Power Up/Down Sequencing
Figure 51 shows situations in sequencing the I/O VDD (VDD_IO), Memory VDD (VDD_IO_MEM), PLL VDD
(PLL_AVDD), and Core VDD (VDD_CORE).

1 All “open drain” outputs of the MPC5200B are actually regular three-state output drivers with the output data tied low
and the output enable controlled. Thus, unlike a true open drain, there is a current path from the external system to
the MPC5200B I/O power rail if the external signal is driven above the MPC5200B I/O power rail voltage.

Note: VDD_CORE should not exceed VDD_IO, VDD_IO_MEM or PLL_AVDD by more than 0.4 V at any time, including
power-up.
Note: It is recommended that VDD_CORE/PLL_AVDD should track VDD_IO/VDD_IO_MEM up to 0.9 V then separate
for completion of ramps.
Note: Input voltage must not be greater than the supply voltage (VDD_IO) VDD_IO_MEM, VDD_CORE, or PLL_AVDD)
by more than 0.5 V at any time, including during power-up.
Note: Use 1 microsecond or slower rise time for all supplies.
