ANAGEMENT

The power management module obtains two power inputs.  These can be supplied from a
single 5V supply; however both pins must be powered.  Pin 5V0 drives several 3.3V low dropout
regulators for the various subsystems and must be at least 3.75V for reliability over load swings
and temperature.  The input level should not exceed 5.25V to reduce internal heat generation.
If the system will not be operated above 55⁰C then 6V (max) is acceptable.  Pin3V3 drives a
1.8V low dropout regulator for the DSP core.  The regulator can tolerate 5.35V in (6V under
55⁰C) and should exceed 2.25V for reliable operation.
