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 is the first TI DSP to pass all testing requirements for USB 2.0 full-speed certification, achieving USB compliance only one month after submission', said Christine Wu, C55x product marketing manager at TI.
'As the need for USB connectivity in portable appliances grows, TI's systems expertise and experience allow us to integrate the USB chip technology into the DSP.
This provides a proven USB 2.0 full-speed connection for direct access to the host platform, such as a PC, set-top box or digital media centre'.

The C5509 DSP, the second member of the TMS320C55x DSP generation, maintains code-compatibility with the industry leading TMS320C54x DSPs, and features a new architecture that delivers the power-efficient performance and dedicated on-chip peripherals required for handheld 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% and allows the end product to offer more features in a smaller footprint.
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 today 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 off).
