USB 2.0 OTG controller performs two functions

Dallas, Tex.—Texas Instruments (TI) introduced a high-speed Universal Serial Bus (USB) 2.0 On-The-Go (OTG) dual-role controller that provides flexible architecture to meet a multitude of customer-defined applications.

The TUSB6020 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 <100µA will extend battery life in consumer devices, such as mobile handsets, portable media players or video applications.

The TUSB6020 is a compact device for space-conscious equipment and comes in the industry's smallest 5 mm x 5 mm 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 1.5-Mbit/s, full speed of 12-Mbit/s and high speed of 480-Mbit/s.

The VLYNQ serial interface allows seamless interface to any VLYNQ-enabled application processor without loading the GPMC or EMIF ports.

The TUSB6020 uses industry-standard Mentor Graphics USB 2.0 OTG core and supports session request protocol and host negotiation protocol. It features on-chip integrated 45- high-speed termination, 1.5-k pullup, and 15-k pulldown resistors; on-chip phase-locked loop to reduce noise on high-speed clocks; and protection circuitry to withstand possible VBUS short. The TUSB6020 will add high-speed USB capability to any TMS320DM643x DaVinci technology-based product. Other USB devices from TI support PC and consumer electronics applications.

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