Peripheral SDIOs[edit | edit source]
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[edit | edit source]
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
