GENERAL DESCRIPTION
Although the USB speed is increased 40 times from 12 M to 480 M, the external crystal frequency of SN20086 is still kept at 6MHz, keeping the EMI at low level. The functions that ensure the data integrity like the embedded translation table, the Sonix proprietary randomization algorithm, and the real time ECC correction function are all the implemented as the USB 1.1 version. SN20086 also incorporates Sonix in-house algorithm to improve the performance of the flash disk. To enrich the product line of the OEM manufacture and reduce the effort of component sourcing, SN20086 supports both single channel and dual channel modes in a single chip. In addition, SN20086 supports NAND flash memories of Samaung, Toshiba, Hynix, STMicroelectronics and Micron, providing more flexibility for the flash memory’s purchasing. With the ability to support 8 pieces of flash memories and the new types of 2G, 4G, and 8G bits flashes, SN20086 can be used to build up a storage device up to 8 Giga bytes large.
