EP550 SD/SDIO/MMC Host Controller

Features

• Host controller for SDIO, SD memory card, and MMC interface.
• Allows host CPU to access SD and MMC devices.
• Simple user interface optimized for on-chip bus connection.
• User interface supports 32-bit and 64-bit data.
• Option to integrate with other CPU bus slaves to support direct access by various CPU's including PowerPC, MPC860, ARM, SH2/3/4, MIPS, and ARC microprocessors.
• Supports SDIO DMA operation for high speed data transfer.
• Implement SD host controller standard register set for support of standard SDIO development tool.
• Supports SDIOworx™ embedded SDIP stack/bus driver
• Fully programmable access timing.
• Hardware support of CRC error detection and interrupt generation
• Supports multi-function SD cards, command suspend, resume, and block transfers.
• Option to operate the user interface and card interface at different clock domains.
• Direct mapping of host address space to card address space.
• Designed for ASIC and FPGA implementations.
• Fully static design with edge triggered flip-flops.
