TI Introduces New Design Tools and Three Low-Power TMS320C5000 DSPs

6/29/2004 - Continuing to help designers maximize battery life and reduce costs in portable applications, Texas Instruments Incorporated (TI) (NYSE: TXN) announced the availability of three new low-power digital signal processors (DSP) and new eXpressDSPTM power design tools that together enable developers to optimize power consumption to previously unattainable levels. Where other vendors can only show typical power consumption of core and memory, TI is the first company to “tell the rest of the power story” with design tools that show detailed and modular power information of a DSP chip core, memory and peripherals and a methodology for measuring power running under real-world conditions. The combination of the industry's lowest power DSPs and the essential tools to optimize power consumption and maximize battery life gives TI's customers the competitive edge they need when creating best-of-class portable, multimedia products.

New DSPs offer the Industry’s Lowest Standby Power
The new TMS320C5503, TMS320C5507 and TMS320C5509A DSPs offer an ideal combination of low power, performance, memory and peripherals for mobile, portable and other low-power, real-time signal processing applications. These devices enable advanced low power consumption through:

The C5503 is optimized for low-cost, low-power devices such as portable biometric or medical devices and handheld wireless applications. The C5507 is for applications such as wireless gateways, Voice over Internet Protocol (VoIP), GPS and wireless speakerphones and offers a 500 microseconds 10-bit ADC as well as USB 2.0 full-speed port for PC connectivity. The C5509A is optimized for multimedia-rich, mobile devices such as MP3 audio jukeboxes and infotainment devices and offers two MMC/SD ports, as well as a 500 microseconds 10-bit ADC and USB 2.0 full-speed port. Standard peripherals for all include three MCBSP ports, three timers, I2C bus, six-channel DMA, 16-bit EMIF, 16-bit EHPI and 36 GPIO. These are the first devices with integrated USB at this low a level of power consumption for this class of DSP.

Advanced Power Design Tools
Determining accurate power consumption early in the design process is essential for making the right tradeoffs in performance, peripherals activity and external memory use in order to maximize battery life and reduce cost. With the new eXpressDSP power design tools, TI will be the first to “tell the rest of the power story” by eliminating the guesswork of determining actual power consumption and giving developers previously inaccessible visibility into devices. These tools allow developers to consume only as much power as is actually necessary by dynamically turning off all peripherals and internal functional units when they are not needed and developers can now optimally configure devices based on accurate and detailed power consumption information, rather than blindly guess at how much power a device consumes. The four tools included in this eXpressDSP power design package are:

LabView-based Power Measurement Tool from National Instruments: Developers are now able to accurately profile power consumption based on actual application behavior. They can visually measure and analyze power by using the power measurement tool from National Instruments connected to the EVM320C5509A evaluation module (EVM) from Spectrum Digital or target prototypes. Measurements include total energy, max/average power, CPU and memory, peripheral and I/O power usage. Power/peripheral data can be viewed in tabular or graphical views forward or backward through time, as well as saved for future use.

Pricing and Availability
The new TMS320C5000TM DSPs are sampling immediately with volume production slated for August 2004. Recommended pricing starts at $7.50 for the C5503, $10.50 for the C5507 and $16 for the C5509A (10,000 unit pricing). The eXpressDSP power design tools are available as follows:
