The PL-2521 Hi-Speed USB Cellular Mate and Flash Disk Controller is a highly integrated IC that works both as an easy-to-use cellular phone data exchange and portable USB 2.0 Flash disk device. In order to achieve these functions, the PL-2521 allows you to interface up to four NAND Flash Memories for storing the data. This is the best data managing solution for cellular phones without complicated operation.
 
The Cellular Mate function allows users to easily download/upload phone book addresses and short messages between the cellular phone and PL-2521 through the use of only two push buttons. The phone data is stored on the NAND Flash memories via an embedded file system with the file format compatible to most of the OS in the market. This means that end-users can also access and manage the stored files in their PC via the USB interface.
 
The Flash Disk function of PL-2521 allows the on-board NAND Flash memories to be used as a normal single disk or partitioned into a standard (open) mass storage device and a secured mass storage device. The sizes of the partitions can be easily configured and adjusted using the USB disk utility program where users can also set a password to lock the secured partition disk. In order to access the secured disk, users must need to enter the correct password using the utility program. Customers can preload the software driver and application program, or any other software utilities into the standard storage disk to save the extra disk cost and to enhance user convenience.
 
For true Plug and Play feature, the mass storage device is implemented according to the USB Mass Storage device class where the standard driver is already built-in within most of the current OS like Linux, Mac OS, Windows ME/2000/XP and above. Windows 98 requires a separate driver installation and is provided by Prolific.   The PL-2521 also provides options and software tools to customize the chip in showing the vendor and product identity. Customers can modify the Vendor ID, Product ID, Language ID, Manufacturer string, and Product string of the final product.
