Part Number: AM3357


Hi,

I am interfacing Sitara processor with a eMMC chip. Do I need to supply the eMMC chip with 3V3 or 1V8. Here is my schematics.

    You should power the eMMC device based on the requirements defined in its datasheet. You should ask the eMMC manufacture any questions specific to the eMMC device operation. The AM335x IO power rail associated with the pins connected to the eMMC device should be powered by the same source that is used to power the eMMC IO connected to AM335x. AM335x IOs supports 1.8V or 3.3V operation. I would recommend using 1.8V if that is an option for the eMMC device.

    Regards,
