产品概述
描述
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.
For more details, refer to the Using the hardware real-time clock (RTC) and the tamper management unit (TAMP) with STM32 microcontrollers application note (AN4759), available on www.st.com.

Follow issues and share solutions on Github for STM32Cube MCU packages. Integrate your own software components in a STM32Cube Expansion for STM32CubeMX and STM32CubeIDE tools, thanks to the new STM32PackCreator utility
STM32CubeMX is part of the STM32Cube initiative designed to simplify and accelerate the development of applications for STM32 microcontrollers. STM32CubeMX offers the possibility to generate C projects using embedded software offers packages like CMSIS-Pack compliant software packs. Starting with the 6.0.0 revision, STM32CubeMX is delivered with STM32PackCreator, an STM32 pack creation graphical companion tool, whose main purpose is the creation of software packs.
The STM32Cube.AI is an extension pack of the widely used STM32CubeMX configuration and code generation tool enabling AI on STM32 Arm® Cortex®-M-based microcontrollers.
