Overview
The TMS320F28378SPTPS is a high-performance 32-bit floating-point microcontroller from Texas Instruments, part of the C2000™ microcontroller family. This MCU is designed for advanced closed-loop control applications, including industrial motor drives, solar inverters, digital power systems, electrical vehicles, and sensing and signal processing. The real-time control subsystem is based on TI’s 32-bit C28x floating-point CPU, which operates at 200MHz and includes a Trigonometric Math Unit (TMU) and a Viterbi/Complex Math Unit (VCU-II) for enhanced mathematical processing capabilities.
The microcontroller also features a Programmable Control Law Accelerator (CLA), which is an independent 32-bit floating-point processor that runs at the same speed as the main CPU, allowing for parallel processing and significantly improving the computational performance of real-time control systems.
