OTi-2168 USB 2.0 Flash Disk Controller

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 flash memory. It has been optimized to support Infineon flash memory designs. 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 TQFP and LQFP package.
