Specifications of MPC8315E-RDBA

• Lead Free Status / RoHS Status: Compliant

When switching from normal mode to D3 warm (standby) mode, first turn off the switchable I/O voltage
supply and then turn off the switchable core voltage supply. Similarly, when switching from D3 warm
(standby) mode to normal mode, first turn on the switchable core voltage supply and then turn on the
switchable I/O voltage supply.
An example of the power-up sequence is shown in
warm mode.
The switchable and continuous supplies can be combined when the D3 warm mode is not used.
The SATA power supplies VDD33PLL and VDD33ANA should go high after NVDD3_OFF supply and
go low before NVDD3_OFF supply. The NVDD3_OFF voltage levels should not drop below the
VDD33PLL, VDD33ANA voltages at any time.

When the device is in D3 warm (standby) mode, all external voltage
supplies applied to any I/O pins, with the exception of wake-up pins, must
be turned off. Applying supplied external voltage to any I/O pins, except the
wake up pins, while the device is in D3 warm standby mode may cause
permanent damage to the device.
