The AU9340 enabled Memory Stick card reader to be used as a removable storage disk in enormous data exchange applications between PC and PC or PC and various consumer electronic appliances. The AU9340 reads digital data saved on memory stick while users manipulating electronic devices such as digital cameras, MP3 players, PDAs and mobile phones… etc. By the AU9340, users can transfer information such as data, graphics, texts or digital images from one electronic device to another quickly and easily. With AU9340, users’ knowledge will be further enhanced by the Plug-and-Play nature built into latest operation systems such as Windows 2000/XP and Mac OS X. By integrating of various analog components, the AU9340 is the most powerful and most effective solution for Memory Stick card . 1.2 Features Fully compliant with USB v1.1 specification and USB Device Class Definition for Mass Storage, Bulk-Transport v1.0 Fully compliant with Memory Stick (MS) v1.3 Specification. Work with default driver from Windows ME, Windows 2000, Windows XP, Mac OS 9.1, and Mac OS X. Windows 98 is supported by mass storage class driver from Alcor. Ping-pong FIFO implementation for concurrent bus operation. Dedicated hardware engine for MS bus operation, average throughput over 1MB/sec for read, 680KB/sec for write operation. Support multiple sectors transfer up to 128MB to optimize performance Support optional external EEPROM for USB VID, PID and string customization Capable of handling 8 sets of built-in PID, VID and strings to minimize inventory control and improve lead production lead time LED for bus activity indication. Integrated power switch and power management circuit to meet USB 500uA power consumption during suspend with MS card in the slot. Runs at 12MHz, built-in 48 MHz PLL Built-in 3.3V regulator 28-pin SSOP package Page 6 of 23 AU9340 USB Memory Stick Card Reader Controller Chip V1.00 Official Release_Public 2.0 Application Block Diagram Following is the application diagram of a typical memory stick card reader. By connecting the reader to a PC through USB bus, the AU9340 is acting as a bridge between the flash memory card from digital camera, MP3 player, PDA or mobile phone and PC.
