OTi-2272 USB 2.0 FLASH Controller

The OTi-2272 is a single chip, cost-effective, high performance USB 2.0 Mass Storage Class Peripheral controller targeted for applications of USB Flash Disks. The design complies with USB High Speed Specification (480Mb/s), Version 2.0.

The controller Integrates the USB 2.0 transceiver with dynamic feedback control, stable slew rate, independent of external loading for reducing EMI. A Phase Lock Loop (PLL) is embedded provides all clocks needed in this controller. It needs an externally provided clock operating in 12MHz.

The OTi-2272 accommodates up to 8 Flash devices and works with comprehensive Flash memory technologies available on the market. The controller also has write- protect capability to prevent writing data to Flash.

The controller has one dedicated LED control pin and one optional LED control pin(GPIO). The LED display modes - operation, suspend, and standby, are programmable through the production program provided by Ours technology Inc.

There is more value-added application software available for security and personal data management.

This controller can operate on Windows Vista, Win XP, Window Me/98/98SE, Win2000, Mac OS and Linux system.

The OTi-2272 is available in cost-saving 64-pins LQFP (7mm X 7mm) package.
