Reliable SD memory card for industrial applications

The new S-5x range comprises the S-50 SD and S-50u micro SD memory cards at a very competitive price point, alongside the high-endurance S-56 & S-56u versions which use 3D pSLC mode to achieve a tenfold increase in endurance. All support a full temperature range from -40 to +85°C.

“The new Swissbit S-5x cards have been optimized to tolerate dynamically changing temperatures between write and read cycles (cross temperature) across the entire range. That’s precisely where Swissbit adds value when it comes to extended service intervals and reduced total costs of ownership. It gives our customers a clear competitive edge over other vendors,” said Roger Griesemer, General Manager of the Memory Solutions division at Swissbit.

Other reliability features include 120b LDPC error correction (Low Density Parity Check Error Correcting Code), a full-page-fail protection mechanism, read disturb management, background data refresh, sudden power loss recovery, sophisticated static and dynamic wear levelling and – for mechanical protection – a moulded SIP package with a 30µ" thick gold connector.

All these features combine to form a highly reliable device with the lowest DPPM rates in the market – a position already proven by existing industrial SD memory cards from Swissbit.

The firmware architecture supports fast write bursts and, in combination with the other FW features, makes this series ideal for high read / write traffic that typically occurs in data logging, IPCs, HMI units, POS/POI, medical and surveillance applications.

The S-50 SD memory card is initially available in capacities from 16GB to 256GB, while the S-50u range extends from 16GB to 128GB.

Where high endurance is required due to intense small block data logging or high traffic, then the S-56 & S-56u will deliver with its pSLC technology. The density range for these new cards is from 4GB to 64GB for the S-56, with 4GB to 32GB for the S-56u model.

Swissbit plans to add higher capacities for all variants later.

All memory cards across the new range are compliant to the SD 6.1 specification and fully support SPI mode. They reach up to UHS U3, speed class ten, and the A2 and VSC30 application classes.

The S-5x products are supported by the Swissbit Life Time Monitor that provides detailed usage information, allowing easy prediction of the expected lifetime under real world applications.
