Power System and Reset Behavior

Operation of the phyCORE-TC1796 requires only one supply voltage.

Supply voltage: +3.3 V ± 5 % ( max.: 1200mA ; typ.: 400mA )

Once all voltages have reached their target level the voltage
supervisory circuit keeps the /PORST reset signal at low level (low is
the active level) for additional 200 ms. Then the /PORST signal
switches to high level (inactive) and the controller's boot sequence
starts.
