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.

Reference voltage circuits in microcontroller systems

A microcontroller system is determining to exit a power saving mode and, in response, enable a reference current source to begin providing a reference current for a memory module. The microcontroller system determines that the reference current has reached a substantial fraction of a target reference current, and, in response to determining that the reference current has reached a substantial fraction of the target reference current, enables the memory module to begin performing one or more memory operations.
