USB to Flash Interface Controller, Mass

Storage Class Compliant

1 General Description

SN11083 is a high-performance integrated circuit to bridge USB and Flash

memory. It 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

features are implemented. The embedded translation table helps the system makers to

design a high performance NAND type flash device but still keeps the cost low. The

proprietary randomization algorithm effectively extends the lifetime of the 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 SN11083 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 SN11083 also 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, SN11083 is an ideal choice for building a portable USB to Flash storage

system.
