Overview
The TMS320F28377SPZPT is a high-performance 32-bit floating-point microcontroller (MCU) from Texas Instruments, designed for advanced real-time control applications. It is part of the C2000™ MCU family, which is renowned for its robust performance in industrial motor drives, solar inverters, digital power systems, electrical vehicles, and sensing and signal processing.
This MCU features a 32-bit C28x floating-point CPU operating at 200MHz, along with a Programmable Control Law Accelerator (CLA) that runs at the same speed. The CLA enhances the computational performance by executing code independently of the main CPU, allowing for more efficient handling of time-critical functions.
