Texas Instruments (News
) (TI) has introduced a new high-speed Universal Serial Bus (USB) 2.0 On-The-Go (OTG) dual-role controller that offers a flexible architecture to meet a multitude of customer-defined applications.
TUSB6020 acts either as a function controller for a USB peripheral or as the host/peripheral in point-to-point or multipoint communications. Its idle mode operating at less than 100uA 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 the industry's smallest 5 mm x 5 mm package. It is compliant with the USB 2.0 OTG specification by the USB Implementer's Forum to help ensure interoperability with other USB devices.
In addition, the device 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 VLYNQ serial interface allows seamless interface to any VLYNQ-enabled application processor without loading the GPMC or EMIF ports.
Also, the OTG dual-role controller leverages Mentor Graphics (News
) USB 2.0 OTG core, supports session request protocol and host negotiation protocol. It also offers on-chip integrated 45-ohms high-speed termination as well as on-chip phase-locked loop to reduce noise on high-speed clocks and protection circuitry to withstand possible VBUS short. The TUSB6020 is capable of adding high-speed USB capability to any TMS320DM643x DaVinci technology-based product.
