SK6203/SK6211/SK6281 Usb Flash Disk Controller

SK6211是一個效能加強版的隨身碟控制器，它能符合USB2.0的規格並能以極低功率來滿足USB bus-power的需求。

SK6211 的ECC糾正能力高達13bit，專為50nm MLC 特別設計。

　
Features: 　
Worldwide first UFD controller for 50nm NAND:
13-bit BCH or 8-symbol RS error control coding (ECC) suitable for MLC.
Sufficient embedded buffer for 4K page NAND.

Passing FCC/CE ClassB with choke.
The least passive components, about 12 pcs.

Outstanding R/W performance:
HDBench : Read: 32MB/s and Write: 23MB/s.
ReadyBoost :
>5 MB/sec throughput for random 4KB reads and,
>3 MB/sec throughput for random 512KB writes

Enable Multi-Partition features:
One Read-only Partition, two Read-Write Partitions and one Hidden Partition.
Each Read-Write Partition can be divided into Public Zone and Private Zone further.

NAND Interface:
Either single channel (x8 data width) or dual channel (x16 data width)
Support up to 4 CE pins, i.e. 8 NAND chips.
Up to 32GBytes addressing space.
