FAQs about OEM microSD Cards

For OEMs and embedded computing designers, juggling the need for industrial grade reliability with budgetary demands is a challenge. A middle-ground solution like the utility microSD from Delkin combines the affordability of commercial products with the reliability of an industrial grade OEM microSD card.

 

Why choose a microSD instead of a full-size version?

As the push to make electronics in ever smaller and thinner sizes has taken hold, the need for small but powerful storage solutions has increased. For the OEM space, the demand for micro-sized storage has outpaced the demand for all other types of memory cards. Although microSD cards were initially intended for use only in small, mobile electronics, this form factor’s use has grown exponentially across a multitude of devices and applications, thanks to its reliability, simple integration, low power demands, and of course, its small size.

 

 

What are the technical specifications for microSD cards?

Although industrial grade microSD cards with SLC Flash are available, OEMs frequently gravitate towards utility microSD for its cost-effective reliability. With utility microSD cards, you can expect:

 

  • 4GB to 64GB capacity
  • MLC Flash
  • -25 to 80 degrees C operating temperature, or -40 to 85 degrees C operating temperature with Utility+
  • 95MB/s read and 90MB/s write speeds
  • 5 year data retention
  • > 3 million hours MTBF (at 0 to 30 degrees C)
  • SMART feature compatibility

 

In addition to these high-performance technical features, utility microSD cards come with a controlled BOM, so OEMs can be confident that part changes will not happen unexpectedly and impact usability. When part changes are necessary, a new product number will be issued and advanced notice will be given so that final orders can be placed. The cards adhere to all the specs set forth by the Secure Digital Association, and are backed up with careful Life Cycle Management protocols.

 

Can microSD cards be customized?

All microSD cards are fully customizable to meet host-specific parameters and application-specific operations. Custom features like laser etching, pad printing, packaging, formatting, and data loading are also available. For OEMs, this allows for the maximum degree of personalization at a cost-effective price point, without the fear of uncontrolled BOMs rendering devices and applications useless without warning.
