Overview
The Delfino™ TMS320F28377D-EP is a powerful 32-bit floating-point microcontroller unit (MCU) designed for advanced closed-loop control applications. It features a dual-core architecture with two TMS320C28x 32-bit CPUs, each operating at 200 MHz, and includes IEEE 754 single-precision floating-point units (FPUs), a Trigonometric Math Unit (TMU), and a Viterbi/Complex Math Unit (VCU-II). This MCU is particularly suited for applications such as industrial drives, servo motor control, solar inverters and converters, digital power, transportation, and power line communications. The dual-core C28x architecture significantly boosts system performance, and the integrated analog and control peripherals enable designers to consolidate control architectures and eliminate the need for multiprocessor systems in high-end applications.
