SN11010
provides a high-performane interface to bridge
USB and ATA/ATAPI compliance device. By connecting
to external IDE hard disk, CD-ROM, CD-RW, or
Compact Flash card, it provides a flexible and
low cost single chip solution for applications
intended to utilize the convenience of USB.
An external serial EEPROM gives users the flexibility
to customize USB vendor ID and product ID for
various version of products. Drivers for Win
98, Win Me, Win 2000, Mac OS 8.6 and Mac OS
9.0 are provided by Sonix. ATAPI drivers for
CD-ROM and CD-RW is to be released in the near
future.

SN11011 provides a high-performance
interface to bridge USB and CF/ATA compliance
device, e.g. CF card or HDD. It provides a flexible
and low cost single chip solution for applications
intended to utilize the convenience of USB.
The DMA/Ultra DMA feature is not supported since
the bottleneck in data transfer between ATA
device and USB is on the USB side. An optional
external serial EEPROM gives users the possibility
to customize their USB VID and PID.
The USB Mass Storage Class compliance capability
of SN11011 makes it a truly "plug-and-play"
device without vendor drivers needed under the
OS supporting Mass Storage Class like Windows
2000/ME/XP and Mac OS 9/10. This feature not
only makes the system developing fast and easier,
but also reduces the cost and increases the
reliability of the final products.
For
OEM makers who wish to develop their own special
functions and application to uniquify their
products, SN11011 also provides a special vendor-specific
mode for the USB host(PC) to directly communicate
with the devices without being blocked by the
built-in firmware. This unique 2 modes architecture
(class and vendor-specific) not only let the
system designers to build standard products
easily, but also provide a simple method to
design their own unique product features.
