Overview
The TMS320F28374SZWTS is a powerful 32-bit floating-point microcontroller unit (MCU) from Texas Instruments, designed for advanced closed-loop control applications. It is part of the C2000™ microcontroller family, which is optimized for processing, sensing, and actuation to improve real-time control performance in various industrial and automotive applications.
The MCU is based on TI’s 32-bit C28x floating-point CPU, providing 200 MHz of signal processing performance. It is enhanced by several accelerators, including the Trigonometric Math Unit (TMU) and the Viterbi/Complex Math Unit (VCU-II), which significantly boost the execution of complex mathematical operations.
The TMS320F28374SZWTS also features a Programmable Control Law Accelerator (CLA), an independent 32-bit floating-point processor that runs at the same speed as the main CPU, allowing for parallel processing and doubling the computational performance of the system.
