Secure Digital (SD) memory cards have a widespread use in industrial and automotive applications, ranging from read only applications as in navigation systems to utilization as boot media, for video recording or data logging. Swissbit’s Industrial Secure Digital (SD) card series are designed for high sustained performance and endurance and are manufactured and tested in Swissbit‘s own fab to withstand extreme environmental conditions.

The SLC based S-600 / S-250 offers highest endurance and were recently introduced to offer increased longevity. The new S-52 targets automotive and video recording applications while S-50 /S-55 targets typical high reliability use cases as seen in industrial environments. The 3D pSLC versions S-56 and especially the high endurance S-58 cards offer best cost/endurance ratio.

Data Care Management

Various effects like data retention, read disturb limits, or temperature can impact data reliability. The latest generation of Swissbit products use special methods to maintain and refresh the data for higher data integrity.

Electrostatic discharge and electromagnetic interference
ESD and EMI safe

The product designs are in line with the latest regulations for electrostatic discharge and electromagnetic interference. Swissbit strives to exceed these limits with our own in-house technology and production capabilities, for example with System-in-Package (SiP) competence.

Life Time Monitoring (LTM)
Life time monitoring (LTM)

The Swissbit Life Time Monitoring feature enables users to access the memory device’s detailed Life Time Status and allows prediction of imminent failure, avoiding unexpected data loss. This feature uses an extended S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) interface or vendor-specific commands to retrieve the Flash product information.

Longevity
Longevity

The longevity product lines use special components with a long-term supply commitment of up to 10 years. These products offer lowest TCO in demanding applications with high requalification cost.

Power Fail Protection & Recovery
Power fail protection

Intelligent Power Fail Protection and Recovery protects data from unexpected power loss. During an unintentional shutdown, firmware routines and an intelligent hardware architecture ensure that all system and user data will be stored to the NAND.

Shock & Vibration
Shock and vibration

Robustness is one of our key specification targets. The design, assembly and use of selected materials guarantee an extremely solid design which has been validated by extensive testing.

Write Amplification Factor
WAF reduction

The WAF (write amplification factor) for MLC-based products is reduced by combining a paged based FW block management with a powerful card architecture and configuration settings.

Wear leveling
Wear leveling

Sophisticated Wear Leveling and Bad Block Management ensure that Flash cells are sparingly and equally used in order to prolong life time of the device.

Wide temperature support
Wide temperature support

Swissbit‘s embedded memory and storage solutions are designed and approved for reliable operation over a wide temperature range. The products are verified at temperature corners and prestressed with a burn-in operating functional test (Test During Burn In – TDBI).

White Paper SD Express

In June 2018, the SD Association, responsible for setting SD memory card standards, released a specification for SD Express memory cards for the first time. This specification enables the cards to achieve data transfer speeds of nearly four gigabytes per second. This performance boost is made possible by incorporating PCIe 4.0 and NVMe interfaces, commonly found in solid-state drives.

The introduction of this new SD card variant signals an upcoming competitive showdown between the established standard and its successor. This white paper aims to provide an unbiased comparison between the two SD representatives and offer valuable decision support.
