  The CBM2098P is the USB 2.0 Flash Disk controller with the fastest transfer speed on the market. CBM2098P can reach theoretical flash access speed limit of over 32MByte/s for read and 20MByte/s for write. 

    The on-the-fly ECC engine is capable of correcting up to 72bits per 1024 bytes page . For data security, CBM2098P is designed with both hardware and software data protection technology to prevent data corruption even if it is powered off or unplugged during data transfer. 
    The CBM2098P supports all 8 /16 bit BUS wide async NAND flash memory available in the market. New flash can be supported by software re-configuration. 
    The CBM2098P supports all 8 bit BUS wide ONFI/TOGGLE NAND flash memory available in the market. New flash can be supported by software re-configuration. 
    The CBM2098P has both a) 5V to 3.3V LDO and b) power on reset circuits integrated. Thus greatly reduced BOM cost and eased layout burden. 
    The CBM2098P runs smoothly with all available hosts and PC platforms. Complied with USB specification rev. 2.0, the CBM2098P can be supported without additional driver under Win XP, Win 2000, Windows Me, Mac OS and Linux OS. With device driver installed, it can support Win 98/98SE as well. Comprehensive applications, such as PC boot up, disk partitions, password check for security disk, are available as part of our standard mass production software package. 
    The CBM2098P is available in 48-pin TQFP and 64-pin LQFP package, which are thinnest and smallest on the market. The 48-pin CBM2098P and the 64-pin CBM2098 all support up to 8 flash chips. Customers can choose different packages to meet their design requirement.
