Electrical Characteristics
2.2
Power-Up/Down Sequence
The MPC8640 requires its power rails to be applied in a specific sequence to ensure proper device
operation.
NOTE
The recommended maximum ramp up time for power supplies is 20
milliseconds.
The chronological order of power up is:
1. All power rails other than DDR I/O (Dn_GVDD, and Dn_MVREF).
NOTE
There is no required order sequence between the individual rails for this
item (# 1). However, VDD_PLAT, AVDD_PLAT rails must reach 90% of
their recommended value before the rail for Dn_GVDD, and Dn_MVREF (in
next step) reaches 10% of their recommended value. AVDD type supplies
must be delayed with respect to their source supplies by the RC time
constant of the PLL filter circuit described in Section 20.2.1, “PLL Power
2. Dn_GVDD, Dn_MVREF
NOTE
It is possible to leave the related power supply (Dn_GVDD, Dn_MVREF)
turned off at reset for a DDR port that will not be used. Note that these power
supplies can only be powered up again at reset for functionality to occur on
the DDR port.
3. 3. SYSCLK
The recommended order of power down is as follows:
1. Dn_GVDD, Dn_MVREF
2. All power rails other than DDR I/O (Dn_GVDD, Dn_MVREF).
NOTE
SYSCLK may be powered down simultaneous to either of item # 1 or # 2 in
the power down sequence. Beyond this, the power supplies may power
down simultaneously if the preservation of DDRn memory is not a concern.
See Figure 3 for more details on the power and reset sequencing details.
