an I2C link is running with a 500 kHz clock How long does it

an I2C link is running with a 500 kHz clock. How long does it take for a single message containing one data byte to be transmitted (ensuring that you calculate time for the complete message)?

       (a) 2 µs

       (b) 4 µs

       (c) 8 µs

       (d) 16 µs

       (e) None of (a) through (d) is the correct answer.

Solution

file size (b) / transfer speed (bps) = time (s).

So, 500khz=500000hz clock.

1byte=8bits,

so total time=8/500000 =16 micro sec.

So, d is the correct answer.
