セキュア デジタル (SD) メモリ カードは、ナビゲーション システムなどの読み取り専用アプリケーションから、ビデオ録画やデータ ロギング用のブート メディアの用途、また産業および自動車アプリケーションで広く使用されています。 Swissbit の産業用セキュア デジタル (SD) カード シリーズは、高い持続的パフォーマンスと耐久性に最適化されて設計されており、過酷なな環境条件に耐えられるよう、Swissbit の自社工場で製造およびテストされています。
SLC ベースの S-600μ / S-250μ は最高の耐久性を実現し、書き込み耐久性に優れています。 新しい S-52μ は自動車およびビデオ録画アプリケーションをターゲットとし、S-50μ /S-55μ は産業用途の高信頼性ユースケースをターゲットとしています。 3D pSLC バージョン S-56μ、特に高耐久性 S-58μ カードは、最高のコスト/耐久性比を提供します。

Swissbit offers a special protective coating on selected products. This coating is a thin polyurethane film that protects against aggressive environmental conditions such as dust, moisture, or corrosive gas.
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.
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.
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.
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.
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.
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.
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.
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.
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).
