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 monthly 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 monthly 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.

Table 11. Pin assignment and description

Current:

The footnote (1):

1.    PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 in output mode is limited:

- The speed should not exceed 2 MHz with a maximum load of 30 pF

- These GPIOs must not be used as current sources (for example to drive a LED).

Expected:

Update the footnote (1):

1. PC13, PC14 and PC15 are supplied through the power switch. Since the switch only provides a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 in output mode is limited:

- The speed should not exceed 2 MHz with a maximum load of 30 pF

- These GPIOs can be used as current sinks but not as current sources.

Jun 2024

Expected:

Add this note and mark the pins mentioned here with a note marker stating this:

- Upon reset, a pull-down resistor might be present on PA8, PB15, PD0, or PD2 depending on voltage level on PA9, PA10, PD1, and PD3, respectively. In order to disable this resistor, strobe the UCPDx_STROBE bits in SYSCFG_CFGR1 register during start-up sequence.
