    No, that is not true.

    With careful design, you can get over 12 feet; a poor design won't even manage 12 feet.

    There is no specific distance limit; you have to look at the other parameters - capacitance, in particular...

    To the OP: Note that this has nothing to do with Keil nor the 8051 - get the I2C specification and study it!
