Overview
The TMS320F28377DZWTQR is a high-performance, 32-bit floating-point microcontroller unit (MCU) from Texas Instruments, part of the C2000 family. This dual-core 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 device features two TMS320C28x 32-bit CPUs, each operating at 200MHz, along with IEEE 754 single-precision Floating-Point Units (FPUs) and Trigonometric Math Units (TMUs) for enhanced signal processing and mathematical operations.
The MCU also includes two programmable Control Law Accelerators (CLAs) that run independently of the main CPUs, significantly boosting the computational performance of real-time control systems. The integrated analog and control peripherals enable system consolidation, eliminating the need for multiprocessor setups in high-end systems.
