MCUs decrease cost and complexity in resolver-based motor control systems

32-bit C2000 Delfino microcontrollers (MCUs) from Texas Instruments Incorporated (TI) solve a prevalent digital motor control design problem because they do not need a dedicated resolver-to-digital converter, which lowers system cost while delivering more efficient motor control capabilities. These high-performance, floating-point Delfino microcontrollers with an on-chip, high-precision analog-to-digital converter, along with an external low-cost signal conditioning circuit, provide motor control designers an alternative to more expensive and complex semiconductor solutions.

Features:

  • Up to 300 MHz C28x core provides fast interrupt response, minimal latency, execution of complex control algorithms and real-time data analysis.
  • 32-bit floating-point unit eases programming of magnitude calculations, eliminates scaling and saturation burden and improves performance of algorithms such as Park transforms and proportional integral derivatives (PID).
  • Up to 516 KB of on-chip, single-cycle access RAM enables high-speed program execution and data access.
  • Up to 65ps flexible, high-resolution pulse-width modulators (PWMs) allow for optimal precision.
  • CAN, I2C, SPI and standard serial interface (SCI) peripherals enable easy connectivity for management of system communication.
  • Internal 12-bit, 12.5 MSPS ADC and the option for an external ADC with the analog-to-digital converter (ADC) interface, giving developers flexibility to use the on-board ADC or select from TI's broad portfolio of high-accuracy ADCs, such as the ADC161S626, ADS1205 and ADS1209.
  • Code compatibility across the C2000 platform enables developers to easily scale product lines and reuse code in controllers ranging from 40 MHz Piccolo microcontrollers to 300 MHz Delfino microcontrollers.

Delfino microcontrollers start at $8.95 USD in quantities of 1,000 units.
