Hyperstone S9 Family of SD and microSD Memory Card Controllers

Hyperstone GmbH introduces a S9 family of SD and microSD memory card controllers.

In tradition of the company’s aspiration to provide a reliable NAND flash controllers, the S9 meets the requirements of demanding applications with turnkey firmware. Additionally, the S9S version of the controller, with an API, adds various security features.

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

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

There are billions of devices providing an SD or microSD card slot and interface; making it one of the most widely available options to add removable storage to any application. The interface and form factor can be used to add features such as security, authentication, secure data logging (WORM), surveillance, addition of wireless connectivity such as NFC, Bluetooth and more.

“We see the demand for individual solutions and the need for customized, unique products now more than ever,” said Katrin Wenzel, technical marketing manager. “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 a network of design partners and in-house manufacturing capabilities, the company can also support and facilitate sourcing of NAND flash and manufacturing of SD or microSD memory cards.

The S9 has been qualified for industrial temperature range (-40 to +85 °C) and will be available in a 7.5x4mm LGA-64 package, S9-LAK08 (standard version) and S9-LASK08 (security and API version).

SD cards for evaluation as well as engineering samples and firmware are available.
