Swissbit S-56u Memory Cards

Swissbit S-56u Memory Cards feature high performance, optimized Floyd–Warshall (FW) algorithm, high reliability, and controlled BOM. These memory cards are compliant with SD6.10 specification that includes SDHC/SDXC high-speed mode, 10/U3/V30/A2 speed class, SD2.0 backward compliant, and FAT32 / exFAT preformatted. The S-56u memory cards support SD SPI mode and the advanced Error Correction Code (ECC). The S-56u series operates at -40°C to +85°C industrial temperature range and 2.7V to 3.6V voltage range. These memory cards are available in 4GB, 8GB, 16GB, and 32GB.

Features

  • Optimized FW algorithms for read/write access, highest random write performance, and best endurance with long data retention
    • Designed for usage in applications with the highest requirements regarding reliability like data logging, POS/POI, medical, and other demanding use-cases
    • Suitable for intensive read/write operations
    • Advanced power-off reliability technology
    • Wear leveling technology
    • 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 occur
    • Data care management:
      • The interruptible background process maintain the user data for read disturb effects or retention degradation due to high-temperature effects
    • Near miss ECC technology:
      • Minimize the risk of uncorrectable bit failure over the product lifetime
    • Diagnostic features with lifetime monitoring tool support
  • High reliability
    • Optimized for a long life cycle that requires superior data retention because of the high-temperature mission profile
    • FW is designed to ensure the highest reliability at the lowest possible DPPM rates
