Swissbit S-55u Industrial MicroSDXC Memory Cards

Swissbit S-55u Industrial MicroSDXC Memory Cards feature equal wear leveling of static and dynamic data so that data is balanced evenly across the memory. These memory cards offer optimized FW algorithms for read/write access, impressive random write performance, and endurance with long data retention. The S-55u memory cards utilize advanced power-off reliability technology and wear-leveling technology. The read disturb management feature of the memory cards monitors the read commands and the content is refreshed when critical levels have occurred. These memory cards run an interruptible background process to maintain the user data for read disturb effects or retention degradation due to high-temperature effects. The near-miss ECC technology minimizes the risk of uncorrectable bit failure over the product lifetime.

The S-55u memory cards operate within 2.7V to 3.6V voltage range and -40°C to 85°C industrial temperature range. These memory cards are available in 64GBytes, 128GBytes, and 256GBytes capacities. The S-55u memory cards offer sequential read up to 97MBytes/s and
sequential write up to 60MBytes/s.
