Symbol Parameter Condition Min. Max Units
t
BUF
Bus free time between a STOP
and START condition
f
SCL
≤ 100 kHz 4.7 – μs
f
SCL
> 100 kHz 1.3 – μs
Note:
1. This parameter is characterized and not 100% tested.
2. Required only for f
SCL
> 100 kHz.
3. C
b
= capacitance of one bus line in pF.
4. f
CK
= CPU clock frequency.
5. This requirement applies to all two-wire serial interface operation. Other devices connected to the
two-wire serial bus need only obey the general f
SCL
requirement.
