DSPs optimised for industrial control
27 June 2007, DSP, Micros & Memory

The TMS320F28044 and F2809 digital signal controllers from Texas Instruments offer 100 MIPS of 32-bit DSP performance optimised for industrial applications like digital power management, servomotor control and intelligent sensor control.

These devices feature a 32-bit wide data path for high performance and a mixed 16/32-bit instruction set for improved code density. They also feature a patent-pending PWM with 150 ps resolution. This high-resolution pulse-width modulation (HRPWM) technology provides 16-bit accuracy in a 100 kHz control loop and 12-bit at 1,5 MHz, which is unprecedented according to the manufacturer. In digital power applications, for example, higher resolution PWM results in a faster transient response with smaller ripple amplitude. The accuracy of the HRPWM eliminates 'limit cycle' issues, which means power supply designers are now able to use digital control in high-switching frequency supplies like those found in wireless base stations, network servers, and even digital televisions.

The F28044 allows power system designers to transition to software-controlled, digital power management using a 32-bit processor and is targeted at multichannel point of load (POL) applications such as telecommunications and networking infrastructure equipment, servers, laptop computers, and industrial equipment. Because one device performs all loop control, sequencing, system management and communications for up to 16 DC rails, designers save costs by eliminating individual analog converters, standalone sequencing chips and communications MCUs previously used in complex POL applications.

The F2809 controller offers exceptional system integration, providing complete control system capabilities from signal input through the on-chip ADC, quadrature encoder pulse (QEP), and timer captures and compares through signal outputs with up to 16 independent PWM channels. The 12,5 Msps, 12-bit ADC boasts an effective number of bits of 10,9 and is valid across the full -40 to +125°C temperature range. Key communication interfaces include multiple CAN, I²C, UART and SPI ports.
