3/9/2005 - Texas Instruments Incorporated (TI) (NYSE: TXN), continuing to innovate the highly integrated technology developers need to design more efficient embedded control applications, announced sampling of the TMS320F2801, TMS320F2806 and TMS320F2808 digital signal controllers. Combining the real-time performance of TI's leading digital signal processors (DSP) with the peripheral integration, C-language efficiency and ease of use of a microcontroller (MCU), the new TMS320F28xTM devices are optimized for motor control, digital power conversion, and intelligent sensor control in industrial, appliance, automotive, medical, and consumer applications. An ideal mix of peripherals, including a patent pending pulse width modulator (PWM) with 64 times higher resolution than the nearest competitor, reduces external component count to provide a complete embedded control system with 100 MIPS of 32-bit DSP performance for less than $5 in volume. For more information on the F2801, F2806, and F2808 controllers, see www.ti.com/f280xpr.
Unique Peripherals Enable Enhanced Applications
The TMS320F2801, F2806, and F2808 controllers offer unprecedented PWM technology providing 16 bits of accuracy in a 100 KHz control loop and 12 bits at 1MHz. Competing processors limit accuracy to less than 10 bits at 100 KHz. In digital power applications, higher resolution PWM results in a faster transient response with a smaller ripple amplitude. F28xTM controllersí unique accuracy eliminates Ďlimit cycleí issues, enabling power supply designers to employ digital control in high switching frequency supplies like those found in wireless base stations, network servers, and even digital televisions, resulting in cleaner power output, higher power density, smaller magnetics, and more compact, cooler supplies than are possible using analog technology.
The F2808 controller also provides a highly accurate, 16-channel, 12-bit analog-to-digital converter (ADC) with the conversion speed (up to 6.25 MSamples/s) needed for even the highest performance embedded control applications, providing a cost-effective single-chip blend of 32-bit DSP and high-performance analog peripherals.
Unparalleled Performance and Integration
The F28x DSP core architecture features a 32-bit wide data path for superior performance and mixed 16-/32-bit instruction set for improved code density. The F28x offers unmatched system integration for a controller of its class, providing complete control system capabilities from signal input through the on-chip ADC, quadrature encoder pulse (QEP), and timer captures and compares through signal output with up to 16 independent PWM channels, enabling a single F2808 to control up to five independent three-phase motors. Comparatively, competitorsí DSP-based devices only provide up to 60 MIPS of 16-bit DSP performance.
Customer requests for system flexibility and development ease were a priority in designing the new F28x controllers. Developers can operate each of the PWM channels, timers, QEPs, and captures either independently or synchronized together. Modular design of F28x peripherals reduces overall system cost through enhanced scalability and reuse, increases ease of development, and accelerates time to market by allowing developers to, for example, leverage a single software driver across an entire peripheral set. In addition, scalable peripheral integration and memory in footprint compatible packages allow OEMs to easily reuse their hardware and software designs across their product portfolio.
Pricing and Availability
Sampling now, the TMS320F2801 controller is $4.95, the TMS320F2806 is $7.45, and the TMS320F2808 is $9.95, all in production quantities. Each device will be qualified to the Q100 automotive standard and available in both a 100-pin LQFP and 100-ball BGA package, with volume production for all three devices scheduled for the third quarter of 2005.
The F2808 eZdsp Starter Kit (TMDXEZS2808), available now for $495 through TIís authorized distributors and on the web, includes hardware tools, TIís comprehensive Code Composer StudioTM integrated development environment (IDE), and application software backed by expert training and extensive online support materials to get designers started developing embedded control applications immediately.
