Figure 12. Supply Voltage Sequencing and Separation Cautions
The relationship between SDV
DD
and EV
DD
is non-critical during power-up and power-down sequences.
Both SDV
DD
(2.5V or 3.3V) and EV
DD
are specified relative to IV
DD
.
5.4.2.1
If EV
DD
/SDV
DD
are powered up with IV
DD
at 0 V, then the sense circuits in the I/O pads will cause all
pad output drivers connected to the EV
DD
/SDV
DD
to be in a high impedance state. There is no limit on
how long after EV
DD
/SDV
DD
powers up before IV
DD
must powered up. IV
DD
should not lead the EV
DD
,
SDV
DD
or PLLV
DD
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
μ
s to avoid turning
on the internal ESD protection clamp diodes.
Power Up Sequence
The recommended power up sequence is as follows:
1. Use 1
μ
s or slower rise time for all supplies.
2. IV
DD
/PLLV
DD
and EV
DD
/SDV
DD
should track up to 0.9 V, then separate for the completion of
ramps with EV
DD
/SD V
DD
going to the higher external voltages. One way to accomplish this is to
use a low drop-out voltage regulator.
5.4.2.2
If IV
DD
/PLLV
DD
are powered down first, then sense circuits in the I/O pads will cause all output drivers
to be in a high impedance state. There is no limit on how long after IV
DD
and PLLV
DD
power down before
EV
DD
or SDV
DD
must power down. IV
DD
should not lag EV
DD
, SDV
DD

DD
going low by more

Notes:
1.
IV

should not exceed EV

0.4 V at any time, including power-up.
Recommended that IV

DD
should track EV

up to
0.9 V, then separate for completion of ramps.
Input voltage must not be greater than the supply voltage (EV

IV

DD
) by more than 0.5 V at any time, including during power-up.
Use 1
