    Device Utilization and Performance

    Large-Capacity: Up to 2TB Fast Transfer: Up to 104MB/s Actual measured value: Read:95.7MB/s/ White84.9MB/s (Approx. 2 to 4 times faster than USB2.0.)

    Getting Started

    This is a controller that manages data transfer through an SD card. This Product is embedded for use in FPGA or ASIC. SDHC memory cards adopted FAT32 as a file system. FAT32 complied with the standards but its max capacity was limited to 32GB However, the emergence of digital cameras with over 10,000 pixels and High definition (HD) video or filming functions requires larger capacity and faster transfer speeds. Therefore, SDXC standards were designed. They support 2TB at max capacity and have adopted exFAT as a file system. In order to realize faster transfers, UHS-I standards were also chosen. The transfer speed was improved from the previous maximum of 25MB/s to 104MB/s (The transfer rates above are theoretical figures). This product supports both SDXC and UHS-I.
