The embedded USB drive is an ideal solution for applications that require low cost and high reliability. Typical applications include PC caching and boot drives for embedded computing, server, and networking systems. High performance, reliability, and easy implementation make Micron embedded USBs an ideal storage solution. To consistently deliver the best possible performance, the embedded USB uses only SLC NAND Flash, and all densities use two x8 NAND channels to the controller. In addition to being fast, SLC NAND Flash offers solid reliability, coupled with ECC and wear leveling. The USB system interface is widely available in many system designs and is easy to implement, enabling rapid time to market. The embedded USB consists of two TSOP-packaged Micron NAND Flash components, a USB controller, and a 10-pin USB connector on a PCB. Different densities are available depending on the number of die in each package and the density of each NAND Flash die. The drive operates at 5V ±5% or 3.3V ±5%. It uses industry-standard 10-pin connectors and supports USB Specification, Revision 2.0. It is also backward compatible with Revision 1.1 and can be used with operating systems that support USB Mass Storage Class Specification, Revision 1.0.

It uses various combinations of hardware-based error correction algorithms and firmware-based wear-leveling algorithms. Over the life of the drive, uncorrectable errors may occur. An uncorrectable error is defined as data that is reported as successfully programmed to the drive, but when it is read out of the drive, the data differs from what was programmed. See the Uncorrectable Bit Error Rate Table. The mean time between failures (MTBF) can be predicted based on component reliability data obtained by following the methods referenced in the Telecordia SR-332 reliability prediction procedures for electronic equipment.
