Industrial microSD uSD Memory Cards
Industrial microSD Memory Cards
The Delkin Industrial microSD Memory Card is a high-endurance NAND flash storage solution for industrial applications that utilizes the Secure Digital interface. Delkin offers industrial-grade high endurance SLC NAND flash solutions in the U300 Series, U330 Series, and U331 Series, and Commercial cost-effective MLC NAND flash versions in the Utility and Utility+ Series. Every Delkin Industrial microSD card features a controlled Bill of Materials (BOM), Life Cycle Management, outstanding applications support, and strictly adheres to the specifications set forth by the Secure Digital Association.
While microSD cards primarily began in 1999 as a storage medium for portable consumer devices like mobile phones, GPS systems, and dash cameras, key characteristics such as small size, low power consumption, high reliability, and simplicity of integration also make the form factor an ideal fit for many industrial applications with constrained real estate.

Industrial microSD Speed Classes & Bus Interface
Delkin Industrial microSD Memory cards are classified as Normal Speed, High Speed, or Ultra High Speed (UHS-I or UHS-II). These classifications are differentiated by the Bus Speed of each card, with indicates the maximum theoretical read and write speed capability. Similarly, each card has a speed class that is designated by the SD Association, which is based on the minimum sequential write speed that the card performs at. While theoretical speeds can be quite high, actual card speeds are usually lower and vary by card configuration, the operation being performed, how the data on the card is organized, and the host device.
