Dear STMicroelectronics Support Team,
I am currently working on a project that uses the STM32F091CBU6 microcontroller. Could you please confirm the current lifecycle status of this part and provide any available information regarding its projected End-of-Life (EOL) date or Product Change Notifications (PCNs)?
Additionally, if there is a recommended migration path or alternative part for long-term availability, kindly share those details.
Thank you for your assistance.
Best regards,
Ramanakrishnan A

Welcome @ramana_ark, to the community!
All STM32 currently in the portfolio are part of the Product Longevity Programme. This programme is a rolling commitment, whereby each family is reviewed annually to determine whether global demand justifies renewing the warranty for a further 10 years. For the STM32F091CBU6, you will find this as a small circle on its website to the right of the product name (admittedly easy to overlook). If you hover your mouse pointer over this circle, the current guaranteed time will be displayed in a pop-up. Clicking on it will take you to the website, which lists all products in the category once again.
Does it answer your question?
Regards
/Peter
