3.6 Power Management

The F28003x, F28P550/9 and F28P551/2/8 devices all support dual-rail (3.3 V and 1.2 V/1.25 V) or single-rail (3.3 V) with the internal LDO VREG providing the 1.2 V/1.25 V rail. This section describes the power management differences and similarities between the two devices.

A key difference with the F28P551/2/8 devices is that the core voltage nominal voltage is 1.25 V, vs the F28003x/F28P550/9 which have a 1.20 V nominal core voltage.
