STM32 MCU datasheets: Expected preliminary updates

Imen.D
ST Employee

Introduction 

This article includes preliminary updates of STM32 MCU datasheets reported since 1st January 2024.  It highlights the current description requiring update and the expected one if available.

The purpose of this article is to deliver any expected updates to our MCU datasheets prior to actual documentation releases. We wish to be transparent with our updates and provide them as fast as possible, to assist you in your design process.
This article is updated on a quarterly basis. Once these preliminary updates are manifested in the datasheets, this article is refreshed with new information.
Moving forward, we are also working on providing datasheet releases on a more frequent basis.

IMPORTANT NOTICE - READ CAREFULLY :

  • STMicroelectronics NV and its subsidiaries (“ST”) reserve the right to make changes, corrections, enhancements, modifications, and improvements to this article at any time without notice.
  • Information in this article supersedes and replaces information previously supplied in any prior versions of this article.
  • The following table gives a quick reference to the preliminary documentation updates which may be changed or improved without notice. 
  • This article will be reviewed on a quarterly basis and applied updates will be removed from the table.
  • The hyperlinks under "Doc Reference - Revision" provides a direct link to the specific document page where the description is located.
