STM32 interface with eMMC

[kuroo]

Hi,

We are currently developing board using the STM32F765 microcontroller and eMMC memory (part numbers: MX52LM08A11XVI and IS21ES08GA-JCLI) via the SDMMC interface in STM32Cube.

Can you help us determine if the MX52LM08A11XVI and IS21ES08GA-JCLI can interface with the STM32F765 using the SDMMC peripheral?

Thank you

Hello @kuroo and welcome to the community;

According to the reference manual,  the version of the SDMMC supports in STM32F765 only one SD/SDIO/MMC4.2 card at any one time and a stack of MMC4.1 or previous.

Thank you.

Hi Kaouthar,

We only use one eMMC IC: either the MX52LM08A11XVI or the IS21ES08GA-JCLI. Could you please help me check if these two eMMCs are compatible with the STM32F765?

Thank you

Hello @kuroo ;

To check if the memory is supported by the SDMMC you need to verify that the memory is supported by the MultiMediaCard System Specification Standard.

For example according the STM32F765 reference manual; the SDMMC in this STM32 complies with MultiMediaCard System Specification Version 4.2.

Thank you.
