Overview
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.
- 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

- Reducing Active Mode Power Consumption In active mode, the core is fetching instructions from memory and executing those instructions, and a large number of peripherals may be active at once. This section discusses ways to reduce the SiM3L1xx device power consumption in active mode (Normal, PM1, PM4, or PM5).
