A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

I used to use stm32f4 series and moved to stm32g4 series to use the latest mcu.

But stm32g4 does not support sdio.

What is the popular mcu among stm32 series that supports sdio?

Thank you.

Hello,

What do you men by "popular mcu"? this is what important for you?

Many MCUs feature SDIO but to select a part number this is based on your needs and the application complexity/performance.

Thank you for your answer
I am choosing an MCU to study stm32 first
I meant popular, which means an MCU that is easy to obtain and has various functions
I am sorry that my question is not specific

The request still not accurate enough. "various functions" still not accurate.

As a user that needs to play with a "standard" MCU STM32F4 still a good one having SDIO.

You can move to STM32F7 series (Cortex-M7) but it needs from you to understand the complexity of CM7 vs CM4 and handle it.

STM32F746-DISCO (having SD card slot) as example to play with this serie.
