Freescale Semiconductor
Power Characteristics
NOTE
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.

Power Characteristics
The power dissipation of VDD for various core complex bus (CCB) versus the core and QE frequency for
MPC8568E is shown in Table 5. Note that this is based on the design estimate only. More accurate power
number will be available after we have done the measurement on the silicon.

Notes:
1. CCB Frequency is the SoC platform frequency which corresponds to DDR data rate.
2. Typical 65
°C based on VDD=1.1V, Tj=65.
3. Typical 105
°C based on VDD=1.1V, Tj=105.
4. Maximum based on VDD=1.1V, Tj=105.
