TFP401A: TFP401A - I2C and EEPROM

Part Number: TFP401A
Other Parts Discussed in Thread: TFP403, TFP401, TFP501

Hi,

document SLLA134 shows DDC_SCL/SDZ/SA and PROM_SCL/SDA but none of them are on the TFP403/401.

Those pins are used for something else and/or there are no such signals.

Can you please explain.

Thanks

Rick

    Hi Rick,

    That document is for the TFP501/403, not for the TFP401.

    In the TFP403 datasheet, the pin description for these pins says "Reserved. See TFP501 data sheet for intended future use."

    In the TFP501 datasheet, these pins are in fact DDC_SCL/SDZ/SA and PROM_SCL/SDA.

    Regards,
    I.K.
