Nucleo Board vs STM32L021F4T6 mcu

[Sisto Zànier]

Hi all,
I would like to know if the use of the NUCLEO-L031K6 board is compatible with the STM32L021Fx MCU that I intend to use for a project of mine and in general if it is compatible with all the STM32L0x MCUs.

Thank you for any response.

The NUCLEO-L031K6 board uses an STM32L031K6 chip:

For the STM32L021F4, see:

For general information on the STM32L0x family, see:

https://www.st.com/en/microcontrollers-microprocessors/stm32l0-series.html 

 

There you can see that the STM32L031K6 adds a segment LCD driver - which is not available on the L02x (or any other L0 parts). <-- See @Uwe Bonnes correction!

Other features which are common should be compatible - check the datasheets for particular parts to confirm.

No, both L021 and L031 are in the access line have have no LCD. L021 has e.g. less RAM. Carefully checking the datasheets is needed/

@Uwe Bonnes - ah yes, my mistake! I've updated the post.

@Sisto Zànier - read about the 'Access Line' parts here:

https://www.st.com/en/microcontrollers-microprocessors/stm32l0x1.html 

The differences between the family members are in numbers of pins, amounts of memory, and presence/absence of the hardware encryption
