• Description: Mpc8560 Powerquicc Iii Integrated Communications Processor
• Manufacturer: Freescale Semiconductor, Inc

2.1.2 Power Sequencing
The MPC8560 requires its power rails to be applied in a specific sequence in order to ensure proper device
operation. These requirements are as follows for power up:
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 percent of their value
before the voltage rails on the current step reach 10 percent of theirs.
