Abstract

A microcontroller system includes a higher power reference voltage circuit and a lower power reference voltage circuit configured to draw less power than the higher power reference voltage circuit when enabled. The system includes a power state logic controller configured to enable the lower power reference voltage circuit to provide a first regulated voltage during a power saving mode, and, on exiting the power saving mode, enable the higher power reference voltage circuit to provide a second regulated voltage.
