Introduction
The system power budget of a low power system has two components: active and low power mode. Active mode periods include an active core executing code or a larger number of active peripherals. In low power mode periods, the core enters a sleep state and fewer peripherals are active.

SiM3L1xx devices have several features to address reducing power consumption in all operational modes to achieve a longer product lifetime in battery-operated systems. This document addresses each of these features and provides guidelines for achieving low power consumption in a variety of configurations and applications.
