Texas Instruments Inc. has introduced a high-speed USB 2.0 On-The-Go (OTG) dual-role controller that provides flexible architecture to meet a multitude of customer-defined applications. It can operate either as a function controller for a USB peripheral or as the host/peripheral in point-to-point or multipoint communications. This low-power device's idle mode operating at less than 100?A will extend battery life in consumer devices, such as mobile handsets, portable media players or video applications.

The TUSB6020 is a compact solution for space-conscious equipment and comes in a 5mm x 5mm package. It is certified to be compliant with the USB 2.0 OTG specification by the USB Implementer's Forum to help ensure interoperability with other USB devices. Its integrated USB 2.0 PHY provides design flexibility with one-port operation at a low speed of 1.5Mbps, full speed of 12Mbps and high speed of 480Mbps. The VLYNQ serial interface allows seamless interface to any VLYNQ-enabled application processor without loading the GPMC or EMIF ports.

The TUSB6020 will add high-speed USB capability to any TMS320DM643x DaVinci technology-based product.

The TUSB6020 is available in either an 80-pin TQFP package or MicroStar BGA/MicroStar Junior ZQE Package. Suggested resale pricing in 100-unit quantities is $7.50. In addition, samples and DM643x DaVinci software development kit daughter card evaluation modules are available online.
