New Swissbit SD and Micro SD memory cards with extremely long data retention

News

Swissbit AG presents its new S-40 and S-40u Series SD and Micro SD memory cards for TCO-optimised applications.

These are the first SD and Micro SD cards on the market to feature autonomous data refresh that requires no intervention by the host or application. Thanks to intelligent algorithms, the memory cards deliver up to one hundred times longer data retention than conventional SD memory cards. S-40 (SD) and S-40u (Micro SD) memory cards are equipped with intelligent read disturb management (RDM) alongside an autonomous, performance-neutral background “auto refresh” process.

This type of data care management significantly improves data reliability and balances out the increasing limitations of MLC NAND flash during long operation time and extensive use in the field. Data transfer rates reach up to 11 MB/s for write and up to 24 MB/s for read operations, putting them into SD3.0 speed class 6. Diagnostic functions offering highly detailed status information plus standalone data maintenance guarantee data retention for many years, even in especially rough environmental conditions and in extreme temperatures. S-40 (SD) and S-40u (Micro SD) memory cards prevent read disturb bit errors even in intensive read applications. Users benefit from the shortest possible downtimes thanks to an extended operating life in the field and extraordinarily long data reliability.

Selected hardware, materials and production processes in automotive conditions ensure that the SD and Micro SD cards are of the highest quality. The high-performance controller offers the best ECC (error correction code) on the market which employs modern firmware architecture and supports future MLC generations. The firmware can be updated as required. Swissbit’s S-40 and S-40u series have been optimised for the most challenging applications where data is primarily called up for reading, such as automotive/navigation, infotainment and POI/POS applications. S-40 SD cards are available up to 32 GB; S-40u Micro SD cards are available from 4 GB up to 16 GB. Depending on the project size, Swissbit is able to realise customer-specific modifications with virtually no limitations.
