2002/6/26 0.2 SN11012 Confidential USB to SM/Flash Interface Controller, Mass Storage Class Compliant 1 General Description SN11012 is a high-performance integrated circuit to bridge USB and SM/Flash compliance devices. It provides a flexible and cost efficient single chip solution for external storage applications that intend to utilize the convenience of USB. To help the system manufacturers to build high quality, low cost USB storage systems, several special features are implemented. SN11012 can be easily configured to access SM and/or NAND type flash devices. With supporting flash memory capability, the combo system which supports both card reader and thumb drive can be built without any special effort. The embedded translation table help the system makers to design a high performance SM card or NAND type flash accessing device but still keeps the cost low. The proprietary randomization algorithm effectively extends the lifetime of the SM card and flash memory, ensuring the robu...
