The JEDEC standard for eMMC 4.4 introduces the dual data rate. Does the NXP part support this dual data rate? I don't see any mention of it although the user manual says the SD/MMC interface supports MMC version 4.4. Thanks.

Hi, toad,

We have not validated the dual data rate function. The understanding is the protocol is probably supported - however, the eMMC 4.4 dual data rate is specified at 1.8V which this part does not support.

Thanks!
