SN11030 is a high-performance integrated circuit to bridge USB and CF/ATA/SM/Flash compliance devices. SN11030 provides a flexible and cost efficient single chip solution for external storage applications that intend to utilize the convenience of USB. To help the system manufacturers to build high quality, low cost USB storage systems, several special eatures are implemented. SN11030 can be easily configured to access CF, ATA device, SM, NAND type flash or any combination of the above.This diversity in function relieves the component sourcing task of the system builders.With the ability to support flash memory, the combo system which supports both card reader and thumb drive can be built without any special effort. The embedded translation table help the system makers to design a high performance SM card or NAND type flash accessing device but still keeps the cost low. The proprietary randomization algorithm effectively extends  the lifetime of the SM card and flash memory, ensuring the robustness of the system. The real time ECC correction keeps the data integrity while still maintains the high data transfer rate.

The external serial EEPROM provides the possibility to customize the USB identity for each product. The OEM makers could make products for different customers by just putting the vendor/product ID and names in the EEPROM but still
keep other things the same. The serial number can help the system manufacturers to track down every single device they made even when the design and the PID/VID are all the same. The USB Mass Storage Class compliance capability of SN11030 makes it a truly "plug-and-play" device without vendor drivers needed under the OS like Windows 2000/ME/XP and Mac OS 9/10. This feature not only makes the system developing faster and easier, but also reduces the cost and increases the reliability.The SN11030 even provides the capability to boot the PC. Therefore, the system manufacturers can use it to build a much faster, high capacity, reliable, and portable system to replace the legacy floppy disk easily.

With so many functions built-in and the high performance, easy to design- in architecture, SN11030 is an ideal choice for building a portable USB to CF/ATA/SM/Flash storage system.
