Electrical Characteristics

This figure shows the undershoot and overshoot voltages at the interfaces of the MPC8314E.

Output Driver Characteristics

This table provides information on the characteristics of the output driver strengths. The values are

preliminary estimates.

Note:

1. The NVDDx_ON are static power supplies and can be connected together.

2. The NVDDx_OFF are switchable power supplies and can be connected together.

3. Minimum Temperature is specified with TA;maximum temperature is specified with TJ.

4. All Power rails must be connected and power applied to the MPC8314 even if the IP interfaces are not used.

5. All I/O pins should be interfaced with peripherals operating at same voltage level.

6. This voltage is the input to the filter discussed in Section 25.2, “PLL Power Supply Filtering” and not necessarily the voltage

at the AVDD pin.

7. All 1V power supplies should be derived from the same source.
