iWave Systems' controller IP core supports secure digital, a multimedia cards, SD combo cards, SDHC UHS-I, and SDXC

Image of iWave Systems' SD/SDIO Host Controller 3.0 (click to enlarge)iWave Systems' SD/SDIO 3.0 host controller is compatible with the SD physical layer (PHY) Specification Version 3.0. The core supports the AXI4 lite interface for control and status register access and the AXI4 memory-mapped (AXI4-MM) interface for data transfer through the ADMA2 mode. The host interface is compatible with the standard register set for the host controller as per the SD host controller Specification Version 3.0.

    • Programmable clock frequency generation to the SD card
    • Interrupt and ADMA2 transfer mode of operation
    • Timeout monitoring for response, data, CRC token, and busy
    • Block length: 2 Kb (max.)
    • Single-block and multi-block data transfer
    • 32-bit AXI4-MM interface towards the host processor
    • 32-bit AXI4-Lite interface towards the SD host controller
    • Default-speed and high-speed including SDR12, SDR25, DDR50, SDR50, and SDR104 modes
  • Individual 2 Kb data buffer for read and write
  • Cyclic redundancy check (CRC) for command and data
  • Controller supports standard register set for the host controller
  • Core offers UHS-I mode of operation
