The Ultra Secured Digital Host Controller (uSDHC) provides the interface between the host system and the SD/SDIO/MMC cards or devices.
MITO 8M SOM provides up to two SDIO interface available for an external memory device connection.{{ImportantMessage|text= '''The availability of this interface is related to the SOM mounting option''':
* on '''NAND on board''' version, the NAND interface is internally connected, and the SD1 interface is routed externally the SOM
* on '''eMMC on board''' version, the SD1 interface is internally connected, and the NAND interface is routed externally the SOM
See Pin mapping tables for connection details.}}
