I2C AC Electrical Specifications
Table 40 provides the AC timing parameters for the I2C interface of the MPC8541E.
Capacitance for each I/O pin

pF
Notes:
1. Output voltage (open drain or open collector) condition = 3 mA sink current.
2. CB = capacitance of one bus line in pF.
3. Refer to the MPC8555E PowerQUICC III Integrated Communications Processor Reference Manual for information on the
digital filter used.
4. I/O pins will obstruct the SDA and SCL lines if OVDD is switched off.
