Its read and write access performance enable users to transfer and backup data effectively. Besides, AU9387 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 AU9387 integrates build-in regulator to save the cost of customers more. 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. It has auto-run function to prompt the designed AP automatically when plug into PC. In addition to being a removable storage device, AU9387 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, the data in a UFD could be protected from unauthorized access successfully. 1.2 Features PCBs are pin compatible in AU6980, AU6981, AU6982. Integrate build-in regulator Supports dual channel mode for 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 v1.1, 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 Support Auto Run function Support erasable and read-only mode AP Disk Companion application program with UFD – iStar available for users To have UFD partition management function To do password protection for the security in data access To guard data files with software write protection function To lock up PC by UFD as the key Available in 48-pin LQFP 7x7mm package to support 4CE pin flash Page 6 of 22 AU9387 USB1.1 Universal Flash Disk Controller V0.9W Preliminary release _ Confidential 2.0 Application Block Diagram The following figure shows the application diagram of a typical flash disk product with AU9387. By connecting the flash disk to a desktop or notebook PC through USB bus, AU9387 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.
