Starting at Less Than $5, TMS320F2801, F2806 and F2808 Devices offer 100 MIPS of 32-bit Performance
Digital Power Applications Surge Ahead
The TMS320F28x(TM) controllers' unmatched PWM technology enables the use of digital control in high switching frequency supplies like those found in wireless base stations, network servers and uninterruptible power supplies (UPS). As power system designers face increasing pressure to handle more complex power requirements such as managing higher efficiencies over wider loads, lower output voltages and multiple power supply synchronizations, digital power provides intelligent adaptability and flexibility to satisfy any complex power requirement with the straight-forward ability to monitor, process and adapt to system conditions.
TI based digital power solutions where recently highlighted when a team of undergraduate students from Monash University, Victoria, Australia won a $10,000 first-place prize in the 2005 IEEE International Future Energy Challenge (FEC) for their highly efficient power converter solution based on an F28x(TM) controller (see http://www.ti.com/monash ).
Early this year, TI announced its Fusion Digital Power solutions that includes the DSP based UCD9K high resolution digital power controllers which make power solutions much more energy efficient by providing the capability and flexibility to optimize power conversion over a broad range of loads. For additional information on TI's digital power supply solutions and the recently announced Fusion Digital Power(TM) line of UCD9K, UCD8K and UCD7K power solutions, see http://www.ti.com/digitalpower .
F28x Controllers Used For Medical and Industrial Intelligent Sensing Applications
Researchers at Rice University, Houston, Texas recently tested laser-based air and medical sensors using F28x controllers to detect the presence of specific gases in concentrations in the range of parts per billion to (ppb) parts per trillion (ppt). Pulsed quantum cascade (QC) laser-based sensors use laser absorption spectroscopy to measure electromagnetic radiation for applications including spacecraft air quality monitoring, breath analysis to detect certain medical conditions, volcanic emission monitoring and networked air monitoring of combustion sources and noxious gasses in urban-industrial settings. TI's highly integrated TMS320F2812 controller operates the lasers, converts and then processes the optical detector signals into highly precise measurements.
Unparalleled Performance and Complete System Integration
With a DSP core and the C-language efficiency and ease-of-use of a MCU, F28x controllers offer a leading 100 MIPS of 32-bit DSP performance and up to sixty-four times greater PWM resolution than competing architectures. The ability to position the edge of a PWM signal with 150 ps precision or 16 bits accuracy in a 100 KHz control loop enables faster transient response and smaller ripple amplitude to eliminate 'limit cycle' issues in digital power applications.
The F280x controllers integrate a number of peripherals including 128 KB of flash memory, a 12-bit, 16-channel analog-to-digital converter (ADC), 16 independent PWM channels, quadrature encoder pulse (QEP) and time stamping capture inputs for position sensing. This high integration enables a single F2808 device to control up to five independent three-phase motors simultaneously. A 32-bit wide data path ensures superior execution performance while mixed 16-/32-bit instruction achieves excellent code density. Key communication interfaces include multiple CAN, I2C, UART and SPI ports.
