AU6989SN-GT USB2.0 Universal Flash Disk Controller V1.00
1. Introduction
1.1 Description
The AU6989SN-GT (embedded Crystal) USB 2.0 Flash Disk Controller is the best
high performance solutions for MLC, TLC SDR/DDR NAND flash with multiple dies
data flash. AU6989SN-GT designs embedded crystal with Alcor’s patent and it has
72bit/1K BCH ECC engines to correct high error bits of new generation flash (1x/1y
nm) and provide the well performance for TLC flash especial DDR flash.
AU6989SN-GT provides dual channel access and ISP (In-System Programming)
technologies with Alcor’s patent, 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.
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
AU6989SN-GT. By connecting the flash disk to a desktop or notebook PC through
USB bus, AU6989SN-GT 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.
