Overview
The TMS320F28069MPNT 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 this device belongs, combines the power of the C28x core with the Programmable Control Law Accelerator (CLA) and highly integrated control peripherals, all within low pin-count devices. This family is code-compatible with previous C28x-based code and offers a high level of analog integration.
