Memory cards cope with challenging applications

The new S-450 and S-450µ series SD and Micro SD memory cards from Swissbit are aimed at demanding applications requiring high reliability and robustness. They combine SLC flash components with a powerful system architecture and intelligent firmware. The new memory cards are available at distributor Rutronik.

The S-450/S450µ cards comply with UHS-I bus mode, speed class 10 and offer a sequential data rate up to 90MB/s for reads and 75MB/s for writes. Swissbit’s intelligent algorithms enable the memory cards to deliver up to one hundred times longer data retention than conventional SD memory cards.

They are optimised for the most challenging SD applications where a high percentage of write operations occur and where data retention at maximum program-erase (PE) cycles are required.

They are designed for boot code execution, data logging, and transaction packet storage. Equipped with intelligent read disturb management (RDM) alongside an autonomous, performance-neutral background “auto refresh” process, the memory cards provide data reliability beyond the already high levels achieved by SLC.

Thanks to a combination of fast flash devices and powerful controller, these complex management tasks can be achieved efficiently. This keeps system utilisation under all conditions well below the specified limit, allowing a high sustained IOP rate and guaranteeing compatibility with a wide range of industrial and networking applications.

The high-performance controller offers the best ECC on the market, Power fail safety is achieved by transaction log based firmware. S-450 and S450µ memory cards prevent read disturb bit errors even in intensive read applications.

Users benefit from the shortest possible downtimes due to an extended operating life in the field and long data reliability. The SD/ micro SD cards operate in commercial (0°C up to +70°C) and in industrial (-40°C up to +85°C) temperature ranges as well as in especially rough environmental conditions.
