The SD Host Controller (SDHC) IP Core implements SD memory card host controller compatible with SD Physical Layer v2.0. SDHC IP core support standard SD Memory Card as well as SD High Capacity Card (SDHC). Fully register based configuration makes it very easy to integrate in wide range of application. The SLS SD Host controller IP gives full support for Altera's SOPC based system and provides communication between Altera's Avalon Bridge and Secure Digital (SD) Card.
