SN11088 Datasheet | SONIX

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 patible 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 u A) 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 acpanying the extra CD-ROM, reducing the cost more. Therefore, in total of 6 kind of different configurations can be selected by the flash disk 2003/7/8 ver 0.3 manufacturers during the mass production stage, making production much...
