Power Supply Voltage Specification
Table 2 provides the recommended operating conditions for the MPC8323E. Note that these values are the
recommended and tested operating conditions. Proper device operation outside of these conditions is not
guaranteed.
Figure 2 shows the undershoot and overshoot voltages at the interfaces of the MPC8323E

Note:
1. GVDD, OVDD, AVDD, and VDD must track each other and must vary in the same direction—either in the positive or negative
direction.
2. Minimum temperature is specified with TA; maximum temperature is specified with TJ.
3. All IO pins should be interfaced with peripherals operating at same voltage level.
4. This voltage is the input to the filter discussed in Section 24.2, “PLL Power Supply Filtering” and not necessarily the voltage
at the AVDD pin, which may be reduced due to voltage drop across the filter.
