Texas Instruments' F28x line of digital signal controllers employs high resolution PWM technology. Based on the company's TMS320 DSP technology, the F28x devices feature a highly-integrated, control-optimised peripheral mix targeted at embedded control applications.
According to the company, these devices reduce external component count to provide a complete embedded control system that delivers 100 MIPS of 32-bit DSP performance.
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, claims Texas Instruments, making the controllers very well-suited for digital power conversion, motor control and intelligent sensor control.
According to the TI, their 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 Msps 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 F280x controllers integrate a number of peripherals including 128 KB of Flash memory, the 12-bit, 16-channel 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 advanced execution performance while mixed 16-/32-bit instruction achieves superior code density. Key communication interfaces include multiple CAN, I²C, UART and SPI ports.
