The SD host controller provides the capability to the system host CPU to communicate with external SD cards. It supports SD memory, SDSC, SDHC, SDIO, SD Combo and MultiMedia Cards (MMC).
The SD host controller core is compliant to the latest SD host specification, verion 2.0. The core is a standard register set to the OS and application software. To access the SD card, the host CPU simply access the control registers inside the core and the core handles all the SD card protocol automatically including data shifting, timing and CRC generation. The core has built-in DMA controller so that data can be automatically transferred between system memory and the SD card without CPU intervention. Because it supports the standard SD register set, the SD host controller is recognized by any operating systems that supports the SD bus. No driver development is needed. In applications where the operating system does not have built-in SD support, Eureka provides free source code to user for bus driver development.
With this IP core, SD card interface can be realized with very little development cost and effort. Designer can add SD memory and SDIO interface to any system by simply adding the SD host controller core without impacting system architecture.
