Swissbit's SD memory card is a small form factor, non-volatile memory card which provides high capacity data storage. It is aimed to capture, retain, and transport data, audio and images, facilitating the transfer of all types of digital information between a large variety of digital systems. The SD memory card also supports SD high speed mode with up to 50 MHz clock frequency. The cards are compliant with SD memory card specification Part 1, physical layer specification V2.00 SD memory card specification Part 2, and file system specification V2.00. The card has an internal intelligent controller which manages interface protocols, data storage and retrieval, as well as hardware RS-code error correction code (ECC), defect handling, diagnostics and clock control. The wear leveling mechanism assures an equal usage of the flash memory cells to extend the life time. The hardware RS-code ECC allows the card to detect and correct 4 symbols per 528 bytes. The card has a voltage detector and a powerful power-loss management feature to prevent data corruption after power-down.
