Overview
The TMS320F28064UPNT is a 32-bit microcontroller from Texas Instruments, part of the C2000™ family. This microcontroller is optimized for processing, sensing, and actuation to enhance closed-loop performance in real-time control applications. It is particularly suited for industrial motor drives, solar inverters, digital power systems, electrical vehicles, transportation, motor control, and sensing and signal processing.
The F2806x family, to which the TMS320F28064 belongs, combines the power of the C28x core with highly integrated control peripherals, making it code-compatible with previous C28x-based code. The device features a high level of analog integration and supports single-rail operation with an internal voltage regulator.
