SD Controllers for NAND Flash Solutions

SD & eMMC Controllers for Industrial NAND Flash Applications

Reliable SD, microSD & eMMC Controllers for Industrial NAND Flash Storage Solutions

SD, microSD & eMMC based NAND Flash Memory Contollers for SD and microSD cards, embedded SD solutions and eMMC applications

Hyperstone offers a range of highly reliable SD, microSD and eMMC NAND flash memory controllers for an array of industrially embedded storage solutions. Secure Digital has taken over many CF applications since 2012 and is now used in systems like PLC, Motion Controllers, HMI and SBC. These systems are then implemented across automation systems, robots and mobile applications, whilst also securing operations in transportation manufacturing plants. SD solutions can work as fixed or removable drives. They can serve as a boot drives as well as storage for customer data. For the past few years, SD cards are also used as mass storage for Infotainment systems in cars replacing HDDs. Their main purpose is mapping storage, which requires special flash handling and ultimately a highly reliable controller.

Formerly used in mobile phones, eMMC has now found itself stepping into the Industrial market and a range of automotive applications. In Automotive applications it functions similarly to an SD card whereas Industrial applications place their focus on raw-NAND and NOR replacements. As eMMC can only serve as a fixed drive it is restricted to internal use. An eMMC solution is based on a BGA package which needs to be soldered to the board. As firmware and user data is generally stored on the eMMC before soldering measures have to be taken to refresh data thereafter. Hyperstone offers the controller only but can provide access to module makers.
