Overview
The TMS320F28377DZWTQ is a powerful 32-bit floating-point microcontroller unit (MCU) from Texas Instruments, designed for advanced closed-loop control applications. This MCU features a dual-core architecture based on TI's 32-bit C28x floating-point CPUs, each operating at 200MHz. The dual real-time control subsystems are enhanced by the Trigonometric Math Unit (TMU) and the Viterbi/Complex Math Unit (VCU-II), which significantly boost system performance. The integrated analog and control peripherals enable system consolidation and eliminate the need for multiprocessor systems in high-end applications. Development is supported by the DigitalPower and MotorControl software development kits (SDKs) for C2000 MCUs.
