Product Description

The perpetual drive to shrink electronics has made the tiny microSD form factor the fastest growing segment in the industrial and OEM space in recent years.  Since microSD cards are constructed as an encapsulated SIP (System In Package), they are also extremely rugged from a mechanical standpoint, able to withstand environments subject to shock and vibration. Whether just 512MB is needed to boot an application or 16GB is needed for extensive data logging, Delkin has a high endurance SLC microSD option available, rated for full industrial temperature operation.  Configurations are also available with SMART capability, allowing users to monitor the status of the card, including program/erase cycles consumed, spare block status, power cycles and an estimated remaining life. Delkin provides a dashboard tool for off-line SMART monitoring or the card data can be accessed directly via a library or SD commands.

As contrasted with commercial grade microSD cards, which can have frequent configuration changes to reduce cost, or which often utilize TLC flash, Delkin U300, U330 & U331 Series Industrial microSD cards are controlled with a locked bill of materials.  This means that no changes can be made to the flash, controller or firmware configuration without a part number change. Delkin also understands the importance of life cycle management, so that when a part must be discontinued, users are notified in advance, offered a last time buy opportunity and provided with qualification samples of the replacement part.

Delkin offers customization of microSD’s, including custom pad printing or content loading, and the cards are available with adapters converting them to full size SD.

In addition to industrial microSD, Delkin also offers full-size D200 SD & D200 ELC Extended Life Cycle SD cards, as well as Utility SD and microSD cards, which are cost-effective MLC options for OEM applications.
