Wiky Liao

Part Number: MSPM33C3219

Hi Expert,

Could you help to confirm if our M33C3219 support SDIO interface? We need to communicate the SD card in application. I don't find related wording in M33C3219 datasheet, need your kindly confirm, thanks.

SDIO means standard IO.

M33 support SDIO, HSIO and HDIO.

Hi Yuhao,

Our application requires SD card communication, SDIO or SDMMC interface is required. It is not meaning standard IO. You can refer to below topic in STM32L431 datasheet.

Update SDMMC description in L431 D/S.

No M33C32 does not have interface similar to SDMMC. For external memory, M33C32 has QSPI for external NOR flash.
