## **Product Features** 

- High performance 6.10 specification 

   - SD burst up to 104MB/s 

   - SD Normal speed 0…25MHz clock rate 

   - SD High speed 25…50MHz clock rate 

   - SD UHS-I speed 0...50MHz (DDR) and 0…208MHz (SDR) 

- Power Supply: (Low-power CMOS technology) 

   - 2.7…3.6V normal operating voltage 

- Optimized FW algorithms especially for read/write access, highest random write performance and best endurance with long data retention. 

   - Designed for usage in applications with highest requirements regarding reliability like data logging, POS/POI, Medical and other demanding use-cases. 

   - Especially suitable for intensive read/write operations 

   - Advanced power-off reliability technology 

   - Wear Leveling technology 

      - Equal wear leveling of static and dynamic data. The wear leveling assures that dynamic data as well as static data is balanced evenly across the memory. With that the maximum write endurance of the device is guaranteed 

   - The S-50 High Reliability Series is optimized for high read/write traffic for demanding industrial applications. 

   - Read Disturb Management 

      - The read commands are monitored and the content is refreshed when critical levels have occurred
