Does STM32F7 and H7 support eMMC of 8GB?

JProb.1 · ‎2021-02-15

Hello,

I would like to use an eMMC of 8GB with one of these three MCUs: STM32F411VET6, STM32F765VIT6 and STM32H7A3VIT6.

Do these MCU support eMMC of 8GB and does ST provides working drivers for this(as this project must go fast)?

Many thanks,

I've had eMMC working on all those platforms, it works via SDIO/SDMMC interface, up to 8-bit wide as supported by the HW/pins, and capacities as presented by the memory chip. Functionality of 4GB thru 256GB would be materially identical.

Not all these would be able to clock the interface at 52 MHz

SanDisk parts ran reasonably fast with FatFs
