CAST and Innovative Semiconductors Create Integrated USB-OTG Solution

6/14/2004 - Semiconductor intellectual property (IP) providers CAST, Inc. and Innovative Semiconductors, Inc. announced a new relationship under which they will deliver a complete, easy-to-use package for physically implementing USB 2.0 On-The-Go (OTG) connections in a variety of electronic products.

The new offering combines the CAST CUSB2-OTG core with the Innovative SL210 USB 2.0 OTG mixed signal PHY hard macro core. This gives designers the functionality of CASTís host/device controller core and the silicon-proven mixed-signal circuitry of Innovativeís physical layer transceiver together in a tested, ready-to-implement configuration.

The new package is available next month for several ASIC technologies, and includes full documentation and a complete test environment that helps designers verify the functionality and compliance of their OTG implementation. Customers may contact either company for more technical and pricing information.

About USB 2.0 On-The-Go
The CAST/Innovative USB-OTG package fully conforms to the USB Implementer Forumís 2001 OTG supplement to the USB 2.0 specification.

USB OTG promises to build on the popularity of USB (Universal Serial Bus) by making it even easier to connect digital products. Whereas USB needs a computer host to manage the connection to one or more devices (a master-slave protocol), OTG gives every device enough host capabilities so they can be directly interconnected. Users will be able to, for example, connect their OTG-equipped camera directly to a printer for photos or to a cell phone for Internet sharing, without the use of a computer. (See for more information.)

CASTís core implements a port that can serve as either a master or a slave when connected to another USB device. Its efficient design features special hardware for the host negotiation protocol (HNP), session request protocol (SRP), and other time-critical functions. Designers can take advantage of the coreís FIFO interfaces, and can program up to 16 IN and OUT endpoints to further optimize the core for their specific application. The CUSB2-OTG core includes a flexible, user-programmable general interface to 8/16/32-bit microprocessors. It communicates with the Innovative PHY through a standard USB Transceiver Macrocell+ (UTMI+) interface.

The Innovative SL210 USB 2.0 OTG PHY Transceiver Core
Innovativeís transceiver core eliminates the challenges of mixed-signal design for USB-OTG by combining an analog front end with a digital back end in a silicon-proven hard macrocell. Using standard digital CMOS technology, the full-featured PHY includes an on-chip oscillator, termination resistor, DP/DM short circuit protection, and on-chip OTG comparators. It supports power down mode, and can handle data line VBUS pulsing session requests. The SL210 builds on Innovativeís portfolio of USB 2.0 certified products, which have been ported to many processes and incorporated in hundreds of customer products.
