USB2.0 Universal Flash Disk Controller

Unspecified 

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.
