TMS320F280xx DSCs from TI

Texas Instruments Inc. (TI) has announced volume availability of four low-cost, DSP-based controllers. The TMS320F28015 and F28016 digital signal controllers (DSCs) offer 60MHz of performance starting as low as $3.25. The TMS320F2801-60 and F2802-60 controllers also offer 60MHz and are based on the current TMS320F2801 and F2802 devices.

As designers consider upgrading existing MCU-based designs, TI's F280xx controllers now offer a portfolio of 11 software- and pin-for-pin-compatible devices with 32bit DSP performance combined with the peripheral integration and ease-of-use of an MCU.

All F280x-based devices feature a 32bit-wide data path and mixed 16/32bit instruction set for improved code density. According to TI, these devices offer extraordinary system integration by providing complete control system capabilities from signal input through the on-chip12bit ADC, quadrature encoder pulse (QEP) interfaces, and timer captures and compares through signal output with up to 10 independent PWM channels.

Depending on the device, communication interfaces include CAN, I?C, UART and SPI ports. TMS320F28016 is said to be the lowest-cost DSC with integrated CAN communications. Long used in automotive networks, CAN is suitable for industrial applications that are susceptible to high noise levels and offer error detection and error handling for highly reliable communications within a system.

F280x controllers' patent-pending 150ps high-resolution PWM (HRPWM) provides 16bits of accuracy in a 100kHz control loop and 12bits at 1.5MHz, TI said, resulting in designs with cleaner power output, higher power density, smaller magnetics and more compact and cooler supplies. These features are important in applications such as AC/DC rectifiers that require high tolerances and faster transient response with small ripple amplitude. For motor control applications like white goods and automotives, overall system costs can be reduced through integration and lower device cost, while leveraging the 32bit performance necessary to implement advanced control techniques. Processor-intensive, sensor-less vector control helps developers reduce the power electronics required and the size and cost of a system's motors, the company explained.

All four controllers are AEC Q100 automotive qualified in 100-pin LQFP packaging and are available in production quantities. Developers can use the TMS320F2808 eZdsp Development Kit (TMDSEZS2808) to program all four controllers. It is available today for $495.
