eUSB

A Low-Cost Embedded Storage Option

Our eUSBs are complete solutions for embedded boot-up applications. They’re smaller, more durable, and easier to design in than HDDs.

starting lineCompetitive Advantages for Solid State Designs

Rugged, reliable, cost-effective, and small, Micron's RealSSD™ devices are designed to give our customers a choice in embedded data storage. And these embedded USBs are a better choice than hard disk drives (HDDs)—for many reasons.

Our eUSBs are a lot smaller, more durable, and easier to design in than HDDs. They combine flexibility, performance, and fast time-to-market, and they cost less than traditional HDDs.

Micron is known for advanced and innovative technology, and our eUSBs are a great example of a better, faster, and less expensive NAND solution that offers distinct competitive advantages for solid state designs. Use our Web site to find out all you need to know about designing one in to your embedded, boot-up application.

Embedded USB Part Catalog and Documentation


Reliability in Harsh Environments
With no moving parts, the reliability of our RealSSD eUSBs far surpass many of the best-in-class, rugged HDDs. They can sustain 500G shocks and operate within extended and industrial temperature ranges.

Cost-Effectiveness and Space Savings
eUSBs offer the right densities at the right price, and they do it in a package that’s smaller than a 1.8-inch HDD. Gone are the days of paying for more capacity than you need for your embedded boot application and wasting valuable space that could be devoted to advanced features.

Other Key Benefits

Cost Effectiveness
Costs less to implement than even the least expensive HDDs.

Small Size
Smaller than a 1.8-inch HDD, an embedded USB lets you pack more features into less space.

Reliability
Withstands extreme shock and vibrations and has a wider operating temperature range than competing technologies, ensuring higher reliability in demanding environments.

Low Power
Draws less than 330mW of power when actively reading or writing data.

Can I use the eUSB as a boot device?
Yes, Micron’s eUSB can be used as the Operating System boot and main storage device. The application’s BIOS must support this feature. This isn’t a concern for most systems that have been manufactured in the last five years and support USB 2.0. In either the main storage or boot mode, the eUSB is recognized as a fixed hard drive in the system.
How does the eUSB attach to my system board?
The eUSB device has a 10-pin (2x5) USB female connector compatible with the industry standard 10-pin connector found on most motherboards today. A mounting hole is also provided on the PCB to provide for a stable connection to the system board.
Is it possible for me to secure the data on Micron’s eUSB product?

No, Micron’s RealSSD eUSB does not support any security features.

Does Micron provide a way for me to retrieve Flash ID information to determine the useful life remaining on the device?
Yes, there is a tech note available upon request to Micron Sales and Support. This document provides commands that enable the host controller to retrieve Flash ID information with regards to bad block count, spare block count, erase count, and FlashIDBuf data. This data can be used to help determine the useful life of the eUSB.
Does Micron offer the eUSB with a 3.3V option?

Yes. Please check the part catalog for Micron’s offering.
