1. 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.

2. 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.
