Figure 51. Supply Voltage Sequencing
The relationship between VDD_IO_MEM and VDD_IO is non-critical during power-up and power-down
sequences. Both VDD_IO_MEM (2.5 V or 3.3 V) and VDD_IO are specified relative to VDD_CORE.
5.1.1
Power Up Sequence
If VDD_IO/VDD_IO_MEM are powered up with the VDD_CORE at 0V, the sense circuits in the I/O pads
will cause all pad output drivers connected to the VDD_IO/VDD_IO_MEM to be in a high-impedance
state. There is no limit to how long after VDD_IO/VDD_IO_MEM powers up before VDD_CORE must
power up. VDD_CORE should not lead the VDD_IO, VDD_IO_MEM or PLL_AVDD by more than 0.4
V during power ramp up or there will be high current in the internal ESD protection diodes. The rise times
on the power supplies should be slower than 1 microsecond to avoid turning on the internal ESD protection
clamp diodes.
The recommended power up sequence is as follows:
Use one microsecond or slower rise time for all supplies.
VDD_CORE/PLL_AVDD and VDD_IO/VDD_IO_MEM should track up to 0.9 V and then separate for
the completion of ramps with VDD_IO/VDD_IO_MEM going to the higher external voltages. One way
to accomplish this is to use a low drop-out voltage regulator.

Note:
1. VDD_CORE should not exceed VDD_IO, VDD_IO_MEM or PLL_AVDD by more
than 0.4 V at any time, including power-up.
2. It is recommended that VDD_CORE/PLL_AVDD should track
VDD_IO/VDD_IO_MEM up to 0.9 V then separate for completion of ramps.
3. Input voltage must not be greater than the supply voltage (VDD_IO)
VDD_IO_MEM, VDD_CORE, or PLL_AVDD) by more than 0.5 V at any time,
