This application note aims at describing the key low power features of the STM32L15x family and explains their benefits for applications where energy consumption is a major concern.
The document provides an overview of the STM32L15x product line from STMicroelectronics, which belongs to the EnergyLite platform. It highlights how these 32-bit Cortex-M3 based microcontrollers offer extended memory and larger packages while maintaining pin-to-pin compatibility with the STM8L family.
The internal low drop regulator supplies most of the logic circuitry with a fixed voltage down to 1.65 V.
The device can execute code at a maximum frequency of 32 MHz in high-performance mode.
The 12-bit / 1 MSps ADC has a typical consumption of 1.45 mA if left powered-up continuously.
