Texas Instruments' DSP achieves USB 2.0 full-speed certification

Oct. 16, 2001--A DSP from Texas Instruments Incorporated has achieved Universal Serial Bus 2.0 full-speed certification from the USB Implementers Forum, Inc. compliance program, providing designers of DSP-based personal and portable appliances a proven solution for USB connectivity.

The TMS320C5509 DSP from Texas Instruments Incorporated (TI) (NYSE: TXN) has achieved Universal Serial Bus (USB) 2.0 full-speed certification from the USB Implementers Forum, Inc. (USB-IF) compliance program, providing designers of DSP-based personal and portable appliances a proven solution for USB connectivity. The certification allows designers of hand-held multimedia products with USB 2.0 full-speed specification ports to achieve full USB data transfer speeds of up to 12 megabits per second (Mbps) and seamless interoperability with other USB compliant devices.

Compliance means that USB products are built to match the description in the USB specification, so that devices designed with the C5509 DSP USB connection will be interoperable with other USB compliant devices from other manufacturers- saving design time, money and additional testing. Compliance testing exists to help manufacturers measure how well their products match the USB specification.

The C5509 DSP, the second member of the low-power TMS320C55x DSP generation, maintains code-compatibility with TMS320C54x DSPs, and features a new architecture that delivers the power-efficient performance and dedicated on-chip peripherals required for hand-held multimedia applications such as digital imaging devices, personal video cameras, personal medical, biometric identification systems and security devices.

TI's C5509 DSP incorporates functions that would otherwise need to be enabled by external devices, reducing board space, parts count and overall product cost. This integration combined with the inherent power efficiency of the C55x DSP improves battery life up to 70 percent and allows the end product to offer more features in a smaller footprint.

The C5509 DSP is supported by the most complete, field-proven development platform in the industry -- eXpressDSP real-time software technology. This suite of software and tools features the Code Composer Studio Integrated Development Environment (IDE); the DSP/BIOS real-time kernel and a large and growing range of application software compliant to the TMS320 DSP Algorithm Standard from TI's third-party network. In addition, TI provides a USB module support library that is built upon the C55x Chip Support Library, a component of Code Composer Studio v2. This USB Chapter 9 compliant example serves as a framework for USB application development, making it easy to program and configure the USB peripheral and is downloadable for the web.

The C5509 DSP augments TI's existing portfolio of USB 2.0-compliant products including peripheral and hub devices. TI offers USB 2.0 solutions, which provide superior functionality and versatility, encompassing the entire USB 2.0 operating range, including low, full and high-speed operation.

Samples of the TMS320C5509 DSP are available in 144-pin LQFP and 179-pin MicroStar BGA packages. Full production is scheduled to begin in the first quarter of 2002 at a price of $18 (10,000 qty). The C5509 DSP evaluation module (EVM) is available from Spectrum Digital (www.spectrumdigital.com), a TI third party, for a limited time at $995.
