Swissbit S-50 and S-56 SD and microSD Industrial Flash Card Series With 3D NAND

Swissbit AG has extended its range of industrial SD memory cards with purposeful products: the S-50 and S-56 series.

Based on industrial grade 3D NAND technology, theses products integrate flash chips with a controller and firmware, which is aimed at delivering high reliability within a robust housing. They are manufactured in the company’s own IATF 16949 certified fab.

Reliable across complete temperature range
The S-5x range comprises the S-50 SD and S-50u micro SD memory cards at a competitive price point, alongside the endurance S-56 and S-56u versions which use 3D pSLC mode to achieve a tenfold increase in endurance. All support a temperature range from -40°C 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“, says Roger Griesemer, GM, memory solutions division.

Quality thanks to modern technology
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 leveling and – for mechanical protection – a molded SIP package with a 30µ thick gold connector.

All these features combine to form a reliable device with low DPPM rates.

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.

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

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

The company plans to add higher capacities for all variants later.

All memory cards across the new range are compliant to the SD 6.1 spec and support SPI mode. They reach up to UHS U3, speed class 10, and the A2 and VSC30 application classes.

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