1. Introduction
1.1 Description
The AU6980 USB 2.0 Flash Disk Controller is one of the best solutions for all kinds of
SLC (Single- Level Cell) and MLC (Multi-Level Cell) NAND and AG-AND with multiple
dies data flashes. The ability to support new flash in the market is powerful and in time.
Its high-speed read and write access performance enable users to transfer and
backup data effectively. Besides, AU6980 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.
The multi-function single chip AU6980 provides dual channel access and ISP
(In-System Programming) technologies, which are the most important features to
allow manufacturers building high performance UFD easily. In addition to being a
removable storage device, AU6980 can also be configured as a bootable disk for
system recovery..
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,
not only the data in a UFD could be protected from unauthorized access, but also the
PC computer could be completely locked out from people who do not have the
specific UFD. This feature increases the value of a UFD and leads users to the new
security generation at the same time.
1.2 Features
ꢀSupports dual channel mode for high-speed transfer.
ꢀ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. Using Alcor Micro‘s vendor driver
for the environment under Windows 98SE
ꢀConcurrent bus operation using multiple FIFO for better performance
ꢀIntegrates into flash memory power control switch
ꢀSupports bad block management
ꢀSupports dynamic serial number modification via mass production software
ꢀSupports software write protection
ꢀCompanion application program with UFD œ iStar available for users

2. Application Block Diagram
The following figure shows the application diagram of a typical flash disk product with
AU6980. By connecting the flash disk to a desktop or notebook PC through USB bus,
AU6980 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
