Overview
The TMS320F28377D-EP from Texas Instruments is a powerful 32-bit floating-point microcontroller unit (MCU) designed for advanced closed-loop control applications. It features a dual-core architecture based on TI’s 32-bit C28x floating-point CPUs, each providing 200 MHz of signal processing performance. 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 integrated analog and control peripherals enable system consolidation and eliminate the need for multiprocessor systems in high-end applications. Complete development packages are available as part of the powerSUITE and DesignDRIVE initiatives.
