ADVANCED LOW POWER TECHNIQUES FOR SiM3L1XX

DEVICES

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

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.

2. Key Points

This key topics of this document are as follows:

How to reduce active mode time and power consumption

How to reduce low power mode power consumption

Measuring the low power modes on an SiM3L1xx MCU card

General power-saving tips

3. Relevant Documentation

Precision32™ Application Notes are listed on the following website: www.silabs.com/32bit-appnotes.

AN666: Usage Guide for e SiM3U1xx,SiM3C1xx, and SiM3L1xx DMA and DTM Modules

AN720: Precision32™ Optimization Considerations for Code Size and Speed

AN667: Getting Started with the Silicon Labs Precision32 IDE

AN670: Getting Started with the Silicon Labs Precision32 AppBuilder
