Overview
The TMS320F28377SZWTQ is a powerful 32-bit floating-point microcontroller unit (MCU) from Texas Instruments, part of the C2000™ Delfino microcontroller family. This MCU is designed for advanced closed-loop control applications, such as 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. Additional accelerators like the Trigonometric Math Unit (TMU) and Viterbi/Complex Math Unit (VCU-II) enhance the CPU's capabilities for trigonometric and complex math operations.
