Where to fine STM32 product selector based on certain selection criteria?

[Amelie ACKERMANN]

Where can I find a STM32 product selector - that allows us to enter power, I/O types, and other required features - and be presented with suitable STM32 processors?

Hello, I recommend to download free tool STM32CubeMX which embeds active product selector, where you can filter by many parameters the best fitting STM32 to your application.
