How to select STM32 according to project needs [Copy link]

How do you choose the key parameters of the chip based on the project, such as main frequency, flash, etc.

Give an example and then we can discuss the selection.

Choose the core and use the highest configuration single-piece chicken in this series to make a prototype, then reduce the configuration and finally finalize it.

It depends on the specific situation of the system. What peripherals are there, what are the corresponding interfaces, what are the interface parameter requirements, what level of chip is needed, main frequency, storage, etc., and leave some margin.

This question is too complicated to explain, and it needs to be comprehensively considered. Fortunately, the pin arrangements of various stm32 models are compatible, with only a little difference, which is really good. If the qfp100 package f1 is not good, then f4 is used, and if it is not enough, then f7 is used. However, there are many reasons for re-modifying the board, not just the MCU. It is rare that one board is successful.
