Texas Instruments has launched a high-performance-price ratio, real-time microcontroller that enables advanced motor control in home appliances and power tools.
The trend toward intelligence makes our lives and work more convenient and efficient. Consumers increasingly demand higher energy efficiency, smoother operation, and quieter operation from their home appliances and power tools. However, designing products that meet these requirements often costs more than consumers are willing to pay. To meet cost targets, system designers are forced to choose MCUs with lower computing performance and analog integration. Texas Instruments' newly released F28E12x series of MCUs addresses this challenge.
F28E12x Series MCUs: High Performance-price Ratio
Texas Instruments has introduced the C2000™ family of real-time microcontrollers, enabling high-end motor control for home appliances and power tools. These MCUs offer excellent value for money, enabling engineers to design industry-leading performance products at a lower cost.
Compared to previous C2000 MCUs used in single-motor and power factor correction systems, the new F28E120SC and F28E120SB MCUs offer 30% more computing power, helping to transform the performance of home appliances and power tools, such as washing machines, dishwashers, and vacuum cleaners.

The F28E12x series of MCUs integrates a C28x digital signal processor core with industry-leading analog peripherals, including high-speed analog-to-digital converters and programmable gain amplifiers, eliminating the need for additional components. This simplifies the design process and reduces product development costs.
This new MCU series features TI's proprietary InstaSPIN™ field-oriented control (FOC) software and advanced algorithms, enabling smoother, quieter, and more efficient motor performance. It allows motor speeds exceeding 120,000 rpm with a corresponding frequency of up to 2 kHz. This not only enables high-speed motor operation, reduces gear shifting noise, but also improves reliability, helping engineers design smoother and quieter products.
Advanced features include high-speed sensorless field-oriented control (FOC), high-torque zero-speed starting, and sophisticated vibration compensation technology, enabling highly accurate and responsive motor control for everyday applications. The vibration compensation algorithm reduces speed fluctuations by up to 60%, thereby counteracting acoustic noise and vibration issues caused by unbalanced loads.
Pre-production versions of the F28E12x series MCUs are now available on TI's website, offering a variety of packages and memory options. Engineers can also leverage TI's extensive development ecosystem to quickly and easily design motor control systems, including:
A companion LaunchPad™ development kit
Motor control and power control reference designs
A comprehensive motor control software development kit with code examples, application-specific algorithms, and a graphical device configuration tool
