2.2
Power Sequencing
The MPC8610 requires its power rails to be applied in a specific sequence in order to ensure proper device operation. These
requirements are as follows:
The chronological order of power up is:
1.
OVDD, BVDD
2.
VDD_PLAT, AVDD_PLAT, VDD_Core, AVDD_Core, AVDD_PCI, SnVDD, XnVDD, SDnAVDD (this rail must reach
90% of its value before the rail for GVDD and MVREF reaches 10% of its value)
3.
GVDD, MVREF
4.
SYSCLK
The order of power down is as follows:
1.
SYSCLK
2.
GVDD, MVREF
3.
VDD_PLAT, AVDD_PLAT, VDD_Core, AVDD_Core, AVDD_PCI, SnVDD, XnVDD, SDnAVDD
4.
ODD, BVDD
NOTE
AVDD type supplies should be delayed with respect to their source supplies by the RC time
constant of the PLL filter circuit described in Section 3.2, “Power Supply Design and
Local bus

35
BVDD = 3.3 V
BVDD = 2.5 V

BVDD = 3.3 V
BVDD = 2.5 V
BVDD = 1.8 V
PCI, DUART, DMA, interrupts, system control and clocking, debug,
test, JTAG, power management, and miscellaneous I/O voltage

Notes:
1. See the DDR control driver registers in the
MPC8610 Integrated Host Processor Reference Manual, for more information.
2. See the POR impedance control register in the
MPC8610 Integrated Host Processor Reference Manual, for more information
about local bus signals and their drive strength programmability.
3. See Section 1, “Pin Assignments and Reset States,” for details on resistor requirements for the calibration of
SD
n_IMP_CAL_TX and SDn_IMP_CAL_RX transmit and receive signals.
4. Stub series terminated logic (SSTL-25) type pins.
5. Stub series terminated logic (SSTL-18) type pins.
6. The drive strength of the DDR interface in half strength mode is at Tj = 105°C and at GVDD (min).
