The F28E120SC and F28E120SB MCUs are 30% faster than past C2000 MCUs
Texas Instruments (TI) has expanded its C2000 portfolio with new real-time microcontrollers (MCUs), the F28E120SC and F28E120SB MCUs
The new MCUs' computing power is 30% faster than previous C2000 MCUs for single motor and power factor correction systems, enhancing the performance of home appliances such as washing machines, dishwashers, vacuum cleaners, and power tools.
The F28E120SC and F28E120SB are powered by TI's InstaSpin field-oriented (FOC) software and advanced algorithms. The MCU's capabilities, including high-speed sensorless FOC, high-torque zero-speed startup and vibration compensation, help to provide exact and responsive motor control.
Consumers desire appliances and power tools that can operate efficiently, smoothly and quietly, but traditionally, designers have had to use MCUs with less computing performance and analogue integration to match cost targets.
The F28E12x series of MCUs is capable of solving this issue by performing in a way that enables enhanced motor controls at a reduced price. These MCUs integrate TI's C28x digital signal processor core and analogue peripherals, including an analogue-to-digital converter and programmable gain amplifier, simplifying designs and removing the need for any additional components.
Vivek Singhal, vice president and general manager, Application-Specific Microcontrollers at TI, said, "Since their introduction in the 1990s, TI C2000 MCUs have allowed designers to control both simple and complex motors with low latency and high reliability. Adding fully featured, ultra-low-cost MCUs to the C2000 portfolio enables new markets to access the industry-leading real-time performance that TI is known for. Using this technology, appliance and power-tool manufacturers can deliver seamless, quiet motor operation, previously considered a luxury, at an affordable price point."
TI's F28E12x series enables motor speeds over 120,000rpm, or 2kHz electrical frequency. Running the motor at such speeds can reduce gear transition noise and improve reliability so that engineers can design products with quiet operation.
The MCUs can run a vibration compensation algorithm, achieving up to 60% speed ripple reduction, counteracting the acoustic noise and vibrations created by an imbalanced load in applications like washing machines.
