Texas Instruments has introduced two new C2000 real-time microcontrollers, the F28E120SC and F28E120SB. These devices are designed for motor control and power factor correction systems, offering higher computing throughput than earlier-generation C2000 devices. The additional processing capacity supports single-motor drive systems in appliances and power tools that require precise and efficient operation.
Both MCUs integrate TI’s C28x digital signal processor core with analog peripherals, including a high-speed analog-to-digital converter and a programmable gain amplifier. This integration allows engineers to eliminate separate components, simplifying designs and reducing overall system cost. By combining signal processing and analog measurement functions in a single device, the controllers are well-suited for compact designs that must meet both performance and budget requirements.
The new series supports advanced motor-control techniques through TI’s InstaSPIN field-oriented control (FOC) software. These capabilities include high-speed sensorless control, torque delivery at zero speed, and vibration compensation. Engineers can use these functions to improve motor responsiveness, reduce mechanical stress, and achieve stable operation across a wide range of conditions.
With the ability to run sensorless FOC algorithms at speeds exceeding 120,000 rpm (2 kHz electrical frequency), the MCUs enable designs that minimize gear transition noise and improve overall reliability. The integrated vibration compensation algorithm provides measurable speed ripple reduction, helping suppress acoustic noise and vibration in applications such as washing machines with unbalanced loads.
Demonstrations of the new devices will include high-voltage three-phase fan control with total harmonic distortion reduction, as well as low-voltage vacuum motor control at speeds up to 150,000 rpm. These examples highlight the controllers’ ability to manage both high-speed and household motor applications within the same platform.
The F28E12x devices are now available in preproduction quantities, with multiple package and memory options. Design resources are accessible through TI’s development ecosystem to accelerate system integration and evaluation.
