The AU6989 USB 2.0 Flash Disk Controller is the best high performance solutions for SLC (Single- Level Cell), MLC (Multi-Level Cell) NAND and AG-AND with multiple dies data flash. Its high-speed read (30MB/Sec) and write access performance enable users to transfer and backup data effectively. Besides, AU6989 is certified by USB-IF (USB Implementers Forum), WHQL (Window Hardware Quality Labs) and EMI tests to guarantee the quality and reliability for end-users.

With multiple functions integrated into one chip and external components built inside, AU6989 is pledged to deliver the best performance benchmark and to further reduce the BOM cost of end products adopting this solution. It provides dual channel access and ISP (In-System Programming) technologies, which are the most important features to allow manufacturers building high performance UFD easily and to have the flexibility of adopting different source of flash chips.
