSB8041 to TUSB8042A

The customer can read back the default registers for the device and confirm that they match the datasheet. SMBUS address is defined in the datasheet. When the hub is in SMBUS mode (SMBUSz = 0), the hub will not connect until the cfgactive bit is set by the SMBUS host.
