System Design Information
These requirements are shown graphically in Figure 16.
Figure 16. MPC7448 Power Up Sequencing Requirements
Certain stipulations also apply to the manner in which the power rails of the MPC7448 power down, as
follows:
OVDD may ramp down any time before or after VDD.
The voltage at the SYSCLK input must not exceed VDD once VDD has ramped down below 0.9 V.
The voltage at the SYSCLK input must not exceed OVDD by more 20% during transients (see
overshoot/undershoot specifications in Figure 2) or 0.3 V DC (see Table 2) at any time.
