New industrial SD memory card controller with extended security features

10-03-2022 | Hyperstone | Semiconductors

Hyperstone has released its new S9 family of SD and microSD memory card controllers. In the tradition of its aspiration to offer the most reliable NAND flash controllers, the family satisfies the needs of demanding applications with turnkey firmware. Also, the S9S version of the controller, with an API, adds various security features.

The controller’s FlashXE ECC and hyReliability feature set ensure extended endurance, data integrity, and power fail safety, coping with demanding applications in markets including industrial automation, networking, telecom, and medical equipment. With the hyMap flash translation layer, the S9 provides minimal write amplification and maximum endurance, which enables efficient use of 3D NAND flash, resulting in the lowest field failures over time. With the company's complementary hySMART lifetime and health monitoring tool, qualification can be monitored, and predictive maintenance enabled.

The security variant S9S provides hardware support for AES-128/256, Public Key Elliptic Curve Cryptography, TRNG/DRBG and SHA-256 hashing, and GPIO pins ISO7816, I2C and SPI interfaces. The API delivers the infrastructure and tools to create a genuinely innovative storage solution.

“We see the demand for individual solutions and the need for customised, unique products now more than ever,” said Katrin Wenzel, technical marketing manager at Hyperstone. “The S9 comes with various options to adjust the firmware, add unique code and attach other external components to enable truly innovative products. At Hyperstone, we have a tradition of supporting the development of innovation and differentiated SD and microSD card products. From design tools to full manufacturing services of System-in-Package (SiP), chip-on-board (CoB) and bare-die based products like microSD, we can provide any service needed.”

With an extensive network of design partners and in-house manufacturing capabilities, the company can also support and facilitate the sourcing of NAND flash and manufacturing of SD or microSD memory cards.

The S9 has been qualified for the industrial temperature range (-40C to +85C) and will be available in a 7.5mm x 4mm LGA-64 package, S9-LAK08 (standard version) and S9-LASK08 (security and API version). SD cards for evaluation, and engineering samples and firmware, are available now.
