I want to use STM32G series for SDIO, so that I can use eMMC card. we can not use other stm32 controller.

[NANWA.1]

Dear Sir,

we are using STM32G series controller in our project but the problem is that we are also using eMMC card with 4GB which work on SDIO connectivity.

could you plese share me which STM32g series will be suitable for it.

Thank you

Neither the STM32G0 nor the STM32G4 families support SDMMC operation. However, you could use the card in SPI mode at reduced bandwidth. Both families can do SPI.
