AN725 A D VA N C E D L OW P OWER TECHNIQUES FOR SiM3L1 XX D EVICES 1. 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. Active Mode Low Power Mode Figure 1. Defining the Power Budget—Active and Low Power Modes 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. www.DataSheet.net/ 2. Key Points This key topics of this document are as follows: How to reduce active mode time and power consumption to reduce low power mode power consumption Measuring the low power modes on an SiM3L1xx MCU card General power-saving tips How 3.
