Hyperstone Introduces S8 Line of Flash Memory Controller

Hyperstone
GmbH introduces its S8
– SD/MMC flash memory controller.

It’s targeting applications such as
SDHC, SDXC, SD, smartSD, smart microSD, high speed and UHS-I memory
cards as well as eoMMC MCP modules. Together with the company’s
proprietary hyReliability firmware, it provides endurance and data
retention management, as well as fail-safe features, all of which are
mandatory for industrial applications.

Product Highlights:

• Compliant to SD 3.0 (UHS-I) and SD 2.0
  specifications

• CPRM and ASSD 2.0 or Mc-EX support

• Compliant to eoMMC 4.41 with additional
  support for Power-Off Notification, Discard, and Sanitize possible

• Host transfer rate of up to 104 MB/s

• ECC engine correcting up to 96-Bit,
  ample hardware resources to support next flash generations

• Flash interface compliant with Toggle
  DDR and ONFI 2.3

• Sequential read and write up to 90 MB/s

• On-the fly AES encryption hardware
  engine

• Additional SDIO 3.0, SPI, I2C, and
  ISO7816 interfaces

• hyReliability flash memory management
  and firmware architecture

• Static and global wear leveling to
  maximize write endurance

• Read disturb management and dynamic
  data refresh to maximize data retention and refresh data subject to
  read disturbance

"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," said Axel
Mehnert, VP marketing, Hyperstone. "Our mission is enabling
future NAND flashes and advanced technologies, fit for use especially
within industrial, ruggedized 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." said Dr. Jan Peter
Berns, MD, 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 be available as Probed Die and
in an LGA-52 package. Samples are available.
