Introduction 1.1 Description The AU6984 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, AU6984 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, AU6984 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. Same as its siblings of product family, AU6984 features the auto-run function to prompt the designated AP automatically when plugging into PC. In addition to being as a removable storage device, AU6984 can also be configured as a bootable disk for system recovery. Also, its random access performance exceed the minimum requirement of Read Boost feature found in Microsoft Vista operating system, in which randomly access blocks of information are saved into UFD for boosting up the average performance. To enhance the usefulness and manageability of UFD further, Alcor Micro develops a smart application program iStar (Partition/Password Operation Tool) as a handy utility in managing partition, password and security. Having iStar as the companion of UFD, the data in a UFD could be protected from unauthorized access successfully. 1.2 Features PCBs are pin compatible in AU6980, AU6981, AU6982, AU6983, AU6984. Integrate build-in regulator Supports SLC and MLC dual channel with high performance Supports 4K/Page SLC and MLC dual channel with high performance Integrates hardware DMA engine to tune up the operation performance Improve read performance reach 30MB/Sec Supports firmware upgrade mechanism(ISP,In-System Programming) Integrates hardware DMA engine to tune up the operation performance Integrates multi-bit ECC correction mechanism Complies with the standards defined in USB v2.0, USB Device Class Definition for Mass Storage and Bulk-Transport v1.0 Works with default driver under the environments of Windows ME, Windows 2000, Windows XP, Mac 9.2, Mac OS X.

Application Block Diagram The following figure shows the application diagram of a typical flash disk product with AU6984. By connecting the flash disk to a desktop or notebook PC through USB bus, AU6984 is then turned into a bus-powered, high speed USB disk, which can be used as a bridge for data transfer between Desktop PC and Notebook PC.
