specification and USB Mass Storage Class version 1.0 specification. Besides full speed 12Mbps
complied with USB1.1 specification, SK6211 can provide a 480Mbps transfer rate. Designed with an
enhanced power control circuit, the SK6211 fully complies with USB power specifications for bus-
powered devices, making it capable of bus-powered operation.
generation NAND which are manufactured in the most advance technology. In order to interface with
50nm NAND, SK6211 ECC capability can correct up to 13 bits error.
and 28MB/s for write access in HDBench.
requirement. Any UFD with SK6211 can easily meet 5 MB/sec throughput for random 4KB reads and 3
MB/sec throughput for random 512KB writes and market the UFD with enhancement for Windows®
ReadyBoost™.
Moreover, built-in regulator and POR (power-on-reset) can also save BOM cost.
certification without choke. It will be the biggest benefit to customer BOM cost. Therefore UFD with
SK6211 will have the best competitive price in the world.
all kinds of NAND Flash memories from Samsung, Hynix, Toshiba, Intel, Micron and other company,
either SLC or MLC, either small-page, 2K page or 4K page, and either x8 or x16 data width. The SK6211
allows the direct connection of up to 8 NAND Flash chips by 4 CE pins.

Compatibility & Flash Support
The SK6211 is an Enhanced USB2.0 Flash Disk controller that complies with USB version2.0
Besides rich features for UFD application, SK6211 is also addressing how to co-work with next
SK6211 ECC can provide 13-bit BCH or 8-symbol RS error correction code for 50nm MLC.
When dual-channel mode enabled, SK6211 can reach the theoretical limit at 34MB/s for read access
As emerging of Vista, SK6211 also implements a patenting algorithm to meet ReadyBoost™
SK6211 required the least numbers of passive components compared with competitor’s solution.
Regarding as FCC ClassB regulatoin, SK6211 had already proven to pass FCC/CE ClassB
With our superior designs, SK6211 runs smoothly on all most available host systems and supports
Therefore, SK6211 will be best choice according to cost per performance.
