Industrial USB Flash Module (UFM)


The PS2251-03 UFM (USB Flash Module) supports USB 3.0, 2.0 and 1.1 interfaces to the NAND flash memory. This USB Flash Module is specially designed for motherboard and built-in to the PC/Notebook/IA system. By using this UFM solution, it will reduce a lot of efforts which was needed from R/D to production, as well as simplifying the RMA problems. It supports USB Mass Storage function and supports for USB boot function from BIOS. This solution provides not only easy to install, but also fast, easy to use and low cost way for user.
