SN11088

Third Generation USB1.1 Flash Memory Controller

Version 0.1

2003/10/8

1 General Description

SN11088 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 SN11085/86/87, the current user of SN11085/86/87 can easily upgrade to

SN11088 with no engineering effort needed at all. With all the features inherited from

SN11085/86/87 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 11088 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, 4G, and 8G bits flashes, SN11088 can be used to

build up a storage device up to 4 Giga bytes. To reduce the total cost of the end product,

SN11088 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 SN11088.

With keeping all the versatile functions provided by older products, like programmable LED

speed, FDD support, etc., SN11088 now provides CD-ROM support and separate write

protect features for different LUN, so the product makers can put their SW and manuals in

the flash directly without accompanying the extra CD-ROM, reducing the cost more.

Therefore, in total of 6 kind of different configurations can be selected by the flash disk
