==Peripheral SDIOs ==

The Ultra Secured Digital Host Controller (uSDHC) provides the interface between the host system and the SD/SDIO/MMC cards or devices.

MITO 8M Mini/Nano SOM provides up to two SDIO interface available for an external memory device connection.

'''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.
=== Description ===

The SDIOs interface available on MITO 8M Mini/Nano is based on iMX8M Mini/Nano SoC.

The SDIOs port supports the following standards and features:

*Conforms to the SD Host Controller Standard Specification version 2.0/3.0
*Compatible with the MMC System Specification version 4.2/4.3/4.4/4.41/5.0/5.1
*Compatible with the SD Memory Card Specification version 3.0 and supports the Extended Capacity SD Memory Card
*Compatible with the SDIO Card Specification version 2.0/3.0
*Supports 1-bit/4-bit SD and SDIO modes, and 1-bit/4-bit/8-bit MMC modes
*Card bus clock frequency up to 208 MHz

===Pin mapping===

The Pin mapping is described in the [[MITO 8M Mini SOM/MITO 8M Mini Hardware/Pinout_Table | Pinout table section]]
