SDIO-HOST - SD/SDIO/MMC/eMMC Card Host Controller

alt

The SDIO-HOST is an SD/SDIO/MMC/eMMC host controller compatible with the SD Host Specification version 3.0. It supports SD Physical Layer 3.01, SDIO 3.0, and MMC/eMMC 4.41 specifications.

The configurable multi-slot architecture makes the design suitable for a wide range of applications, including very low area designs. Each slot can be individually controlled through the Standard Register Set
