Swissbit's S-220 Series SD memory card is a small-form-factor, non-volatile memory card which provides high-capacity data storage. Its aim is 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 card operates in two basic modes, SD card mode and SPI mode. 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 and 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 their lifetime. The hardware RS-code ECC allows to detect and correct 4 symbols per 528 Bytes. The S-220 series memory card has a voltage detector and a powerful power-loss management feature to prevent data corruption after power-down.
