Digital Signal Controllers (TMS320F2801, F2806 and F2808)

Texas Instruments

By Design News Staff -- Design News, March 19, 2006

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.

Light Matters: The Unsung Heroes of Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
