4.3.1
The power-up sequence should be completed as follows:
Freescale Semiconductor
1. Assert Power on Reset (POR).
2. Turn on digital logic domain and IO power supply: VDDn, NVCCx
3. Wait until VDDn and NVCCx power supplies are stable + 32 μs.
4. Turn on all other power supplies: PHY1_VDDA, USBPHY1_VDDA_BIAS, PHY2_VDD,
5. Wait until PHY1_VDDA, USBPHY1_VDDA_BIAS, PHY2_VDD, USBPHY1_UPLLVDD,
6. Deassert the POR signal.
USBPHY1_UPLLVDD, OSC24M_VDD, OSC_AUDIO_VDD, MVDD, PVDD, FUSEVDD.
(Always FUSE_VDD should be connected to ground, except when eFuses are to be
programmed.)
OSC24M_VDD, OSC_AUDIO_VDD, MVDD, PVDD, (FUSEVDD, optional). Power supplies
are stable + 100 μs.
Powering Up
Deviation from these sequences may also result in one or more of the
following:
•
•
•
Excessive current during power-up phase
Prevent the device from booting
Programming of unprogrammed fuses
