2.2.2.3 eMMC iNAND

The i.MX 6ULL processor supports eMMC versions 4.4, 4.41, and 4.5. This design uses Micron's 8-GB MTFC8GAKAJCN-4M IT, an eMMC version 5.0 memory device. The eMMC version 5.0 specification indicates is backwards compatibility, allowing it to work correctly with the processor. The data transfer speed used is HS200 mode with 1.8-V I/O voltage. The interface diagram of eMMC with the processor is shown in Figure 4.
