VCCPLL Pin Requirements
If the voltage on the VCCPLL power supply pin exceeds the V
CC
pin voltage by 0.5 V at any time,
including the power up and power down sequences, excessive currents can permanently damage
on-chip electrostatic discharge (ESD) protection diodes. The damage can accumulate over
multiple episodes.
Pragmatically, this problem only occurs when the VCCPLL and V
CC
pins are driven by separate
power supplies or voltage regulators. Applications that use one power supply for VCCPLL and
V
CC
are not typically at risk. Verify that your application does not allow the VCCPLL voltage to
exceed V
CC
by 0.5 V.
The VCCPL low-pass filter recommended in the Developer’s Manual does not promote this
problem.
