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.
