This section describes the DC and AC electrical characteristics for the I2C interface of the MPC8349EA.
12.1
I2C DC Electrical Characteristics
Table 42 provides the DC electrical characteristics for the I2C interface of the MPC8349EA.
12.2
I2C AC Electrical Specifications
Table 43 provides the AC timing parameters for the I2C interface of the MPC8349EA. Note that all values
refer to VIH(min) and VIL(max) levels (see Table 42).

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 MPC8349EA Integrated Host Processor Family Reference Manual, for information on the digital filter used.
4. I/O pins obstruct the SDA and SCL lines if OVDD is switched off.
