Texas Instruments Launches Affordable C2000 MCUs for Enhanced Motor Control in Appliances and Power Tools

Texas Instruments (TI) has introduced the F28E120SC and F28E120SB, the latest additions to its C2000 real-time microcontroller (MCU) portfolio, designed for cost-effective motor control in household appliances and power tools. These MCUs offer 30% faster computing power than previous C2000 models, targeting single motor and power factor correction systems in devices such as washing machines, dishwashers, vacuum cleaners, and power tools.

The F28E12x series integrates TI’s C28x digital signal processor core with analog peripherals, including a high-speed analog-to-digital converter and programmable gain amplifier, reducing the need for additional components. The MCUs incorporate TI’s InstaSPIN field-oriented control (FOC) software and algorithms for sensorless FOC, high-torque zero-speed startup, and vibration compensation, enabling motor speeds up to 120,000rpm (2kHz electrical frequency). A vibration compensation algorithm reduces speed ripple by up to 60%, addressing acoustic noise and vibrations in applications like washing machines.

Vivek Singhal, vice president and general manager of Application-Specific Microcontrollers at TI, stated that the F28E12x series enables premium motor-control features at a lower cost, facilitating smooth and quiet operation in co...
