SN11086
Second Generation USB1.1 Flash Memory Controller
Version 0.1

1 General Description
SN11086 is a high-performance integrated circuit to access the NAND type Flash memory
via the USB 1.1 bus. It provides a flexible and cost efficient single chip solution for external
storage applications such as USB Disk (Flash Disk). With the capability to be pin-to-pin
compatible to SN11085, the current user of SN11085 can easily upgrade to SN11086 with no
engineering effort needed at all. With all the features inherited from SN11085 like the low
6MHz system clock to reduce the EMI, the embedded translation table to eliminate the cost
of external memory, the Sonix proprietary randomization algorithm to extend the lifetime of
flash memory and ensure the product robustness, and the real time ECC correction function,
the SN 11086 adds several other unique features to reduce the cost of the end product and
meet the customer’s requirements.
To enrich the product line of the OEM manufacture, with the ability to support 8 pieces of
flash memories and the new types of 2G bits flashes, SN11086 can be used to build up a
storage device up to 2 Giga bytes. To reduce the total cost of the end product, SN11086
incorporates a power MOS inside to meet the current requirement (500 uA) in USB suspend
state. The usage of EEPROM can also now be eliminated by the capability to program the
customized vendor/product ID/string in the flash itself. Therefore, the total cost is reduced by
upgrade from SN11085 to SN11086.
For fulfilling different customers’ needs, SN11086 now provides several ways to build
different end products. The first one is to provide different security functions. The OEM
manufacturers can program one of the two ways in manufacturing via software. The flashing
ways of LED can also be selected by software now. With these flexibilities, the
manufacturers can easily build different products by using exactly the same components.

The USB Mass Storage Class compliance capability of SN11086 makes it a truly
“plug-and-play” device without vendor drivers under Windows 2000/ME/XP and Mac OS
9/10. SN11086 also provides PC boot up and data security function, which makes it an ideal
replacement for the legacy floppy disk.
