Question

Where can I find a Parametric Search for STM32 products?

Hi all,

I am looking for a low power STM32 device with 4 usable UARTS (either UART, USART, or LPUART).

How do I search the st.com site?

I have managed to filter down to 324 devices - do I have to individually download and read ALL 324 datasheets to filter further?

Kind regards

PG

    Hello @PGump.1 

    You can use the ST-MCU-FINDER which is an easy-to-use selection tools, self-maintaining documentation, and connections to MCU communities.

    Also, you can use the STM32CubeMX which will do the same job.

    Thank you for your reply @STTwo-32 . I was hoping that the ST website could do it. I use Linux, and unfortunately many of the ST tools are problematic...

    The MX tool embedded in Cube often crashes my project - I just use it for the bare-minimum of settings.

    I have tried the standalone MX, but many of the sliders in the selector panels don't work! And I can't expand the fields in the panels either!

    I have just installed ST-MCU-FINDER, it's better than MX, but it doesn't work correctly - I set the minimum UARTS to 4, it list the STM32L151 as an options, but it only has 3 UARTS! It doesn't see that Cube is installed, and I can't expand the part number field enough to get the full part number to transfer manually.

    Even doing it manually with the datasheets is problematic - The STM32L432 states it has 4 UARTS, but MX only lists 3, and 2 UARTS share the same pins!!!

    Sorry to be a pain, but I don't understand why this is so difficult.

    Kind regards

    Update: After running MX or FINDER, my CubeIDE is broken! The main screen opens, but I cannot open project files - it states that there is "No Consoles" available for the files.

    I had to download and reinstall CubeIDE, and import the projects into it...

    Kind regards

    The basic selector/table is at https://www.st.com/en/microcontrollers-microprocessors/stm32-high-performance-mcus/products.html , https://www.st.com/en/microcontrollers-microprocessors/stm32-mainstream-mcus/products.html, https://www.st.com/en/microcontrollers-microprocessors/stm32-ultra-low-power-mcus/products.html - this is purely web-based, although somewhat cumbersome.

    As a Linux user you may be inclined to process the raw data from which the both CubeMX and the finder work, which are xml files of quite clear structure, at https://github.com/STMicroelectronics/STM32_open_pin_data/tree/master/mcu

    Thank you for your reply @waclawek.jan.

    But I'm looking for a solution, not another project...! Unless ST are paying?

    Kind regards

    Hi all,

    It looks like ST DO NOT offer a solution to this problem...

    Kind regards
