Flash memory card controller for industrial applications

 

The S8 SD/MMC flash memory controller, launched by Hyperstone, is suited for applications such as SDHC, SDXC, SD (SecureDigital), smartSD, smart microSD, high speed and UHS-I memory cards as well as e•MMC MCP modules.

Together with Hyperstone’s proprietary hyReliability firmware, it provides enhanced endurance and data retention management, as well as rigorous fail-safe features, all of which are mandatory for industrial applications. The S8 is fully compliant to SD 3.0 (UHS-I) and SD 2.0 specifications, as well as e•MMC 4.41 with additional support for Power-Off Notification, Discard, and Sanitise.

The controller provides a host transfer rate of up to 104MB/s, sequential read and write speeds of up to 90MB/s, and ECC engine correcting up to 96-bit, supporting next-generation flash. It features read disturb management and dynamic data refresh in order to maximise data retention and refresh data subject to read disturbance.

Axel Mehnert, Vice President of Marketing, Hyperstone, commented: “Our new S8 SD/MMC controller is designed to deliver the highest level of reliability and data retention when using most recent 1x nm MLC flash technologies. Tying the possibly strongest BCH ECC to our proven hyReliability firmware architecture is necessary to ensure highest level of endurance and reliability that our customers are used to. Our mission is enabling future NAND flashes and advanced technologies, fit for use especially within industrial, ruggedised applications.”

“Besides industrial SD applications, which require highest reliability and ruggedness, the additional SDIO 3.0 and ISO 7816 interfaces as well as the on-the-fly AES encryption make it well suited for additional applications in the security and identification field,” added Dr. Jan Peter Berns, Managing Director, Hyperstone. “We have implemented hardware features and developed firmware to provide highest data retention and refresh mechanisms even when memory cards are faced with extreme environmental conditions. Such features are inevitable for memory systems used outdoors and can prevent in-car infotainment systems from failing.”

S8 will initially be available as Probed Die and in an LGA-52 package. Samples are available immediately.
