At 100 kbit/s. At other bit rates this value is inversely proportional to the bit-rate of 100 kbit/s.
Determined by the external bus-line capacitance and the external bus-line pull-resistor, this must be < 1

Spikes on the SDA and SCL lines with a duration of less than 3 t
CLK
will be filtered out. Maximum capacitance on
bus-lines SDA and SCL = 400 pF.

CLK
= 1/f
CLK
= one oscillator clock period at pin XTAL1. For 62 ns < t
CLK
< 285 ns (8 MHz > f
CLK
> 3.5 MHz) the SI01
interface meets the I

C-bus specification for bit-rates up to 100 kbit/s.
These values are guaranteed but not 100% production tested.
