AU6987 USB2.0 Universal Flash Disk Controller V1.0.1

1. Introduction

1.1 Description

The AU6987 USB 2.0 Flash Disk Controller is the best high performance solutions for

SLC, MLC, TLC NAND and AG-AND with multiple dies data flash. Its high-speed read

(32MB/Sec) and write access performance enable users to transfer and backup data

effectively. Besides, AU6987 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,

AU6987 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, AU6987 features the auto-run function to prompt the designated AP

automatically when plugging into PC. In addition to being as a removable storage

device, AU6987 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.
