Overview
The TMS320F28374SPZPS is a powerful 32-bit floating-point microcontroller unit (MCU) from Texas Instruments, part of the Delfino™ TMS320F2837xS family. This MCU is designed for advanced closed-loop control applications, including industrial motor drives, solar inverters and digital power, electrical vehicles and transportation, and sensing and signal processing. The real-time control subsystem is based on TI’s 32-bit C28x floating-point CPU, which provides 200 MHz of signal processing performance. The MCU is enhanced by various accelerators such as the Trigonometric Math Unit (TMU) and the Viterbi/Complex Math Unit (VCU-II), along with a Programmable Control Law Accelerator (CLA) that executes code independently of the main CPU.
