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 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 SLC SD and Extended Life Cycle (ELC) SD cards, as well as Utility SD and microSD cards, which are cost-effective MLC options for OEM applications.

SD / SDHC / SDXC
Delkin Devices’ full-size SD cards utilize a true industrial controller and SLC flash to deliver a rugged, high endurance solution for applications that are write intensive, subject to extreme environmental conditions or which require long term field reliability when recording mission critical data.
Utility SD / microSD
Delkin Devices developed the Utility concept for OEM’s and embedded designers that need a cost-effective, yet controlled storage solution. In many cases, the cost of the host and the usage model does not support the use of high-endurance SLC flash, yet the application still requires an industrial-grade product, consistent performance and life cycle management.
