Product Overview

Swissbit U-48 USB 2.0 embedded industrial USB flash drive module provides a robust, high performance, and reliable storage product with industry compatible interface and small form factor. The U-48 pSLC technology both enables high 3D TLC NAND flash operation and excellent endurance. Typical applications include data logging or boot drives for embedded application and netcom systems. The U-48 firmware includes data care management features which refresh storage areas that are not or only infrequently read. At high temperature operation these areas are prone to retention loss. The firmware monitors the state of the NAND blocks and refreshes those that show a high level of degradation, thus preventing uncorrectable errors. This is an important feature for USB flash drives that are used as read only boot media. The U-48 consists of a high performance 32bit RISC USB controller, the 10pin connector, power circuitry and different numbers of NAND dies.
