Power-on S equenc e
Three power-on sequences are given below Sequence #1 is recommended because it will prevent I/O conflicts and will also allow the input signals
to propagate when the I/O powers are brought up.
Note:
The ESD diodes may be damaged if one of the voltages is applied and one of the other voltages is at a ground level.
A
. Recommended Sequence
t2 > 0 whenever possible (V

Core)
t1 - t2 can be 0 (V

B
. Reverse Voltage Sequence
If sequence A is not feasible, then Sequence B can be used:
t1 <50ms and t2 <50ms to prevent damage.
C
. Simultaneous Power-up
VccI/O, VccSI/O, and VccCore can be powered up simultaneously.
