NOTES:
1. Parameters are valid over operating temperature range and voltage range unless otherwise specified.
2. Load capacitance for port 0, ALE, and PSEN = 100 pF, load capacitance for all other outputs = 80 pF.
3. These values are characterized but not 100% production tested.
4. At 100 kbit/s. At other bit rates this value is inversely proportional to the bit-rate of 100 kbit/s.
5. Determined by the external bus-line capacitance and the external bus-line pull-resistor, this must be < 1
μ
s.
6. 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 = 400 pF.
