Description

The latest SD memory card series S-30 and S-50 are based on 3D NAND TLC and offer best cost efficiency. The S-30 is targeting highly cost sensitive read mostly applications while the S-50 is a true industrial SD Card for all use cases. For high endurance demand the pSLC version S-56 is the ideal solution. These cards support Class 10, U3 mode.

The continued series S-45 (MLC version), S-46 (pSLC version), S-450 (SLC version) and S-455 (SLC version) include the same set of sophisticated features and, through the implementation of UHS-I, support data transfer rates of up to 90 MB/s. The combination of MLC (Multi Level Cell) NAND Flash with an industrial controller and page based firmware technology enables prolonged data retention and extended life cycles despite the write endurance limitations of MLC Flash. The S-45, S-46 and S-455 SD memory cards excel with a random write data rate of up to 1400 IOPS.

The special firmware features in the latest series include a powerful built-in Error Correction, Read Retry, Autonomous Data Care Management, Life Time Monitoring & diagnostic features, Randomizer, Wear Leveling & Bad Block Management algorithms and intelligent Power Fail Protection.

All Swissbit SD Cards can withstand extreme environmental conditions. They provide the highest level of mechanical stability and enhanced ESD protection. Furthermore, the hard gold SD connectors endure a minimum of 20,000 insertion cycles.
