The Expert of IP Core & Embedded

SDXC card IPcore compliant with SD Specifications Version 3.01 and support both High-speed SD card (Class6), SDHC card and SDXC card. It supports SDR50 mode and achieves High-speed transmission up to 50MB/s (support SDR104 mode soon). DesignGateway provide demo bit file for AMD ML505/506 for evaluation. You can easily evaluate SDXC card IP core on the board before purchasing.

Features

• Compliant with SD Specifications Part 1 Physical Layer version 3.01
• Support both SD/SDHC/SDXC card
• Auto detect SD card type (SD/SDHC/SDXC)
• Support Bus speed mode: Default speed(12.5MB/s), High Speed(25MB/s), and SDR50(50MB/s). SDR104 will be supported soon.
• Auto SD clock suspension for power saving
• Auto error checking function
  - Cyclic Redundancy Check (CRC16) for read transfer
  - CRC status check for write transfer
  - Timeout when no response returned from SD card
  - Timeout when SD card is not ready in time during initialization process
• High performance for data transfer by 4-bit SD data transfer mode
• Simple connection for command signal and FIFO interface for data signal
• No global clock and clock management inside it to reduce clock resource for RAID system.
• Reference designs available on ML505/ML506
  - High performance write/read transfer by raw data format (no file system).
  - Write/Read transfer in exFAT and FAT32 file system format.
