Texas Instruments has introduced its most affordable C2000 real-time microcontrollers (MCU). The F28E120SC and F28E120SB MCUs deliver 30% faster computing power compared to previous C2000 MCUs for single motor and power factor correction systems, helping transform the performance of home appliances, from washing machines and dishwashers to vacuum cleaners and power tools.
Powered by TI’s proprietary InstaSPIN field-oriented control (FOC) software and advanced algorithms, these new MCUs enable smoother, quieter and more efficient motor performance. Their advanced capabilities – including high-speed sensorless FOC, high-torque zero-speed startup and vibration compensation – deliver precise, responsive motor control for everyday applications.
Today’s consumers demand appliances and power tools that operate as efficiently, smoothly and quietly as possible. Yet, historically, system designers have had to compromise by using MCUs with less computing performance and analog integration to meet cost targets.
The F28E12x series of MCUs helps solve this challenge by delivering the performance needed to enable premium motor-control features at a lower price than competing devices. These MCUs eliminate additional components by integrating TI’s C28x digital signal processor core and industry-leading analog peripherals, including a high-speed analog-to-digital converter and programmable gain amplifier, helping simplify designs and lowering costs.
Moreover, TI’s F28E12x series facilitates fast execution of the sensorless FOC algorithm, enabling motor speeds over 120,000rpm, or 2kHz electrical frequency. The ability to run a motor at high speeds reduces gear transition noise and improves reliability, enabling engineers to design products with smooth, quiet operation. The MCUs can also run a vibration compensation algorithm to achieve up to 60% speed ripple reduction, counteracting the acoustic noise and vibrations caused by an imbalanced load in applications such as washing machines.
