USB to CF/ATA/SM/Flash Interface Controller,
Mass Storage Class Compliant
1 General Description
SN11030 is a high-performance integrated circuit to bridge USB and
CF/ATA/SM/Flash compliance devices. 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. 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
