TMS570LC4357: power supply

I am using the TI hercules to build a safety critical system. Does the system require an additional MCU for power supply?
(apologies if this is a dumb question)

    Hello kakashi,

    The Hercules device family products require an external device to supply the necessary voltages and currents for proper operation. Separate voltage rails are available for core logic (1.2V) and I/O logic (3.3V, including MibADC).

    Management of voltage supervision at system level can be simplified by using a TI TPS6538x power supply.

    Hercules device doesn't require another MCU to provide powers.
