The SD Slave Controller IP cores provide the simplest way to design a Secure Digital (SD) or MultiMedia Card (MMC) device. It serves as a bridge between the SD bus and user's application logic inside the card. It contains many flexible design features that allows it to be easily integrated to any card applications. It supports SD memory, SDIO, SDHC, MMC and combo card functions.

The SD slave controllers process all the bus request from the SD bus locally. It contains the standard card register set and state machines so that most request from the host are handled automatically without support from the user logic. This frees the application logic from the SD protocol constraints. Only data access are forwarded to user's application logic as read/write request.

The SD slave controller IP core can be configured to operate as a DMA engine to access user logic or as a slave with interrupt. In DMA mode, the core is a bus master and requires minimum service from user logic. In interrupt mode, the IP core request service fro the user's local micro-controller through interrupt request. This allows the user logic to have maximum control of the device operation.
