Industrial USB Module: UH110-UFM2

Apacer’s UH110-UFM2 is a high performance, embedded solid state drive (SSD) designed to replace a conventional IDE hard disk drive. As an embedded flash storage, UH110-UFM2 is compliant with USB 2.0 and backward compliable with USB 1.1.

Utilizing 3D NAND for capacity up to 64GB and providing more power efficiency than 2D NAND, UH110-UFM2 can be plugged into a standard Embedded USB connector commonly found in desktops, portable PC systems and industrial PC systems.

Regarding reliability, UH110-UFM2 is not only implemented with LDPC (Low Density Parity Check) ECC engine to extend SSD endurance and increase data reliability, but also equipped with SLC-liteX technology to offer higher number of P/E cycles up to 30,000 times.

In terms of flash management, UH110-UFM2 adopts the latest Page Mapping file translation layer and comes with various implementations including power saving modes, Wear Leveling, flash block management, power failure management, S.M.A.R.T. and Smart Read Refresh™.

UH110-UFM2 is well suited for embedded flash storage applications offering new and expanded functionality as well as more cost-effective designs, better performance and increased reliability.
