Output Driver Characteristics
Table 3 provides information on the characteristics of the output driver strengths. The values are
preliminary estimates.
2.2
Power Sequencing
The MPC8572E requires its power rails to be applied in a specific sequence in order to ensure proper
device operation. These requirements are as follows for power up:
1. VDD, AVDD_n, BVDD, LVDD, OVDD, SVDD_SRDS1 and SVDD_SRDS2, TVDD, XVDD_SRDS1 and
XVDD_SRDS2
2. GVDD
All supplies must be at their stable values within 50 ms.
Items on the same line have no ordering requirement with respect to one another. Items on separate lines
must be ordered sequentially such that voltage rails on a previous step must reach 90% of their value before
the voltage rails on the current step reach 10% of theirs.
In order to guarantee MCKE low during power-up, the above sequencing for GVDD is required. If there is
no concern about any of the DDR signals being in an indeterminate state during power-up, then the
sequencing for GVDD is not required.

Notes:
1. The drive strength of the local bus interface is determined by the configuration of the appropriate bits in PORIMPSCR.
2. The drive strength of the DDR2 or DDR3 interface in half-strength mode is at Tj = 105°C and at GVDD (min).
