SD/eMMC Host Controller

Overview

The SD/eMMC Host Controller IP Core implements the SD Physical Layer v3.0 and eMMC Physical Layer v4.51 compatible Host Controller which supports standard SD Card, SD High Capacity Card (SDHC), SD Extended Capacity Card (SDXC) and eMMC. Fully register based configuration makes it very easy to integrate in wide range of application. The SLS SD/eMMC Host Controller IP Core gives full support for Altera's SOPC and Qsys based system and provides communication between Altera's Avalon Bridge and Secure Digital (SD) Card and eMMC.
