OTi-2168
USB 2.0 FLASH DISK CONTROLLER
DESCRIPTION
The flash disk controller (OTi-2168) is a USB2.0 mass storage class controller used to make a
linear flash device array look likes a normal disk, hiding the flash related problems with erasing.
The OTi-2168 is a controller with USB interface. The USB interface is for high speed operation
(480Mb/s). It conforms to USB Specification, Version 2.0. The USB transceiver is embedded in this
controller. With stable slew-rate control, the controller reduces EMI.
The OTi-2168 has a Phase Lock Loop (PLL) embedded. The PLL provides all clocks needed in
this controller. It needs an externally provided clock operating in 12MHz.
The OTi-2168 can control up to 8 pieces of NAND flash memory. The flash capacity can be 32M
bits up to 4G bits. And these chips can be any combination. It has been optimized to support Toshiba
and Samsung flash memory designs. It also supports Samsung’s K9F and K9W Series flash. The
controller has write-protected ability to prevent writing data to flash. The controller has one LED
control pin. You can program one of the display modes - operation, suspend, and standby, through
provided production program. Comprehensive application software for security function with Windows
OS is also available.
This controller can operate in Win XP, Win2000, Windows Me, and Mac OS without any driver
installation.
The OTi-2168 is available in cost-saving 48-pin LQFP (7mmX7mm) package.
