Swissbit S-55 and S-58 Series SD Memory Cards With Micron Flash Chips

Swissbit AG is expanding its range of industrial grade SD and microSD memory cards.

With reliability at their core, the S-55 and S-58 series integrate state-of-the-art technologies, making them a choice for demanding applications. The company accomplishes this by combining lindustrial grade 3D TLC NAND technology with a controller and firmware optimized for reliability.

The SD and microSD cards are available in capacities ranging from 16 to 512GB and support an extended temperature range of -40°C to +85 °C. The S-55 and S-58 series are based on Micron Technology, Inc. flash chips and complement the firm‘s existing S-50 and S-56 series, which use Kioxia 3D NAND. This provides company’s customers with a possible flexibility for the selection of a 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. For example, all cards are designed for temperatures ranging from -40°C to +85 °C and optimized to tolerate temperature fluctuations between read and write operations across the entire specified temperature range. This reduces servicing intervals and lowers the TCO.

Maximum reliability is also ensured by 120b 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 leveling. A molded SiP package with gold contacts completes the feature set, providing optimal protection vs. high mechanical stress and environmental influences even in harsh environments.

Capacity and compatibility
These 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 512GB, with the microSD version S-55u offering between 64 and 256GB choices.

The company continues to offer a 3D pSLC mode option with its S-58 series, which is suited for applications requiring extensive recording of small data blocks or constant high workloads. Along with capacities ranging from 16 to 128GB (S-58) and 16 to 64GB (S-58u), the pSLC versions provide up to 10x the longevity and up to 2x the speed.

Long-term availability and NAND architecture selection
With the release of the S-55 and S-58 series, the firm maintains its commitment to supplying memory cards of a high quality at competitive prices while assuring long-term availability. This is further underlined by the fact that the company offers NAND flash in its SD card portfolio from its 2 strategic partners, Kioxia and Micron. In addition to this series based on Micron’s 3D NAND, the firm already offers memory cards from its S-50/S-56 range fitted with Kioxia’s flash chips. While the performance specs and reliability advantages of both series are almost identical, the S-50/S-56 series is also available in capacities as low as 4GB. Additionally, this strategic alignment enables customers to frespond to short-term market fluctuations by ensuring the capacity to deliver at any.

With the range of ‘high reliability’ SD and microSD cards, the firm provides its customers with a great possible choice and planning security – as well as an opportunity to switch from legacy NAND technologies such as 2D MLC or SLC to the latest 3D TLC gen.
