TI Introduces Flexible, High-Speed Usb 2.0 On-The-Go Solution


Industry’s smallest form factor for consumer products

DALLAS - Texas Instruments (TI) (NYSE: TXN) today 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. 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 100uA will extend battery life in consumer devices, such as mobile handsets, portable media players or video applications. (See

The TUSB6020 is a compact solution 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 Mbps, full speed of 12 Mbps and high speed of 480 Mbps. The VLYNQTM serial interface allows seamless interface to any VLYNQ-enabled application processor without loading the GPMC or EMIF ports.

Other key features include the following:

* Uses industry-standard Mentor Graphics USB 2.0 OTG core
* Supports session request protocol and host negotiation protocol
* On-chip integrated 45-ohms high-speed termination, 1.5-k ohms pullup, and 15-k ohms pulldown resistors
* On-chip phase-locked loop to reduce noise on high-speed clocks
* Protection circuitry to withstand possible VBUS short

The TUSB6020 will add high-speed USB capability to any TMS320DM643x DaVinciTM technology-based product. Other USB devices from TI support PC and consumer electronics applications. Please see the Interface Selection Guide for more information.


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