97 1 General Description SN11085 is a high-performance integrated circuit to bridge USB 1.
1 interface 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.
Several special features are implemented for an efficient and low cost USB storage device solution.
The embedded translation table eliminates external SRAM cost.
The Sonix proprietary randomization algorithm effectively extends the lifetime of flash memory and ensures the product robustness.
Embedded real time ECC correction keeps the data integrity while maintains the high data transfer rate.
The external serial EEPROM provides customized USB vendor ID, product ID, and string flexibility.
In addition, the EEPROM can contain a serial number which helps the system manufacturers to track down every single device they made even the design and PID/VID are all the same.
SN11085 also provides in system programming (ISP) capability of the EEPROM.
Products can be assembled without programming the EEPROM in advance, which saves both the production cost and time.
Device and manufacturer’s string can be saved in the flash instead of the external EEPROM for further total cost reduction.
The USB Mass Storage Class compliance capability of SN11085 makes it a truly “plug-and-play” device without vendor drivers under Windows 2000/ME/XP and Mac OS 9/10.
SN11085 provides PC boot up and data security function, which makes it an ideal replacement for the legacy floppy disk.
With many of its advanced features and high performance, SN11085 is an ideal choice for building a portable USB to flash storage system.
