Overview
The TMS320F28062PFPS is a 32-bit microcontroller from Texas Instruments, part of the C2000™ family. This device is optimized for real-time control applications, such as industrial motor drives, solar inverters, digital power, electrical vehicles, and sensing and signal processing. The F2806x family, to which this MCU belongs, combines the power of the C28x core with highly integrated control peripherals in low pin-count devices. It is code-compatible with previous C28x-based code and offers a high level of analog integration. The internal voltage regulator allows for single-rail operation, and enhancements include dual-edge control for the HRPWM module and analog comparators with internal 10-bit references.
