The microcontrollers in the STM32F0 Series, STM32F2 Series, STM32F3 Series, STM32F4 Series, STM32F7 Series, STM32G0 Series, STM32G4 Series, STM32H7 Series, STM32L0 Series, STM32L1 Series, STM32L4 Series, STM32L4+ Series, STM32L5 Series, STM32WB Series, and STM32WL Series feature a real-time clock (RTC) peripheral designed to allow the STM32 MCUs to operate with minimum power requirements.

The applications in the X-CUBE-RTC Expansion Package aim to demonstrate how to exploit fully the RTC advantages, thus extending product battery life.
