Swissbit’s USB Flash Drives are a high performance, reliable USB storage solution designed for embedded and industrial applications. With highly reliable SLC NAND flash in a fixed BOM incl. the FW configuration or pSLC or MLC version, Swissbit supports the longest possible stable supply. This reduces the risk and compatibility issues together with minimized requalification.
The new USB 3.1 products utilize a page based flash management which increases significantly the endurance and write performance.

Various effects like data retention, read disturb limits, or temperature can impact data reliability. The latest generation of Swissbit products use special methods to maintain and refresh the data for higher data integrity.
The Swissbit Life Time Monitoring feature enables users to access the memory device’s detailed Life Time Status and allows prediction of imminent failure, avoiding unexpected data loss. This feature uses an extended S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) interface or vendor-specific commands to retrieve the Flash product information.
The longevity product lines use special components with a long-term supply commitment of up to 10 years. These products offer lowest TCO in demanding applications with high requalification cost.
Intelligent Power Fail Protection and Recovery protects data from unexpected power loss. During an unintentional shutdown, firmware routines and an intelligent hardware architecture ensure that all system and user data will be stored to the NAND.
Robustness is one of our key specification targets. The design, assembly and use of selected materials guarantee an extremely solid design which has been validated by extensive testing.
The WAF (write amplification factor) for MLC-based products is reduced by combining a paged based FW block management with a powerful card architecture and configuration settings.
Sophisticated Wear Leveling and Bad Block Management ensure that Flash cells are sparingly and equally used in order to prolong life time of the device.
Swissbit‘s embedded memory and storage solutions are designed and approved for reliable operation over a wide temperature range. The products are verified at temperature corners and prestressed with a burn-in operating functional test (Test During Burn In – TDBI).
