Swissbit said that it has combined industrial grade 3D TLC NAND technology with a powerful controller and firmware optimised for maximum reliability. The SD and microSD cards are available in capacities ranging from 16 to 512 GB and support an extended temperature range of -40 to +85 °C.
The S-55 and S-58 series are based on Micron flash chips and complement Swissbit's existing S-50 and S-56 series, which use Kioxia 3D NAND. This provides Swissbit customers with greater flexibility when it comes to the selection of the most suitable cards for specific requirements and applications.
The SDHC/SDXC S-55 and S-58 series provide all the prerequisites for their intended applications in areas such as data logging, IPCs, HMI units, POS/POI terminals, and medical and surveillance applications. All cards, for example. are designed for temperatures ranging from -40 to +85 °C and are optimised to tolerate temperature fluctuations between read and write operations across the entire specified temperature range. This reduces servicing intervals and lowers the total cost of ownership (TCO).
Maximum reliability is also ensured by 120bit LDPC error correction, full page fail protection, read disturb management, background data refresh, data recovery following a sudden power loss, and sophisticated static and dynamic wear levelling. A moulded SiP package with gold contacts completes the feature set, providing optimal protection against high mechanical stress and environmental influences even in harsh environments.
The new memory cards are SD-6.1 compliant and support both the common SPI interface mode in embedded systems and the UHS-I interface mode. They reach UHS speed class U3 or respectively speed class 10, as well as application class A2 and video speed class V30
The S-55 is available in capacities ranging from 64 to 512 GB, with the microSD version S-55u offering between 64 and 256 GB choices.
Swissbit continues to offer a 3D pSLC mode option with its S-58 series, which is well-suited for applications requiring extensive recording of small data blocks or constant high workloads. Along with capacities ranging from 16 to 128 GB (S-58) and 16 to 64 GB (S-58u), the pSLC versions provide up to ten times the longevity and up to twice the speed.
