The F28002x and F280013x devices have similar options for power, with F280015x and F280013x-64VPM having an additional power option. F28002x and F280013x devices only support single-rail (3.3 V) with the internal LDO VREG providing the 1.2 V rail. F280015x and F280013x-64VPM have an additional option to supply the 1.2V rail externally, but can still be supplied internally as in the other two devices. This section describes the power management differences and similarities between the three devices.
