This is an application note about power management of STM8L family products, which introduces power management modes and how to use these products in these modes.
This document is intended for application designers requiring a hardware implementation overview of low power modes in the STM8L product families. It explains differences between various modes and offers examples on selecting the best mode for specific application needs.
The note covers power consumption factors, internal supply structures for different device series (STM8L101xx and STM8L15x), clock management systems, and detailed descriptions of run and low power modes including Wait, Low Power Run, Halt, and Active-halt modes.
| Supply voltage range (STM8L101xx) | 1.65 V up to 3.6 V |
|---|---|
| Supply voltage range (STM8L15x) | 1.8 V to 3.6 V |
| Low power regulator current capability | 200 uA |
| Main voltage regulator current capability | up to 25 mA |
No, the BOR is available on STM8L15x devices only.
Yes, each peripheral clock can be switched on or off independently using the PCG feature.
