Patent-pending PWM technology that TI says offers 64× higher resolution than its nearest competitor is the backbone of this new line of digital signal controllers. Based on the company's TMS320 DSP technology, the new F28×™ devices feature a highly-integrated, control-optimized peripheral mix targeted for embedded control applications.
The F28×™ devices reduce external component count to provide a complete embedded control system with 100MIPS of 32-bit DSP performance for less than $5 in volume. These controllers are designed for applications ranging from digitally-controlled power supplies, and laser-based air and medical sensors, to high-performance, vector-based motor control. The technology enables faster control loops, quicker system response and more accurate control systems, making the controllers ideal for digital power conversion, motor control and intelligent sensor control. Modular peripheral design reduces system costs, accelerates time-to-market, and provides single software drivers across entire peripheral sets. The 16-channel/12-bit ADC offers conversion speeds up to 6.25 MSamples/sec for high-performance embedded control. In digital power applications, the high-resolution PWM enables faster transient responses with smaller ripple amplitudes. System accuracy eliminates 'limit cycle' issues, enabling use of digital control in high switching frequency supplies like those found in wireless base stations, network servers and digital televisions for cleaner power output, higher power density, smaller magnetics and more compact, cooler supplies than possible using analog technology. The F280× controllers integrate a number of peripherals including 128 Kbytes of Flash memory, the 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. High integration capabilities enable a single F2808 device to simultaneously control up to five independent three-phase motors. 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. For more information, go to http://rbi.ims.ca/4917-641. View larger product image
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
