NOTES:
1. At 100 kbit/s. At other bit rates this value is inversely proportional to the bit-rate of 100 kbit/s.
2. Determined by the external bus-line capacitance and the external bus-line pull-resistor, this must be < 1
μ
s.
3. Spikes on the SDA and SCL lines with a duration of less than 3 t
CLCL
will be filtered out. Maximum capacitance on bus-lines SDA and
SCL = 400pF.
4. t
CLCL
= 1/f
OSC
= one oscillator clock period at pin XTAL1. For 62ns (42s) < t
CLCL
< 285ns (16MHz (24Hz) > f
OSC
> 3.5MHz) the SI01
interface meets the I
2
C-bus specification for bit-rates up to 100 kbit/s.
5. These values are guaranteed but not 100% production tested.
