System Design Information
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
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.

Note:
1. VDD_CORE should not exceed VDD_IO, VDD_IO_MEM or PLL_AVDD by more than
2. It is recommended that VDD_CORE/PLL_AVDD should track VDD_IO/VDD_IO_MEM
3. Input voltage must not be greater than the supply voltage (VDD_IO, VDD_IO_MEM,
