MPC8313E RDB Board Configuration
5.3
The MPC8313E RDB requires a power supply from the ATX power connector. The ATX supply connector
directly provides 12-V, 5-V, and 3.3-V voltages. Core voltage, DDR2 voltage, RGMII voltage, and
PHY-specific voltages are provided by either switching or linear regulated depending on the voltage drop
and current consumption requirement. MPC8313E power-down mode is supported. A regulator that can
be shut down is implemented for this purpose.
The MPC8313E does not require the core supply voltage and IO supply voltages to be applied in any
particular order. However, during the power ramp up, before the power supplies are stable, there may be
an interval when the IO pins are actively driven. After the power is stable, as long as PORESET is asserted,
most IO pins are three-stated. To minimize the time that IO pins are actively driven, apply core voltage
before IO voltage and assert PORESET before the power supplies fully ramp up.
