There is not a significant difference in power consumption between F280013x, F280015x and F28002x if a similar system operating frequency is chosen, the same number of peripherals are being utilized, and internal VREG is being used for all three devices. However, since the F280015x and F280013x (F280013x-64VPM package only) devices have the option to supply VREG externally, they have the capability to be more power efficient.
One additional consideration is that F280015x and F280013x have a maximum frequency of 120 MHz. This increases the power requirements when compared to F28002x, whose maximum frequency is 100 MHz.
